HP

HP AJ828A StorageWorks DAT 320 160/320GB External SAS backup drive

SKU CH-A4GC-GV0TC MPN AJ828A

External SAS tape drive storing 160 GB native or 320 GB compressed on DAT-320 and DAT-160 cartridges at 12 MBps native and 24 MBps compressed

  • Native 160 GB capacity stores full backups on one cartridge
  • Compressed 320 GB capacity doubles storage with hardware compression
  • 24 MBps compressed transfer rate completes jobs in half the time
  • 64 MB buffer smooths data flow during streaming writes
  • SAS interface connects directly to servers without extra controllers

HP StorageWorks DAT 320 external SAS tape drive

The HP AJ828A is an external backup drive that writes and reads DAT-320 and DAT-160 cartridges. It connects through a SAS interface and stores 160 GB native or 320 GB compressed per tape. A 64 MB buffer helps maintain steady streaming during long jobs.

Suited for small-server archives needing removable

Organisations that require offline, removable copies for compliance or air-gap protection will find the cartridge format practical. Environments that need random-access speed, very high throughput, or network-attached backup targets should consider disk- or cloud-based alternatives instead.

SAS interface dictates host compatibility

The drive ships with a SAS connection and requires a compatible host adapter or controller. Verify that the server or workstation has an available SAS port before purchase.

Questions sur cet article

How do I connect the SAS interface on the AJ828A to my server?

Use a standard SAS cable from the drive's external port to a compatible SAS HBA or RAID controller; the step often missed is ensuring the host bus adapter supports the DAT 320 recording standard before configuring the backup software.

Which tape cartridges will I need to replace over time for the AJ828A?

The drive reads and writes DAT-320 and DAT-160 cartridges; plan to replace media after the manufacturer's recommended pass count or if the drive reports write errors during verification.

What is the native throughput ceiling I will hit during a long backup job on the AJ828A?

Sustained native transfer tops out at 12 MBps with a 64 MB buffer; compressed throughput reaches 24 MBps (86 GBph) but only with compressible data.
