General Storage Enclosure Guidelines

MD1000 – 3U/15 3.5” Hard Drive Enclosure

The MD1000 is a storage expansion enclosure housing up to 15 3.5-inch hard drives in 3U of rack
space. With its use of higher capacity 3.5” hard drives and its ability to support both high
performance SAS drives as well as low cost/high capacity SATA drives, the MD1000 is the general
purpose, capacity focused expansion enclosure in the Dell portfolio.

MD1120 – 2U/24 2.5” Hard Drive Enclosure

The MD1120 is a storage expansion enclosure housing up to 24 2.5-inch hard drives in 2U of rack
space. With its use of 2.5” hard drives that consume less space and use less power than 3.5” hard
drives, the MD1120 is the transactional performance focused expansion enclosure in the Dell
portfolio.
