One straightforward way to improve the value of an HP 3000 is replacement. That is, finding a better disk storage hardware component—replacing what shipped with your 3000 with a corresponding disk subsystem, one that offers the superb protection of hardware RAID (Redundant Array of Inexpensive Disks).
I would also recommend this replacement for those who utilize HP 3000 Mirror/iX software—since Mirror/iX does not protect the MPEXL_SYSTEM_VOLUME_SET volume set . It also forces one to utilize user volume sets even if the situation does not otherwise warrant it. I believe there is a place for user volume sets, but only in very specific and limited circumstances.
The main advantage of hardware RAID is that it offers excellent protection from disk failures and resulting data loss and time lost due to data recovery requirements. Chances are good that you are if you are a candidate to benefit from hardware RAID, your existing disk technology is relatively old and prone to failure as a result of years of use.
Let's face it, unlike a good wine, older HP 3000 hardware and its associated peripherals do not get better with age. Quite the contrary.
However, even if you choose a RAID technology that is also relatively old or obsolete, the nature of the technology itself affords you a great measure of protection from disk failures and corresponding data loss and downtime.
The inexpensive choices include the Nike Mod10 or Mod20 and the HP Autoraid 12H. A higher-end RAID solution is in HP’s VA7000 family of products.
