Looking for some guidance on placement of transaction logs. We have VM Ware with Fiber attached SAN storage. The disk and controllers are fully redundant.
We're looking to keep databases and transaction logs separated mainly for performance. Multiple databases will share the same database VMDK disk. However, for the transaction logs, would it be better for the corresponding sets of logs to share a VMDK log disk together or create individual VMDK disks for each set of database logs?
On one hand, having multiple sets of transaction logs in subfolders on a single large VMDK disk would allow them to share the space available and simplify the configuration. On the other hand, is it better to keep the logs isolated, each set on their own VMDK disk so that one filling up (or becoming corrupted in some way) won't affect the others?
Not sure it matters if these are VMDK disk or not but mainly wanted to get feedback on the idea of separation of the logs into their own disks.
Also, we are aware that VMDK disk is not fully supported on NAS based disk. This isn't NAS, it's FC attached SAN. Any known support issues there?
Thanks!
