What kind of NIC is installed on the HP host? Also what's going to be used as a target for backups?Backups with be Network Mode via a seperate Physical Backup host with replications during the day (to a 2nd ESXi host with DAS)
Since SSD cache stores the data that is accessed most frequently, I suspect that most part of the data that has been written to cache might be useful during backup session however that's just an assumption and should be tested in a lab. Also if not the source will be a bottleneck during backup session then SSD cache won't be helpful for backup performance at all.Do I have to be careful about flushing the SSD cache prior to backups? Is there anything to be mindful of?
That could be dangerous if you used volatile memory without BBU and chose write-back caching policy - in this case you could lose cached data if the powerloss occurred and no flush took place. Regarding the absence of data on the primary sotrage (HDD) - HP SmartCache is a controller based solution thus it manages data integrity on a hardware level, providing a transparent access to .vmdk data so I don't expect any problems with backups.I am more wanting to know if Veeam will capture valid backups, considering that potentially some data could be in the write cache and not actually layed down onto the disks?
