EATURES

All models of the StorageWorks Enclosure 4300 Family have the following features:

• Ultra3 (LVD) support – Delivering data transfer rates up to 160 MB/s per channel

• 3U rack height

• Supports up to 14 (1-inch) Ultra3 Universal hard disk drives

• Provides storage capacity of up to 1TB per enclosure (using 72.8GB 1-inch disk drives)

• Modular design allows the StorageWorks Enclosure 4300 to be used in any storage configuration from JBOD (Just a Bunch of Disk) to Smart Array

storage enclosures to external RAID arrays. House up to 14 enclosures in one 42U rack for a single rack storage capacity of up to 14.2TB of disk

storage (JBOD configuration) or up to 12 enclosures in an EMA16000 (HSG80 configuration) for a single rack storage capacity of 12.2TB.

• A common storage platform allows for future storage consolidation to the SAN.

• Award-winning innovative SCA (Single Connect Attach) direct connect drive carrier - provides better cooling and reliability for 10K and 15K drives

• Hot pluggable disk drives, power supplies, and fans

• Redundant fans, redundant power supply and dual bus I/O module

(Each Enclosure 4314T and 4314R come with a single power supply that is sufficient to provide power to the enclosure and maintain normal

operating levels. A second optional redundant power supply is recommended for higher levels of fault tolerance and availability.)

• Environmental Monitoring Unit (EMU) – Monitors environmental conditions within the enclosure and components such as the power supply and

fans

• Easy removal of parts provides better serviceability. No tools are required!

IGHLIGHTS

Upgradability

Upgrading a StorageWorks Enclosure 4200 to a StorageWorks Enclosure 4300 is as easy as swapping out the I/O module on the back of the unit. The

I/O module is warm-swappable, therefore during the upgrade power to the unit can remain on, but all I/O operations need to be stopped to ensure that no

data is lost during the upgrade.

Mix and Match

All Ultra3 devices from Compaq are compatible with previous Ultra2 devices so customers can mix and match components in the same storage enclosure

or server. When Ultra2 devices and Ultra3 devices are found on the same Ultra3 SCSI bus, each Ultra2 device will transfer data up to 80 MB/s, while

each Ultra3 device will transfer data up to 160 MB/s.

Note: For customers who operate legacy Models 4310R and 4350R enclosures, the use of 1-inch Universal Ultra2 or Utlra3 disk drives requires the

addition of 0.6-inch drive extenders.

Hot Pluggable

Hot pluggable technology is designed into drives, power supplies and redundant cooling fans. Hot pluggable components can be replaced without

powering down the storage system or stopping I/O operations. This feature significantly enhances data availability.

Auto SCSI ID Selection

SCSI ID is automatically set when a drive is inserted into a drive bay.

LED Indicators

Front panel LEDs indicate drive activity, required drive service, and power, giving a quick visual assessment of overall system storage status. LED status

and fault indicators for the fans and power supplies are located in the back of the enclosure.
