Hello,
We have a MD3220i SAN with 12 600GB 10K RPM drives. 1 is hot fail and the rest 11 are setup in 2 gorups of RAID 5.
Am planning to another 12 to increase the size. options are 600GB or 900GB.
- Will there be any issues if I add 12 900GB drives in RAID10?
- If I add 12 600GB drives, can the existing hotfailover drive be a "cover" for the rest 23? My worry is that since I am adding the 12 at a later time, they might be slightly different than the existing 12.
- I have got a quote from yobitech which is cheaper than dell's. They claim that since these are for the MD series which require a special firmware, their drives are OEM and not just compatible drives. Will appreciate any input on this.
Thanks
