    Understanding ceph performance and scaling

    Do not do that, it will lead to data loss. You need "mixed use" or "enterprise" SSDs and not "read intensive" or "consumer grade" SSDs. The latter perform worse than HDDs in heavy write situations. Ceph always writes randomly. Do not mix device classes in one pool. Separate SSD-OSDs and...

    Understanding ceph performance and scaling

    So I've been playing around in my lab to get ceph going on a 5 node cluster backed by a 10g network. I've setup 3 nodes to test ... each with one nvme and one hdd I've created two crushmaps, the default one and another targeting the ssd/nvme drives I've setup the corresponding pools and...

    Help needed > ZFS/storage setup with 3 NVMe and 1 SATA SSDs

    speed is not the problem, ZFS will wearout any consumer ssd, it require datacenter grade ssd with power protection. it's not suited for home lab.

    Onboard NVMe controller with ZFS (ZFS is not compatible with disks backed by a hardware RAID controller)

    Ideally, anything with Power-Loss-Protection (PLP), the cheapest ones are just below 300€ by now. With consumer SSDs it is always a bit hit or miss if they are decent enough. Consumer SSDs are optimized for a desktop workload, where they will see writes happening in short bursts and data...

    [Suggestions] 8HDD's + 5NVME's (Z2 or Raid10 or something else)

    I personally wouldn't do that. Special devices are no cache. Lose those special devices and all data on the HDDs ist lost too. And what is killing SSDs primarily are sync writes and thats the only thing the SLOG is doing. So by putting the SLOG on the same disk as your special devices, those...

    Nested virtualisation (filesystems) on zfs

    Hi there, So in building my home lab I've been generally pleased with the performance of windows and linux VMs despite using consumer grade nvme/ssd/ Most of my hosts contain a single SATA SSD and NVME of the same size. The plan was to have these setup as a mirror, knowing the SSD will drag...

    Rebuild my lab with ZFS

    Always depends on the workload. But yes, but to on the safe side you should better buy proper enterprise/datacenter grade SSDs with power-loss- protection and additional TBW/DWPD. Otherwise sync write performance will be really bad, continously writing stuff will casue massive performance drops...

    Help with designing a home cluster on consumer hardware

    Your post is fine. But is is complex. Too complex to generate a compact answer ;-) You have several hardware devices. In that case I wouldn't virtualize TrueNAS. This approach has several pros and cons... No. ZFS gives so many advantages! Data integrity check +, self-healing = reliability...

    Purchasing a Server Exclusively for PBS (hardware discussion)

    Hi All, We're looking to purchase a server new, explicitly for PBS. Which is a bit of a big commitment for us. So I thought I'd run the specs by everyone here in case I'm missing anything. . . SUPERMICRO AS-2124US-TNRP Server/Chassis 2 x 16 Core AMD EPYC 7313 Gen 3 Processor 256GB DDR4-3200...

    Help with designing a home cluster on consumer hardware

    ...again for learning/testing/demo A few questions I have if someone could please help me understand: I keep reading never to run consumer grade ssds with ZFS due to performance and poor lifespans. Taking performance off the table, should I be avoiding the use of ZFS mirrors for the pve local...

    Ext4 for my workload? Plus general questions.

    They start new at 42€, so not that expensive. If you don't want to buy a crappy QLC consumer SSDs, then its not that much more. Cheap Samsung Enterprise SSD for example maybe 25% more than a Samsung EVO consumer SSD. There will still be write amplification. In my benchmarks I for example have...

    Ext4 for my workload? Plus general questions.

    ...up LXCs of those programs to find out how they should be configured to work together. With how I am planing to use my setup: should I still expect high wear? Or is a consumer grade ssd fine since I am using ext4 (no write amplification) and don't plan on handling terabytes of data? Thanks!

    Help for fist time set up Proxmox

    Actually I'm planning use CCTV on this but my budget is also low. Sorry but I as my using also for test (Centreon, Zabbix, Grafana, Prometheus, graylog ..) for monitoring i think this will write a lot and i have read many topic that the ZFS will burn the ssd that why i though may be use VMs and...

    [TUTORIAL] If you are new to PVE, read this first; it might assist you with choices as you start your journey

    I don't say don't use ZFS in home environments. I just say get proper disks if you want to use it. See all the threads of people complaining about high IO delay and unusable write performance when using ZFS with QLC consumer SSDs. It always works like this: "Beginner: PVE is too slow!" "Me: Is...

    [TUTORIAL] If you are new to PVE, read this first; it might assist you with choices as you start your journey

    ANY disk can fail at any time, even enterprise grade. It could be your SSDs were living in a heat hostile environment. It could also be another 1000 reasons. My point is that ZFS is better than EXT4 even in RAID-Z0, for a variety of reasons. The fact that a single disk can fail is no reason to...

    Terribly slow mdraid with LVM

    Had not done secure erase before proxmox install . These are relatively new devices actually : I do understand these are consumer grade SSD but even in raid10, no zfs,its very bad. Is there any chance that my setup is of raid+lvm has some issue ?

    Terribly slow mdraid with LVM

    I got few server where have consumer grade SSDs, earlier was using ZFS but apparently apart of good amount of RAM, ZFS also need enterprise SSD with some inbuilt cache / fault protection. So I built next server with mdraid and LVM thin (for snapshot features). But my benchmarks are terribly...

    Recommended SSDs/M.2s for a non critical mini server system

    PLP will allow the SSD to run for a few seconds without power from the PSU so it can quickly dump all data from the volatile DRAM cache into the non-volatile SLC cache. This will allow the SSD to cache sync writes in DRAM cache and therefore heavy increase the sync write performance and heavy...

    Recommended SSDs/M.2s for a non critical mini server system

    Very good points in the linked post! Do you consider power loss protection (PLP) as also an important feature of server SSD drives? For example these consumer "data center" grade U.2 ssd drives have them: https://www.kingston.com/en/ssd/dc1500m-data-center-ssd...

    Recommended SSDs/M.2s for a non critical mini server system

    Wow! That is insane! Thank you so much for sharing. I thought no one produces MLC SSD drives now, due to high cost. So 30 DWPD basically means that you can re-write the whole capacity of the ssd drive 30 times per day, everyday for 5 years? Wow. Not even asking how much these drives cost. The...
