I also tried some methods to optimize the test conditions, but there was basically no big change. So its your 3 stripe 2 mirror. My network Card is a Connectx-4, and works well with SR-IOV vfs, but I'm hoping to Your numbers are very slow for SSD. We have Intel Xeon E5-2697 configured in performance mode so 2. Within the cluster, we use CephFS as storage for shared data that Hi everyone, recently we installed proxmox with Ceph Luminous and Bluestore on our brand new cluster and we experiencing problem with slow reads inside VMs. 2 Cluster and having problem my Linux guest VM. ceph tell osd.

I'm now trying to use fio with ioengine=rbd to benchmark the setup, based on some of the examples here. Is this possible? I know HOST2 (SATA SSD slog, 4 disk RAIDZ1 underneath): 6553 IOPS HOST3 (SATA SSD): 3142 IOPS Turning off the slog for the first two, I get: HOST1 (3 disk JBOD): 3568 HOST2 (4 disk RAIDZ1): 700 A quick google shows real world testing on those drives giving 400 IOPS as an achievable goal, so in a mirror I would expect comparable IOPS to that. 3GHz / 3. With mdadm you don't get bit rot protection so your data can silently corrupt oder time, you get no block level compression, no deduplication, no replication for fast backups or HA, no snapshots, Round 2 - Run 10 - Test 2: sync 16K random read/write Fio on host: By papers, this SSDs can make more higher iops (in x1k to x10k numbers, depends on block size etc. I'm not expert at all in benchmarks (and in fio) and I'm very cautious concerning benchmarks, maybe my benchmark is not relevant at all. However I noticed that the IO Delay stat on the host summary page moves between 0 and 3%. Until now, I didn't bother digging further as I thought it was a motherboard issue. Not only did the average IOPS drop as you'd expect, but the average latency jumped due to queueing. I am not sure if this test is the best, but it shows a difference. 84TB Samsung P893's (with another 9 on order, so 4 per node). When copying a lot of files onto a VM (tested with linux and windows10) copy speed drops to 0 after some seconds. 987 180 I tested IOPS in LXC container on Debian 12. 2 with a ceph storage (internal to Proxmox) and I have made a benchmark in a VM with fio. 6. For testing, we used a RAID 6 with 10 drives with a 128kb strip size created in user space. So its like I thought.

We tried different settings in proxmox VM but the read speed is still the same - around 20-40 MB/s. Hi @dominiaz, Let's take your information and reverse engineer the problem. All servers are connected to other server to Strange what happened there on the second set of test where I ran all journals. Compared to native speeds or Xen speeds, it is up to 5x the latency. streaming or random IOPS): $ elbencho --help-large Hi anyone have success with NFS Server over RDMA (ROCE) on the Proxmox Host directly? I love the low energy consumption avoiding TRUENAS VMs and Windows Server VMs, and running mostly LXCs and Host services. We purchased 8 nodes with the following configuration: - ThomasKrenn 1HE AMD Single-CPU RA1112 - AMD EPYC 7742 (2,25 GHz, 64-Core, 256 MB) - 512 GB RAM - 2x 240GB SATA Hi guys, I have PM 4. Basic System Configuration: Intel(R) Xeon(R) CPU E5-2650 0 @ 2. The writes with the larger block sizes also look okay for a cheaper SSD with a bit over 1000MB/s. I backup my DBs every hour, and VMs daily, so I'm quite protected for such an event. Proxmox is a highly capable platform for demanding storage applications. Hi, Ich habe ein frisches Proxmox System im Einsatz und benötige etwas Hilfe bezüglich der empfohlenen ZFS Konfiguration. e. 8. 4-4 Cluster : 3 node Ceph config : version : 17. Each disk produces about 420 IOPS on 4K blocks. Live statistics show how the system behaves under load and whether it is worth waiting for the end result. 2 ZFS drives raidz1-0 I have prepared a virtual machine with Debian 12 VirtIO SCSI single. Specification says about 180000 IOPS and 4000Mbps writing, 1000000 IOPS and 6800Mbps reading. Same container with BIND MOUNT exported by host and benchmark running on this shared folder, bandwidth of approx 70MB/s This is exactly the reason, why we don't recommend Theoretical network throughput and writing throughput are two different things. 80G - nvtank available 1. 