HP SSD Over Provisioning Optimisation

[Craig_W]

In the process of setting up new HP servers for S2D, OS being installed on SSD's (RAID1) and I have the option to enable or disable SSD Over Provisioning Optimisation - my thoughts are this should be enabled (if I understand correct this will further increase lifespan). Can anybody confirm?

 

The SSDs are 2x 800GB

What's the DWPD, and how much will you write per day?

 

If they're nodes in a cluster why use raid 1? Isn't S2D doing node level RAID anyway?

[Craig_W]

The RAID1 is the 2 SSDs for the OS, then no RAID on the data drives for S2D cluster - does that not seem correct to you?

Oh, that's fine then. If you're just running the hyper-v role not going to get many writes anyway I'd guess, so doesn't matter either way.

 

What are you using for the s2d cluster network btw?
