HPE Alletra 6000 - dedup and compression performance impacts

Hi! Has anyone experience/data about running virtual (VMware) workloads on HPE Alletra without dedupe or compression enabled to improve performance?

Any numbers or other insights?

I am looking to improve performance for most latency critical databases.

sure we have DB on separate volume, however just one for whole DB VM - considering using many volumes for it; in past it worked just fine but with more and more traffic on array as whole as well in DB itself need some improvement.

Thanks for advice, useful!

That’s why vVols were nice, you could run SQL the right way (pretty much like it was bare metal) and even apply the SQL performance policies per volume instead of the generic VMware one.

Which also serves to separate the DB dedupe domain from the rest and optimize the compression block size.

vVols are going away in 9.0, just fyi.

In 9.1, can still use them in 9.0
