Spec updated (first post) and images added. Now 21TB instead of 30TB of SAS drives. No more 32GB DOM. Throwing in Supermicro SSD trays, brand new spare fans etc.
Looking to clear quick so looking for any sensible offers (especially if collecting) will be happy to accept. Can ship UK wide too...
Been using Nakivo for coming on 3 years now on vSphere 6, 6.5+. Simple vSphere cluster with two ESXi hosts, two FreeNAS datastores, vSphere server.
Nakivo for us has been about £250 per annum with email support which is excellent on the few occasions we’ve had to use it.
The product is light...
Had two boards fail within two months of each other.
One an A1SRi-2758F (8 core) lasted almost 6 years, the other an A1SRi-2558F (4 core) lasted just shy 3 years.
Interestingly enough the 8 core arrived with a cooling fan in the server. The 4 core had no cooling fan. When we queried this the...
@Saoclyph system has only 9 drives now, we borrowed one to stick in another server. I can always drop a SATA drive in instead so it’ll have 9x SAS and 1x SATA.
I’ll look up shipping to France tonight. Can you PM me your address or something nearby so I can get an accurate quote before letting...
Upgrading parts of my homelab and doing some storage tests using sysbench:
sysbench --test=fileio --file-total-size=64G prepare
sysbench --test=fileio --file-total-size=64G --file-test-mode=rndrw --max-time=300 --max-requests=0 run
sysbench --test=fileio --file-total-size=64G cleanup
I did some testing using a Samsung EVO 250GB SSD.
ext4 - created using default partition tools on install:
read, MiB/s: 7.11
written, MiB/s: 4.74
zfs - ashift 9 - created using zpool create /dev/sda:
heheh @efschu2 all this faffing around with ZFS does make a simple ext4 volume seem the obvious and simplest choice, especially if using it for a homelab.
I'm a tinkerer so I'll test all the scenarios. I'll setup Proxmox to boot off the SSD SATA bay which will allow me to mess around with...
Heheh thanks @arglebargle, going from Intel S3700 drives for SLOG on a dedicated enterprise grade Supermicro server with a RAID 10 pool to this little NUC thing is definitely a learning experience.
Seems a single drive ZFS 'pool' should ideally have property `copies=2` set?
thanks all, there will be nightly backups to a Synology. It’s a home server so nothing critical.
The disk will be a single 1TB SSD. It will only have about 100-200GB of containers on it.
Do you know if ZFS on Linux’s lack of support for TRIM will be a problem?
Thanks @fossxplorer good advice - looking forward to playing with the NUC. I'm retiring a Nehalem Xeon based ESXi server. Can hardly believe how much processing power a NUC contains.
I'm messing around with Proxmox inside a VM at the moment and noticed it has RAID1 and RAID0 available for a...
Just picked up an Intel Coffee Lake NUC. I've ordered a single M.2 NVMe SSD (1TB Samsung 970 Evo Plus).
Wanted to run a few test VMs at home on it, nothing critical.
Would ZFS be the best filesystem to use or would XFS/ext4 be better?
Use NFS and beware of performance with Synology Hybrid RAID if running more than a couple of VMs - it has poor IOPs. Use RAID 10 and ideally a SSD write cache. Might be able to use SHR + cache just fine.