2 IOPS] Test : 50 MB [C: 54. I have 5 SSD disks connected to P420i in HBA mode on DL380 Gen8. With three mirrors I meant 3 mirrors made of 2 disks each striped together. We run 4 nodes Proxmox Ceph cluster on OVH. long as it passes a stress test and IOPs and TBW is reasonable. Sequential write IOPS suffer, though random write IOPS improve. Random read I have hetzner AX61 server 2x sata ssd 240Gb for OS (zfs raid-1 uefi boot) 2x toshiba nvme u. Sum that up and a 1TB consumer SSDs TBW will be exeeded within a year. In case of testing scalability of 8 virtual machines performance, RAID was divided into 8 partitions to distribute the RAID resources among virtual machines. We think our community is one of the best thanks to people like you! Context : We want to run MySQL databases on Proxmox (kvm). But I don't understand why the performance of ZFS pool is so poor. 1-8 Proxmox is using ceph storage for VMs (full 2*10G network, mtru=9000, full high-perf ssd). ( with only one job I can reach 15K write IOPS ) My concentration is now on improving write IOPS. Disk read speed is acceptable everywhere. My idea was to install the OS on pro-sumer SSD's, OSD's on enterprise SSD's and extra storage OSD's for low use servers and backups on spinners. Machine Info: Proxmox 7. and osd side, for osd->osd replication). The Proxmox team works very hard to make sure you are running the best software and getting stable updates and security enhancements, as well as quick enterprise support. 32-042stab072.

I also did a test on a 1TB SATA Hard Drive I had On this test, the load avg has a maximum of just 8. Before I provide the results of our fio tests i would like to explain the test scenario: (see row "iothread + writeback cache" enabled). ### TLNR => read iops ~ 7700 and write iops ~ 2550 Hallo, heute, keinen Tag nach meiner Anfrage, habe ich bereits eine nette hilfreiche Antwort von TK bekommen: grob zitiert: Speziell bei den Samsung PM893 SSDs gab es unter ZFS (Proxmox) vermehrt Ausfälle, I/O Fehler, dessen genaue Ursachen auch in Verbindung mit Samsung noch untersucht werden. log --bandwidth-log" but the results for this test is NAME PROPERTY VALUE SOURCE nvtank type filesystem - nvtank creation Sun Aug 27 0:55 2023 - nvtank used 8. Proxmox VE reduced latency by more than 30% while simultaneously delivering higher IOPS, besting VMware in 56 of 57 tests. The result was about 1. 92, stdev=33. We have a guest VM running Ubuntu 22. cachemode=none, io threat=yes, discard=yes, ssd Hi everyone, I have a three node Proxmox VE Cluster to test Ceph for our enviroment. The last test to the far right you can see the gains. We think our community is one of the best thanks to people like you! Hello Proxmox Community, I am currently managing a Proxmox cluster with three nodes and approximately 120 hosts. The PBS box has a pair of 40Gb NIC's in a LACP to our Nexus I made an iops performance test between: 4x 990 pro 2tb as zfs raid10 (mirror+stripes) 4x 990 pro 2tb as mdadm raid10 with lvm The read iops on lvm are around 1,5x faster The write iops on lvm are around 2-3x faster I personally stick with zfs, because i need the zfs features more as the iops speed, but it's still maybe interesting to some ppl I ask for, because i did some performance tests with openvz inside a KVM. I tested disks with fio like that: fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=32 Special Test Nr. Why each disk is loaded the same as entire ZFS pool. 2 and standard simfs inside a KVM. sh sync_rand_32K: (g=0): rw=randwrite, bs=(R) An: pve-***@pve.

We've just replaced our cluster (3 nodes, 1 DC) with 3 x 3. One test with centos 6. I lost the IOPS data for SCSI + IO thread Conclusion Best bus type. 74 0. Both instances with VirtIO Drivers. * bench , the IOPS for each devices were . 6k iops (from client) <-- this looks very bad we will test linbit plugin for proxmox, but need to know, if NFS will be fast enough on ceph before we buy more nodes, because on 2/2 nodes the The real limitation for this is probably the number of disks available for IO per Proxmox VE node, and also do those disks have dedicated PCIE lanes. I just created a new proxmox backup server and made my first test. 191, NFS storage is I have a new Proxmox cluster setup, with Ceph setup as well. May 15, 2021 Hello, We are actually using proxmox on a 4 nodes cluster with a ceph storage with 2 OSD of 420GiB on each node except on the last node (2x900GiB). 94 219 up 1 hdd 0. 6TB NVME SSD to a fresh install of Ubuntu 19.

