LSI Firmware VSAN
I’ve been talking to LSI over the past couple months in relation to VSAN and have a couple updates on issues and thoughts.
1. LSI support does not support their driver if it is purchased through an OEM. They will not accept calls from VMware regarding this driver in this case either. If you want LSI to support the VMware driver stack, you must buy direct from them.
2. LSI branded MegaRAID cards do not support JBOD (I understand that it is on the roadmap). Dell and others are offering alternative firmwares that allow this, but they have no comment or support statement on this.
3. MegaRAID CLI can be used with RAID 0 to manage cards (i’ll release a guide if there is interest) and performance is comparable and on supported systems is very stable. Don’t rule it out, and with all the back and forth on support for JBOD it strangely might be the safer until I get full testing reports from the Perc730 next week.
4. The Dell Perc730 has JBOD support now. Despite being a MegaRAID I’m hearing good things in the field so far (I’ll update if I hear otherwise).
5. LSI prefers dealing with hardware vendors, and largely being a back end chip-set manufacturer. A stronger relationship with VMware is needed (especially with PCI-Express networking on the horizion).
6. HP is switching to Adaptec for controllers. Hopefully this should bring their JBODs onto the VSAN HCL and allow for supplier diversity.
7. I’ve heard statements from Dell that VMware is intensifying the testing procedures for VSAN. It looks like this will catch H310/2208 type issues first.
