StorageWorks HSD30 Array Controller

HIGHLIGHTS

o  Increases DSSI storage connectivity and extends I/O performance with
   RAID 0 (striping) standard and optional read cache in 16 or 32 Mbyte
   capacities

o  Provides connectivity for up to 21 industry standard SCSI-2 Digital
   storage devices

o  Supports host based volume shadowing (RAID 1)

PRODUCT DESCRIPTION

The new StorageWorks HSD30 Array Controller (SPD 53.53.01) provides
additional bus connectivity for storage devices and meets user requirements
for an open, scalable storage solution that incorporates advanced
performance and availability options, including a failover capability for
the attached storage devices.

Using only one node on the DSSI bus, each HSD30 Array Controller enables
storage connectivity for up to 21 Digital SCSI-2 devices, while using the
same industry standard StorageWorks devices and packaging that are supported
across a growing number of Digital and non-Digital platforms. To provide
balanced I/O performance, HSD30 based RAID 0 and read cache can also be
utilized.

Key HSD30 features:

o  High capacity -- Scalable solutions provide up to 44 Gbytes of disk
   storage on a single DSSI bus address and over 176 Gbytes per bus for
   single-host configurations.

o  High performance -- Controller based Raid 0 is standard on the HSD30,
   increasing performance in both throughput- and bandwidth-intensive
   environments. Optional read cache in 16 and 32 Mbyte increments is
   supported, providing significant improvements in subsystem latency for
   many applications. The high internal performance of the HSD30 supports
   I/O-intensive environments with request rates of up to 1000 I/Os per
   second and a bandwidth of 3.0 Mbytes per second.

o  High availability/performance -- For systems needing high availability,
   the HSD30 supports host based volume shadowing. For configurations
   needing redundancy, users can order device shelves, controller shelves,
   and various StorageWorks enclosures with redundant power options. The
   HSD30 can also be configured in high availability redundant
   configurations providing controller failover on the same DSSI bus.

o  StorageWorks compatibility -- A wide choice of Digital StorageWorks disk,
   tape, solid state disk, and optical devices permits users to configure
   storage subsystems to their exacting applications. StorageWorks
   controller compatibility allows for shadowing of like disk devices
   between HSD30 and HSJ30/40 controllers.

BENEFITS

The StorageWorks HSD30 Array Controller provides improved, user configurable
solutions, including:

o  Increased connectivity over competing offerings.

o  Greater device selection -- Support for the widest choice of storage
   devices with the widest range of direct and sequential access
   technologies and higher maximum capacities.

o  Better performance, complementing the high performance controller
   platform.

o  High speed device buses supporting maximum data rates of 10 Mbytes per
   second.

MIGRATION

Users with supported processor platforms can add the HSD30 subsystems via
embedded (SHAC) adapters or optional DSSI adapters. Supported StorageWorks
SCSI-2 storage devices also can be migrated from the HSZ10, HSC/K.SCSI, HSJ,
and HSD05 series of subsystems.

AVAILABILITY AND ORDERING

The StorageWorks HSD30 Array Controller is available now through the
DECdirect service, local Digital sales offices, and Digital's business
partners. The HSD30 models, storage enclosure components, and storage
devices are available on a configure-to-order basis for customized
application or storage demands. See the StorageWorks configuration guides
for detailed information.

TECHNICAL DATA

Supporting up to 18 storage devices in redundant controller subsystems and a
maximum of 21 devices for single HSD30 configurations, the HSD30 DSSI array
controller can draw on the same StorageWorks power and packaging options as
the HSJ series of subsystems. It is housed in the standard BA350-MA/MB shelf
for SW500 and SW800 series enclosures, with up to two controllers per shelf
for redundancy and failover on the same DSSI bus. In the SW500/SW800
enclosures, device shelf connection is provided with three independent SCSI
cables.

Initially, the following devices are being supported on the HSD30:

                             Solid
        Disk                 State
        Drives    Tapes	     Disks    CDROMs

        RZ26      TLZ06      EZ51R    RRD42
        RZ26L     TLZ06L     EZ54R    RRD43
        RZ28      TZ86       EZ58R    RRD44
        RZ28B     TZ87/N
                  TZ867
                  TZ877

The SW800 datacenter cabinet supports up to 18 building block shelves and
four controller shelves. The SW500 cabinet can hold a total of 10 shelves,
including one or two controller shelves.

The HSD30 controller comes with HS Operating Firmware V1.5. With this
version of the firmware, a maximum of four HSD30s is being supported per
DSSI bus, along with HSD05s, RF series disks, and TF series tape devices.

The HSD30 Array Controller is supported with limitations on OpenVMS VAX
V5.5-2 and later and on OpenVMS AXP V1.5 and 6.0. These limitations consist
of a lack of ERF (Error Reporting Format) and related translations support.

The supported OpenVMS VAX processors are the VAX 4000, 6000, 7000, and
10000. The supported OpenVMS AXP processor is the DEC 4000.
