thx for the pointers:
Still the question remains how much speed advantage will it bring? is going from 13 to 30 MB/s or from 13 to 15?
First of all thank you for this great product!
I see you are recommending in your answers to add an ssd cache. Now I am not an expert on esxi maintenance (just a long time user) but how does this work.
My situation:
(2x) Poweredge r820 with 4 spinning disks in raid 10 and 4 ssd disks in raid 10, Of course Esxi only sees datastores because the ssd's are presented as single volume to esxi by the raid controller.
questions:
- I would like to buy an additional ssd for use as ssd cache how would I need to configure the raid controller?
- Any recommended size for an SSD cache?
- How to setup this SSD cache within esxi?
- Currently I get speeds of 13 MB/s (Onediff, initial backup) using 4 gigabit ports on each server, what can I expect of speeds after adding a cache ssd?
Regards Dave
