Specifications
HP J3293A SureStore HD Server 4000
with 18-GB Drives
A new model of HP SureStore HD Server 4000 has been added to
the three described in the User's Guide. The product number
HP J3293A contains six replaceable 18.2-gigabyte HP SCSI hard
disk drive modules, five preconfigured as a RAID 5 volume, one as a
hot spare.
With the sixth drive used as a spare (you can add it to the volume
instead), the capacity is approximately 4 times 18 GB, or 72 GB
(since RAID 5 uses the equivalent of one drive for redundancy).
Note this capacity calculation if you add a tape drive as described in
chapter 8 in the User's Guide. In other respects, it operates as
described for the other models in the User's Guide and Quick Setup
mat.
See appendix C in the User's Guide (and page 10 in this Addendum)
