- the screenshots could be bigger, at the current size they are a bit difficult to decipher
thank you for that feedback

- are you saying that you add the iSCSI targets (quorum, sqldata, logs and back) to both installed server clusters?
The targets need to be added to all nodes that will use them. In this case the 2 node cluster will support failover for a SQL Server instance, so both nodes need to have the LUNs unmasked

- would you need to enable iSCSI MCS (multiple connections to same target/lun?)
MPIO may be a better option, i didnt go into this fully as this tutuorial is designed to ease the reader in to clustering gradually

with VMWare I recently made an interesting observation. If you do not presize your virtual disk and attempt to create a 10GB LDF (MS SQL Log File) on such a virtual hard disk performance will be very high and on the host system the VMDK will not really consume the 10GB. When using a preallocated VMDK disk performance will be considerably slow/normal.Best,

For the NAS data drives i use pre allocated virtual disks. LUNs are then created on the pre allocated drives.
Glad you enjoyed the article