We think our community is one of the best thanks to people like you! If your workload is more blgger block (video streaming for example, less iops but bigger through), cpu is less critical. A container with a virtual disk stored on CEPHFS, benchmark running on its local /tmp, bandwidth of approx 450MB/s b. Here is what I tried so far: disabling ballooning: didn't help; changing machine version: no change; changing video card to VirtIO with more memory: no change Eigentlich gibts nur Performance Verbesserungen. 00x - rpool/test reservation none default rpool/test volsize 100G local rpool/test volblocksize 8K default rpool/test checksum on default rpool/test compression Hi everbody, we are currently in the process of replacing our VMware ESXi NFS Netapp setup with a ProxMox Ceph configuration. This technote series aims to quantify the efficiency of all storage controller types Read IOPS go up by a factor 1. Random read performance: To measure random read IOPS use command: fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=4G --readwrite=randread. As always, test your configuration before putting into production root@pve-11:~# ceph osd df ID CLASS WEIGHT REWEIGHT SIZE RAW USE DATA OMAP META AVAIL %USE VAR PGS STATUS 0 hdd 0.

Performance seems excellent and I have MPIO configured on every host. It is important to understand, that PCIe passtrough means to enable IOMMU and to give the NVMe as PCIe device to the VM, not as the block-device itself or a block-device created by a MBR or GPT partiton on the NVMe as suggested in the first results on Google. The maximum number of hosts that can be efficiently managed in a Ceph cluster. I've just set it up (yes, raid resync is long done) and moved my VMs from my other server. Since we have the P822 raid card the easiest approach will be to build the RAID array in the controller and use it directly from PVE, but we would like to give a try with ZFS since from many topics in the net can give us many advantages in terms of I recently purchased a used R730xd LFF 12-bay (3. Proxmox VE beat VMware ESXi in 56 of 57 tests, delivering IOPS performance gains of nearly 50%. iperf3 results show I am getting 10 Gbits between each node on all VLANs Hi guys A couple of month ago I've switched from P4 to P5 (new installation, no upgrade, OVH Proxmox pre-built template with soft-raid 5, same host) and am now experiencing bad disc performance with KVM (haven't used KVM instances in I have made an Proxmox cluster version 5.

I am getting extremely low write speeds on my minimal Ceph cluster of 3 nodes with 2 1TB Samsung QVO 860 SSDs each (total of 6 SSDs across 3 nodes). However, it doesn't appear to be working on Proxmox's Ceph setup out of the box: Hi all! I've got a HP DL380 G8 running with 2x300GB 15k SAS in RAID 1 and 4x300GB 15k SAS in RAID10. Today, I decided to pass through my NVMe to a Windows VM directly and ran some tests. Hi Guys, I've setup one of my new servers today for some testing. How can I troubleshoot this? Therefore, we kindly request your assistance in providing tips or recommendations to improve the performance. Controller has 1GB of cache, Write Cache is enabled, BBU is present. The cpu is main bottleneck depend of number of iops (not the size of the iops), because the crush algorithm need to be used. If you do a random write test of 4K blocks, you will see a significantly lower throughtput rate. Whats is the best way to test it properly? and where shall i check and fix it ? Your help will be appreciated, thanks Proxmox version: 5. Auf dem System sollen eine Reihe von VMs betrieben werden. If I run hdparm or dd directly on the host, I get speeds on the VM SSD disk of around 370-390 MB/s, which is A block-device is probably slower than PCIe passtrough due to the copying of data by the CPU. 18. We have a production system with SSD and 10GbE, read/write is around 150MB/s, IOPS are around 1000-2000. But interesting is, for me, this SSDs directly tested on Windows (not as VM, on same HW machines) gets mentioned nice papers IOPS performance. 203157 Max latency(s): 1. sh sync_seq_4M: (g=0): rw=write, bs=(R) The Proxmox system under test is a SuperMicro H13 server with a single AMD Zen4 9554P 64-core processor and 768GiB of DDR5 operating at 4800MT/s.

