7 Hardware Products
The G06.26 RVU contains new features for these hardware products:
ESS XP12000
NonStop S-Series CO Servers
ESS XP12000
The XP12000 is the next generation of the Enterprise Storage System (ESS). All ESS
models (including XP128, XP1024, and XP12000) are supported on the G06.24 and
later RVUs. The XP12000 provides:
Higher scalability
Higher performance
External storage capability
Higher availability
Migration
Certain migration limitations exist for configurations that include XP12000 or I/O
adapter module (IOAM) enclosures. For a comprehensive list of these limitations,
contact your HP representative.
Restrictions for the XP12000 are the same as for previous models and include:
If you migrate data from a NonStop S-series system to an ESS and the data is
located on disks within I/O enclosures, these I/O enclosures must be populated
with I/O multifunction 2 (IOMF 2) CRUs.
Contractually, only ESS-trained technicians can handle or configure ESS
equipment. Therefore, to install, configure, or operate the ESS, ensure that the
ESS-trained technician is on site and available.
You can use an XP12000 as you did the previous models. You must:
Configure the storage array logical unit numbers (LUNs) and SCF to access them.
Use the new online data migration facility to move data to those LUNs.
Back up data from 514-byte sectored disks prior to data migration to ESS.
Retain a copy of the old CONFIG file in case you need to perform a release level
fallback.
The migration of existing data from internal SCSI-attached, 514-byte sectored disks to
industry standard, 512-byte sectored disk subsystems includes an improved method
for checksum protection. The new checksum protection method employed for
unstructured files requires that the data stored on disk be contiguous and aligned in
units of 28 KB. For partitioned unstructured files requirements for ESS, see the G06.24
