I’m currently testing the beta of the new Starwind version 5.9
New Features and Improvements:
- High Aavailability
Three active nodes for more availability.
- Replication to remote iSCSI Target over WAN as an experimental feature.
- Data deletion support. Unused data blocks are overwritten by new actual data.
- 30% less memory usage (2MBs per 1GB of deduplicated storage on 4kb deduplication block).
- coming soon! Backup Plug-in for ESX virtual machines
Installing the same configuration on 2 VMware VM’s (both 1CPU, 2048MB Memory and 2x VMXNET3 card)
2 NICS are required to use HA / High Available Disk Devices
I used 2 Virtual Disks. One for OS, and one for iSCSI Volumes.
Next add your license key to the management interface. and finish installation on both servers.
Create a new iSCSI image disk on both servers during the wizard. (second disk on VM) I used the full disk size.
selected the Sync and heartbeat network and click Next
Make sure you have enough space left on your second disk, this generated the error.
I run the wizard again and created a smaller 50Gb LUN, this succeeded.
the 2 nodes are Synchronizing the block data now.
I added both iSCSI server nodes as a iSCSI target all ESX hosts.
After Synchronization the lun’s became visible on my ESX hosts
looks like two of my paths are still there, looks good.
Turned the server back on, and all my paths are back up again.
I will test this iSCSI SAN performance on my local lab SSD raid 0 set in my next post this week.
