1.will it work with ESXi5? Cloudstack release note says VMWare vSphere 5.0 has been fully supported since version 3.0.1.
2. does CloudStack support SAN (IB SRP) shows up as a san SCSI device in vmware. Again i cant find any definitive answers in the docs? I think yes, though I've never tried IB device before. But as long as VMware can format it as VMFS, you can add it as primary storage in cloudstack by choosing VMFS protocol.

So will it work with ESXi5? I don't see any specific statements saying it will in the docs? 2Nd San Vs ISCSI or NFS I have infiniband 40GB QDR SAN from Quantastor (www.osnexus) who ive been working with this last year to integrate Infiniband into the SAN (uses Ubuntu) so we now have a SRP Infiniband SAN, which also does iSCSI so the issues lately have been ESXi 5 and 4 Drivers for SRP. There is no SRP driver for ESXi5. But there is a new Infiniband (IB) driver which supports IP or IPOIB. I now have ESXi 5 working with IB ISCSI and can easily get 14GB/s i can transfer 5GB of data on a VM to VM @450-500MB/s in 25 seconds. so its quite fast. But not as fast as SRP Using SRP i easily get 32GB/s on ESXi4. (quad path MPIO) (yes GB for those reading! not Gb/s) so i can zip data round really quickly especially Vmotions etc. I have 2 SAN head units (12 x 1TB WD VR) in each. in Raid 5 and they happily spit out. pushing 10GB of data to and from, takes a mere 40-50 seconds. The problem is i want to use ESXi5 now not 4. SRP is still a little unstable. By that i mean some times there are connection issues with the IB Bus and vmware takes 1-2 mins to rescan/connect to Luns. Also when using clustered Storage for VCenter clusters, the nodes occasionally drop the Lun access and have to be restarted to reconnect to IB SAN. this isnt a problem with ISCSI ive noticed. But in production cloud it would be if nodes just dropped storage randomly. So 3rd Question.! does CloudStack support SAN (IB SRP) shows up as a san SCSI device in vmware. Again i cant find any definitive answers in the docs? Im thinking i will run SRP for Ubuntu management servers and internal VCenter and VM's so i get max speed with Vmotions etc. and run the cloud nodes on ESX5 with IB_ISCSI until Mellanox and VMWare come up with a SrP driver for esxi 5 any thoughts or comments would be usefull.
