High Performance StorageWorks Disk Drives

HIGHLIGHTS

o  Low profile RZ28M replaces the RZ28-VA and the RZ28B-VA

o  Low profile RZ26N replaces the RZ26L-VA

o  Fits in StorageWorks deskside-to-datacenter enclosures

PRODUCT DESCRIPTION

Two new high performance StorageWorks disk drives are now available.

o  RZ28M -- the low-profile 5400 RPM, 2.1 GB, 3.5 inch SCSI disk drive
   replaces the RZ28 and RZ28B, and offers equivalent functionality,
   performance, and reliability

o  RZ26N -- the low-profile 5400 RPM, 1.05 GB, 3.5 inch SCSI disk drive
   replaces the RZ26L, at a lower price and a 50 percent improvement in MTBF

For maximum applications coverage, both drives are available in 8-bit narrow
and 16-bit wide variants.

With the introduction of this product family, Digital is moving to a single
part number for each major class of disk drives. This strategy eliminates
the confusion that results from multiple part numbers, and ensures the
availability of Digital-qualified, high-quality disk products.

BENEFITS

o  Designed to deliver unparalleled reliability, stability, performance, and
   data integrity

o  Flexibility to support systems from the desktop to the datacenter

o  Allows a choice of disk drives to meet performance and budget needs

o  Easy to install, configure, maintain, and hot-swap devices with modular
   StorageWorks carriers

o  Five-year warranty on all drives; first year onsite
