1. 4/8 ports.
2. Support 2Tb+ drives.
3. RAID functionality is not important. Be sure that the system disks were presented separately.
In General, would be Intel SASUC8i
(about him you know that he is operating under diesel fuel), but there is a maximum of 2Tb disks.
Write good reviews about IBM ServeRAID M1015, but it is absolutely not clear where to take in SPb/MSK.
Happy to hear your advice.
