![]() ![]() My one big qualm with it is that it still has pretty crappy scripting support and we had to write our own Python wrapper over their scripting interface to make it work for our purposes. SAN/iQ 8 also supports forking of snapshots, and is a huge improvement< over the previous version. They also have a neat feature in that you can set up a virtual SAN appliance in a VMWare host and use it to migrate data between SANs without purchasing any special additional hardware. The LeftHand SAN/iQ software supports asynchronous replication as well as snapshots, and does both quite well. By having two, the setup effectively becomes a RAID 1+5. The LefHand units we have are configured in RAID 5, I don't know if the newer ones support RAID 6 or not but quite frankly I don't think we would use it even if they did. They handle the Virtual IP handoff of the SAN very well in a failover scenario. We only had a few crashes with earlier versions but the latest builds have been rock solid. ![]() On OS X we use GlobalSAN as the iSCSI initiator and it works extremely well. The SAN consists of a pair of HP D元20s in a mirrored failover configuration. We have 3 XServes that access the SAN, as well as about 10 Linux servers, some of which form a Xen cluster. We've been using a LeftHand iSCSI SAN for over two years now.
