Hello all, here is my build :
- CPU : intel Q6600
- Mobo : ASUS P5E
- RAM : 8 Gb GSkill
- Power : Corsair 750 Modular
- System drive : 1x OCZ SSD 120 Gb
- Data drive(s) : 16x Seagate Barracuda 2Tb 7200rpm in a MDRAID RAID6
- HBA : intel SASUC8I + intel Expander RES2SV240
- Management Network : integrated Marvell NIC
- Storage network : Dual 10GbE SFP+ intel NIC (x520-da2)
- OS : OMV4 (previously OMV3)
- Case : Norco RPC-4224
System is used to present LVM volumes via NFS to a VMware ESXi 6.5 cluster.
Previous limitations (resolved by recent actions) :
Network bottleneck on storage side (2x intel 1Gbit/s NIC) replaced by dual SFP+ 10GbE NIC
Current limitations/problems :
BIOS loses settings after power loss (motherboard bug, battery is ok)
intel SASUC8I is known to be unstable when using SMARTD. SMARTD currently disabled.
intel SASUC8I doesn't support drives over 2Tb.
Can't seem to go over 40-50% of 10GbE bandwisdth. Could be due to a PCIe lanes limitation
Next upgrade :
Replace SASUC8I with IBM/LSI M1015
Thoughts :
Back in the days I used Openfiler + iSCSI + ESX 4. I then discovered that except for SCST, IET doesn't support SCSI-3 reservations and therefore is no-go for more recent versions of ESXi. I now stick to NFS without issues.
Maybe I'll change my mobo+CPU someday (more power, less consumption)
Conclusion : Very happy of OMV !!
