2.1.3 Older supported products
Older supported disk products which are no longer sold by HP include the DS2100, DS2110,
DS2300, SC10, HVD10, HASS, and AutoRAID 12H.
The DS2100 and DS2110 are 4-slot Ultra160 SCSI disk enclosures in a 1U form factor with
hot-swappable disks. They support Ultra320 disks and HBAs provided that the HBA is
configured to operate at Ultra160 speeds (see the footnote regarding this in Section 2.1.2). As
with the DS2120, up to three of these enclosures can be daisy-chained on a single bus to
provide increased storage.
The DS2300 is a 14-slot Ultra160 SCSI high-availability disk enclosure with hot-swappable
drives, power supplies, fans, and bus control cards (BCCs). Redundant power supply/fan
modules and BCCs can be removed and replaced without interrupting storage operations. As
mentioned above, the MSA30 is designed to be a replacement for the DS2300. As discussed
in Sections 6.1.3 and 6.2, standard HP-UX Diagnostics utilities can be used for enclosure
management of the DS2300, and centralized management of multiple DS2300s is available via
the Command View utility. See Section 5 for information regarding the use of the DS2300 in
HA configurations.
The SC10, HP’s SureStore E Disk System SC10, is a high-availability10-slot Ultra2 LVD SCSI
disk enclosure with hot-swappable drives, power supplies, bus control cards, and cooling fans,
and supports 10K and 15K rpm drives. Data throughput is limited to 40 MB/s due to an
internal SCSI SE backplane.
The HVD10 is a 10-slot Ultra2 HVD SCSI disk enclosure with hot-swappable components, and
supports 10K and 15K rpm drives.
The HASS is an 8-slot Fast/Wide High Availability Storage System (HASS) of hot-swappable
disk and/or tape drives, which can contain either HVD or SE devices.
The AutoRAID12H is a Fast/Wide HVD SCSI enclosure which continually fine-tunes itself for
maximum performance and data availability, keeping the most frequently accessed data in
RAID 0/1 storage, and less frequently accessed data in RAID 5 space. It supports active/active
controllers with hot fail-over, and a mirrored cache, keeping a complete copy of the cache on
both controllers.
The DS2300, HVD10, and SC10 also support an optional split bus mode which allows the
enclosure to be configured into two separate SCSI buses.
All of these older devices are supported on 11.0 and 11i v1. Only the DS Series products and
the SC10 are supported on 11i v2.
2.1.4 DVD+RW
The HP StorageWorks DVD+RW drive, the Q1592A product, is an Ultra2 SCSI LVD half-height
array module designed for use in the Tape Array 5300 discussed in Section 2.2.1 below. It
allows the customer to backup data and to install software to/from CD or DVD disks if the server
itself does not have a CD or DVD drive, or if additional DVDs or CDs are desired. A single
Tape Array 5300 could, for example, be used to house up to four DVD+RW drives, each
connected to a separate server or all four connected to one server. The DVD+RW supports a
wide variety of DVD and CD formats with up to 4.7 GB capacity in DVD formats, and up to
700 MB capacity in CD formats.