Each workload consists of a 1-minute warmup and a My disk performance: 10889 read operations per second (IOPS) and 3630 write operations per second. An adaptive external IOPS QoS limiter was used to ensure a sustained rate of 32K IOPS for each test configuration. Keep an eye on the free space there – you don’t want to create a test file that can run your server out of drive space. 6 / NMVE x 2 disks on ZFS mirror / Proxmox VE 4. Two to three Ceph disks (preferably SSDs, but spinning rust will work) plus a separate boot disk per Proxmox node should give reasonable performance in a light office scenario even with 1 GB restoring the backups is what i did (backed it up on pbs under pve7 and restored it on pve8). 53 Max IOPS: 106 Min IOPS: 63 Average Latency(s): 0. max_queue_depth= and found some articles, seams like a known bug The Proxmox community has been around for many years and offers help and support for Proxmox VE, Proxmox Backup Server, and Proxmox Mail Gateway. 2 up2date with ZFS mirror on two SSD disks. Maybe you have a wrong cache setting for your test nested hosts? Howdy! I have an HP server with two Intel Xeon processors and 16 drives (12 HDDs and 4 SSDs), having several ZFS pools between disks of the same type. I am going to now install proxmox 1. Peak gains in individual test cases with large queue depths and small I/O sizes exceed 70%. 4). 10 with ploop, a second test with proxmox ve 2. We think our community is one of the best thanks to people like you! Hello, Have a 4 x Server Proxmox 5. We test Proxmox configuration changes using a suite of 56 different I/O workloads. Also keep in mind, that a bs of 4k will benchmark IOPS, and a larger bs, (4M) will benchmark bandwidth. NFS storage is attached via 10Gb link too, and mtu is set to 9000. PBS needs IOPS which HDDs won't really offer so your HDDs IOPS performance might be the Adaptec 6805 + 8 Vertex3 Max IOPs Essentially the Z-Drive R4 600GB claims to do up to 2GB/s sequential R/W and up to 250,000/160,000 IOPS Random R/W (4K). I surprised about IOPS of VMs on proxmox always lower than IOPS of NVME SSD specification. Setup : 3-node Proxmox cluster. Performance is more than sufficient for the workloads being used (mostly DB & App Linux servers). You want to test where your data, log, and TempDB files live, and for fun, also test the C drive and your desktop or laptop for comparison. to 3.

Guest is a Debian 10 with ext4, ext4 parameters: default+noatime+nodiratime. xfs mounted Running the test generated 500-700 IOPs on one HDD and a load of >40 on the proxmox host - like inside the VM The proxmox host did not lock up (256GB memory), but the umount took over 5 minutes (fs buffers from memory had to be synced to the disk) I have had a Proxmox Cluster ( 9 Nodes, Dell R730's ) with 10GB network dedicated to CEPH backend, 10GB for internal traffic. (HP DL380 G8 with 2x Xeon E5-2670 and 128GB RAM, 2x 1TB HDD in RAID1) I have run fio on both hosts with the same This is my issue. I use 8 small servers (Atom c2750 with 8G RAM DDR· and 1 hdd SSD 256G crucial MX100) in an proxmox cluster (version 3. I have got unstable test results for my disk read performance. On the same test made some times ago with pure ZFS on raw disks they bring an improvement, but with the HW Raid with BBU cache, seems to become a bottleneck on DB workload (unexpected to be this huge). 96G - rpool/test available 215G - rpool/test referenced 9. The storage system under test is a DELL-NVME48-ZEN3 running Blockbridge 6. The differences are 4KB Random Read: 130000 IOPS 4KB Random Write: 39500 IOPS Server used for Proxmox: HPE ProLiant DL380 Gen10 - All the NVMe drives are connected directly to the Motherboard's storage controller. 8k/0. My test: Write: Proxmox: Proxmox: # fio --rw=read --name=IOPS-read --bs=8k --direct=1 --filename=test1. Additionally, we are interested in exploring the possibility of accessing your The idea was to use the 120gb SSD as system disk and the array of 4x SSD in raid 10 configuration for the VM datastore. testing directly on the disk im able to achieve some reasonable numbers not far away from specsheet => 400-650k IOPS (p4510 and some samsung based HPE) proxmox folk seems to have even worse result, sadly the test dosnt provide much insight . Controller status is ok. 00000 931 GiB 64 GiB 63 GiB 148 KiB 1024 MiB 867 GiB 6. 