MD1000 Dell PowerVault 15-Bay SAS and SATA Expansion Enclosure

The Dell PowerVault MD1000 is a modular disk storage expansion enclosure for PowerEdge servers. It houses up to fifteen 3.5-inch hot-pluggable disk drives in a single 3U rackable chassis, and the direct-attached enclosure takes both Serial Attached SCSI and Serial ATA drives, which can be mixed in the same enclosure.

A Dell MD1000 works with a host-based PowerEdge RAID controller (PERC). With a PERC 6/E, up to three 15-drive enclosures, 45 drives in total, can be daisy chained to a single host connection, which reaches 90TB with 2TB drives. The drives can also be split between two servers. PERC 5/E supports RAID 0, 1, 5, 10 and 50, while PERC 6/E adds RAID 6 and 60, with up to 30 physical disks per group and up to 256 virtual disks.

Drive options include 15K rpm SAS drives from 73GB to 600GB, 10K rpm SAS drives in 300GB, 400GB and 600GB, nearline SAS at 7,200 rpm in 500GB, 750GB and 1TB, 7,200 rpm SATA II from 250GB to 2TB, and energy-efficient 5,400 rpm SATA II in 1TB and 2TB. Capacity per enclosure ranges from 1.1TB with fifteen 73GB drives to 30TB with fifteen 2TB drives. The drive carrier is a common one that can be used on select Dell servers.

Each of the one or two hot-pluggable management modules has one x4 3Gb SAS (SFF 8470) host connector and one x4 3Gb SAS (SFF 8470) expansion connector. Each power supply provides 478 W continuous (550 W peak) on 100-240 V input at 47-63 Hz, and the chassis measures 13.11 cm high, 44.63 cm wide and 48.01 cm deep. Drives, power supplies and cooling modules are hot-pluggable.
