Smartcache writeback Perfromance

[slimfatso]

Hello,

I'm upgrading my current server ( ML 560 g9) and i though about using smartcache with writeback to improve overall server perfromance. Unfortunatelly there is not enough data on hpe pages / and google .

I wonder whether anyone here is using this tech ? 

I though about this setup ( for sql server )

22 x 10k SAS raid 10 ( p440ar 2GB controller) 

2x800G ( raid1) SAS SSD MU As smartcache writeback.

Thank you.

Hello,

Please Try enabling Smart Cache after Disabling SSD Smart Path.

For SSD Drives, HPE has HP SSD Smart Path, which is a  newer technology that HP introduced for Smart Array controllers during the Gen8 lifecycle and is continuing to refine as part of Gen9 Storage. It is designed specifically to deliver performance gains for logical drives using Solid State Drives (SSDs) on HP Smart Array controllers.

You can enable HP SSD Smart Path on a volume by volume basis using HPSSA. Smart Path will not run in conjunction with FBWC or HP Smart Cache enabled and is not designed to operate with HDD-based Volumes.
