A REFERENCE GUIDE FOR OPTIMIZING DELL™ SCSI SOLUTIONS
3. Dell's Product Offering
PowerVault™ 220S & 221S Storage Enclosure
Dell™ PowerVault 220xS systems are flexible, external SCSI expansion enclosures
designed to support multiple Dell storage environments and RAID configurations. Each
system offers maximized drive-spindle count, hot-plug hard drives, optional redundant
power, redundant cooling, rack mount capability, systems management features, and a
modular design for easy upgrades. Most major components, including hard drives and
power supply/cooling modules are hot-pluggable and can be removed and replaced
easily.
The PV22xS is available as two model types: the PV220S which fits within an industry
standard 19 inch rack, and the PV221S which is a free standing floor tower. Both models
leverage the same base mechanical frame, but differ with respect to the mounting
hardware and front bezel features. Dell offers a conversion kit to change from a PV220S
to a PV221S. Basic features and options common to both models are shown in Figure
3-1.