5”x 12 bay backplane) that I have installed Proxmox on and plan to use for some VMs 1x VM: read 28k, write 10k, readwrite 14k/5k iops <-- thats acceptalbe 1x VM (nfs server) + 1x VM (nfs client): read 11. I don't understand why I got very low IOPS on read operaions ? Run your test for longer periods of time, e. Each suite contains varying block sizes and queue depths. Recommended hardware specifications for achieving optimal IOPS and latency. 2 KXD51RUE3T84 3. But the Write performance is not more than 2k IOPS when more than 1 parallel jobs is running. Other options for the virtual disk show even worse IOPS. Hi I know that there is a lot of post of this in the forum, but I test lot of things and have no successful result on my server. Proxmox is 172. 8-4-pve and Zfs 2. You can see my performance overall tanked in the r/w test compared to my earlier post. atime=off, ashift=12, thin, compression=lz4, encryption=aes-256-gcm, volblocksize=8K, primarycache=metadata. Tests were conducted using Proxmox 7. 172379 Stddev Latency(s): 0. Proxmox detail : Version : Proxmox VE 7. 84Tb. 2/31. 2 SSDs (configured ZFS mirrored). 3, latest openvz repo/kernel 2. it was still only listing 500 IOPS on those devices. Wenn ich einen CPU As pointed out in the comments (by narrateourale) with a link to a Proxmox article, IOPS are more important. 512GB RAM in the boxes, local storage is a 22 disk RAID 10 of spinners. They are both running the same version of proxmox (8. 289669 2 16 103 87 173. 46068 Min latency(s Exactly, two mirrored consumer-grade NVMe (Transcend MTE220S), no PLP, but it's just an experiment. My problem is: 1. i will test later with some only one job, maybe that is the I prepared Proxmox 8 for testing on a Dell R640 with 3 U. We recently got a NetApp AFF-A250 and we want to test NVMe over TCP with proxmox. 9 and test it under no load, with a few containers and under load. I have created my OSDs, and my Ceph pool. 4. It has been previously connected, through passthrough, on an Dell R710 Current visitors New profile posts Search profile posts. I have created 2 linux VM's and a windows I've a SSD based Ceph cluster with 3 nodes, the read IOPS is about 250K with 96 parallel fio jobs ( running from 3 different nodes ), the reasults are fine. Some VMs are installed and working fine, the plan was to test IO of the HDD mirror (for storage applications) and then order a second one. Kernel 6. Due to cache, sequential read is IOPS=206k, BW=806MiB/s. Could you test Hello I recently add a NFS server to my proxmox architecture, for NFS backups. proxmox. 1 x bench over 10GbE Max Additionally I run the test on the proxmox host directly created a 4K zvol mkfs. 2-4. 04 LTS edition having 40GB RAM and 14 vCPU. After making your choices, click the All button. cachemode=none, io threat=yes, discard=yes, ssd emulation=yes, virtio SCSI, SCSI, virtio blocksize=4K. ) I tried to attach SSD into VM with Windows, but still get same low IOPS. I am seeing a huge difference in write performance on my proxmox hosts in a single cluster. The problem I'm facing is that a night ago, suddenly the server ended up having a huge consumption of resources. 19: Like Round 2 - Run 4 - Test 8 but 32K volblocksize + ext4 created with 32K clustersize (mkfs. the NVME drives seem to be SLOWER than the SATA SSD drives and none of my config changes have made any difference. Done a quick Disk Benchmark on my Homeserver (little Xeon with Enterprise-Disks): The "lost" between PVE Host & Debian VM is lesser than 4% (Writeback Cache enabled) While Benchmark is running, the I/O-Delay goes max up to 5-10% If it is your private Hp Server, i would reinstall it from scratch I am running the latest version of proxmox on a 16 node 40 gbe cluster. Proxmox VE is installed on 2 x480GB SSD in RAID-1 mode. Our ceph cluster is communicating on a dedicated vlan on a 1Gb/s Vrack (OVH, french hosting platform) Since the 10th of december, we were having Round 2 - Run 6 - Test X6: 4x async sequential read/write 32K Guest (part 2): @spirit those are pretty good stats. 4 here. 1 minute and compare the results then. Aktuell betreibe ich ein ZFS Raid 10 mit 4x Samsung 990 pro ashift 12 und Blocksize 8k (soll mal ne SQL Datenbank rauf), compression lz4 Es läuft eine nackte ubuntu VM auf dem Host. Dauerbelastung mit 100k IOPS gar kein Problem (ja ist halt kein 5 Node Cluster mehr). Bare-Metal NVMe: According to your benchmark, you achieved 40,400 IOPS on the local NVMe device with a QD1 read workload. From the tests so far, smartctl I have a 2 NVME's I want to pool and am trying to figure out what the best settings are for a VM storage disk on Proxmox. I have tested bandwidth between all My NVMe gets a maximum speed of 1. 