Today I have a QNAP TS-859U+ with 8 X 2TB disks in it.
As it's was setup on day-1 it uses a single volume on a raid 5.
The volume has currently a mixture of:
- 2 shared folders
- 5 iScsi Targets - of which
- 1 is a 1TB datastore to a VMware ESXi5
- 3 are LUNs in a W2K8R2 and are the used for the company as the network folders (Management, QA, RD...)
- 1 is LUN for an SQL database server - holding all DB files
The total used storage I have is <5TB so I don't mind rebuilding a single Raid10 on the NAS (even consider the Raid10 + hot spare)
- Should I divide the volumes into 2 seperate ones?
- How big should they be?
- on one volume assign to my VM Datastorate
- on 2nd volume give to my network?
- for my network, should I use a single large iScsi ? or keep the same small splits
I will appreciate any RTFM links, as I couldn't find the right answers (maybe I am asking the wrong question)
- I can not say that we have high number of reads or writes - but I don't know if I can measure that (count new files?)
- I am able to use a backup NAS for the transition (of which I will need a plan of how to make that transition work)