90959 1. with sync Since there are many members here that have quite some experience and knowledge with ZFS, not the only that I`m trying to find the best/optimal setup for my ZFS setup; but also want to have some tests and information in 1 place rather than scattered around in different threads, posts and websites on the internet for Proxmox and ZFS. I have a test 3 node Proxmox cluster with 10 GbE full mesh network for Ceph. I'm seeing the same behavior with my longer term Proxmox 8. if you have a suggestion how to test 4k random read/write with fio on proxmox cli, feel free to answer. For the combined test r+w, ~+1000 read IOPS and +200-300iops write side 4k random write alone skyrocketed. Installing Proxmox in Virtualbox to test out its I have just replaced our backup server with a Dell machine running a pair of 8 core Xeon Gold 6144's with 512GB of RAM, and 24 x 12G 7. 90 0. Xeon Silver CPU 256GB DDR4 Samsung 1733 NVME drives As long as the VM is running on local lvm-thin type storage, the disk performance in the VM is blazing fast (7GB/sec read, 4GB/sec write) with low cpu load. Couldnt comment it really. 2. The servers is based on Intel platform R2308GZ4GC and contains two CPU Xeon E5-2630 6C, 64GB RAM, LSI MegaRAID SAS 9265-8i with BBU, 8x450GB 15K SAS disks. Any suggestions are appreciated. Crystal Mark on Proxmox Guest Windows 8. I want to setup a test ceph server using the proxmox ve servers. Das System verfügt über 14x PM883 3. My homeserver is running 20 VMs and these are writing 900GB per day while idleing where most of the writes are just logs/metrics created by the VMs themself. Mostly 0 but hovers around upto 3% every Tests include throughput, IOPS and access latency. As soon as I run Wait a minute! This says you are running the test on the host in a udev filesystem, which is a ram-based filesystem not a real disk. x or 8. 00| (RANDOM IO/S BY NUMBER OF JOBS) Similarly, the RND4K Q1 T1 WRITE test result is very bad, only 7k iops, and the physical disk has 51k iops, which I feel is unacceptable. You are basically testing the speed of the hosts RAM + udev filesystem overhead. The required minimum write speed for Tandberg LTO-6 drive is 54 MB/s System: CPU: 2x Intel(R) Xeon(R) CPU E5-2660 v4 @ 2. Installing Proxmox in Virtualbox to test out its features is something you can totally do, so cool!!! May I ask what kind of hardware you are running on (besides the Micron NVMEs)? Because the IOPS in the first (bs=4k) test are quite a bit higher (110k) than in our benchmarks. The network mir: For ATTO I have to register and wait for some email, HD Tune doesn't test write in free version. 3 GB/s) you are seeing there and also why direct I/O isn't supported. All my later OSDs after I upgraded to a later 8. Als Dateisystem setzen diesmal auf ZFS als Mirror That all really depends on your workload and setup. 6GHz turbo per core. 54 I have a cluster of 6 nodes, each containing 8x Intel SSDSC2BB016T7R for a total of 48 OSDs. 1. x, do not have values in my Configuration This is the pool and VM that will be used in Round 2 Run 4: Host is a striped mirror of 4x S3710 200GB. The first three OSD's have the osd_mclock_max_capacity_iops_[hdd/ssd] values when I initially installed the OSDs. 1 thing to test, is "physical_block_size=4096,logical_block_size=512" on disk. No SSD's yet, but still not slow. However, I'm still curious if this conclusion is accurate or if I'm In Part 4, we quantify and compare IOPS, bandwidth, and latency across all storage controllers and AIO modes under ideal conditions, utilizing Windows Server 2022 Proxmox exposes several QEMU storage configuration options through its management interfaces. VM disk info Proxmox VE beat VMware ESXi in 56 of 57 tests, delivering IOPS performance gains of nearly 50%. Get started by selecting what you want to test Large shared files or block devices (e. Hi all, I'm testing some different hypervisors for my future cluster. Hi all, incremental backups from all servers takes about 15 Minutes, but (re)sync between two Backup Servers 2. Hello, I would like to ask you for help because I am running out of ideas on how to solve our issue. Storage for both tests are HP P 2000 (SAS) with a bunch of raid 10 spindels. 00000 931 GiB 63 GiB 62 GiB 20 KiB 1024 MiB 869 GiB 6. Warum machst du denn den Public und Cluster Traffic nicht beides über die 100G Verbindung? Auch da kannst du ja VLANs zur Trennung nutzen und eventuell andere Verbraucher in das Public Netz connecten lassen. i will look into it. 84Tb (for data) Test with fio data pool Moin!

The internal network for the cluster is built on OVH vRack with a bandwidth 4Gbps. Updated test results, same setup (the only difference is that we added more RAM, previously was 64 GB, now 480 GB): Hello together, we try to backup datastore to tape, but the write stream falls below the minimum speed. 3 on a 16-core AMD RYZEN 5950X processor with Mellanox 25-gigabit networking in a production customer hosting environment. Register Round 2 - Run 3 - Test 3: sync 4M sequential read/write Guest: root@DebianTest2:~# bash /root/benchmark_c_3. I am using bluestore for all disks with two crush rules, one for fast nvme and slow for hdd. tldr: The test data shows a clear and significant performance improvement that supports the use of IOThreads. Use either SCSI or VirtIO. If i change virtio on IDE my iops on write more then 8000-13000. NVME drives root@serverminion:/# Hi, wir haben einen neuen Server bestellt (AMD EPYC 7402, 128GB RAM, 2x SAMSUNG MZQL2960HCJR-00A07). snowman66, spirit: DELL PERC H710 Mini 6Gbps - 03:00. All are on the same subnet (LAN), Greetings! We are looking at building a 4 node HA cluster with Ceph storage on all 4 nodes and had some questions on some items in the FAQ. 1 32bit, image stored on 'Directory storage' local SSD. Disk write speed is acceptable on hypervisor and well as in LXC containers: In PM: dd if=/dev/zero of=brisi bs=10M count=200 oflag=dsync 200+0 records in 200+0 records out 2097152000 Hi guys, I operate a 16 node cluster with 10Gbit iSCSI through to a HP SAN as my VM storage. com Betreff: [PVE-User] SSD Performance test Hi all, I'm doing some tests with a Intel SSD 320 300GB disk. Again just to be clear, the 4k tests will run into the IOPS limit and the 1M/4M tests will run into the bandwidth limits. I want to create a demo proxmox ve server and create 3 vm with proxmox ve on the demo server to have 3 ceph nodes. We do have NVMe/TCP working on VMware and in a windows environment it gives Depending on what you want to measure (throughput/IOPS/latency and sync/async) you need to run different fio tests. For the testing I used my business software, which actively uses In this article we will discuss how to check the performance of a disk or storage array in Linux. proxmox v6. 1-35 Node-1: HP Proliant ML350 G6. 90919 1. related system functions (i. I tried to test the storage performance of PVE ceph, but the performance I got was very low. One is for the host itself, and the other is for the virtual Disks for the VMs and containers. 30K iops rand read (10Gbps link is the bottleneck, LACP will not apply with just one vm issuing I/O on a single pipeline) 20K iops rand write for 620MB/s 12 CLONES TEST : At this time LACP kicked in to break the 10Gbps single im pretty new on proxmox VE, and finding a sotrage solution for performance and stabiility. In general, IOPS refers to the number of blocks that can be read from Hi, kann es sein das die Virtuellen Server eine schlechte HDD speed haben auf einem local Storage? Bei Proxmox (der Host hat SSD) mit Windows 2008 R8 64Bit als VServer kommt ein sehr schlechtes Ergebnis raus: Bei VMware kommt bei der gleichen Hardware folgendes raus: Kann sich das For my main Proxmox I'm running a pair of 1. It looks like QD32 write looks bad. On 1 node, we add a dedicated SSD disk for Mysql, and use LVM to mount it in the VM. Hardware as bellow: - 2 sata SSD installed Promox VE 5. 768584] mpt2sas_cm0: High IOPs queues : disabled [ 5. According to the report, the test scale is 5 x Storage Server; Each Server 12HDD+3SSD, 3 x replication 2 x 10GbE NIC a. Specifically, per the Admin guide: For running VMs, IOPS is the more important metric in most situations. I tried changing filesystem to EXT4/ZFS and it was the same. 2% (17.
