• Active Memory Sharing is planned to be supported with the availability of SLES
11 SP1.
Customers can upgrade from PowerVM Express to either PowerVM Standard or
PowerVM Enterprise, or they can upgrade from PowerVM Standard to PowerVM
Enterprise.
By upgrading to PowerVM Standard or PowerVM Enterprise, users gain the ability
to create up to 80 logical partitions on the Power 710 or up to 160 logical partitions
on the Power 730. Users also gain the ability to manage their PowerVM enabled
machine with either an HMC or the Integrated Virtualization Manager.
By upgrading to PowerVM Enterprise, users can leverage Live Partition Mobility and
Active Memory Sharing.
I/O drawer availability
One disk-only I/O drawer is supported, providing large storage capacity and multiple
partition support:
• Feature 5886 EXP12S holds 3.5-inch SAS disk or SSD.
EXP 12S SAS Drawer (#5886)
The EXP 12S SAS Drawer (#5886) is a 2 EIA drawer and mounts in a 19-inch rack.
The drawer can hold either SAS HDDs or SSD. The EXP 12S SAS drawer has twelve
3.5-inch SAS disk bays with redundant data paths to each bay. The drawer supports
redundant hot-plug power and cooling and redundant hot-swap SAS expanders
(Enclosure Services Manager-ESM). Each ESM has an independent SCSI Enclosure
Services (SES) diagnostic processor.
The SAS HDDs or SSD contained in the EXP12S are controlled by one or two PCIe
or PCI-X SAS adapters connected to the EXP12S via SAS cables. The SAS cable will
vary, depending upon the adapter being used, the operating system being used, and
the protection desired.
• The large cache PCI-X feature 5904/5908 uses a SAS Y cable when a single port
is running the EXP12S. A SAS X cable is used when a pair of adapters are used
for controller redundancy.
• The medium cache PCI-X feature 5902 and PCIe feature 5903 adapters are
always paired and use a SAS X cable to attach the feature 5886 I/O drawer.
• The zero cache PCI-X feature 5912 and PCIe feature 5901 use a SAS Y cable
when a single port is running the EXP12S. A SAS X cable is used for AIX/Linux
environments when a pair of adapters is used for controller redundancy.
In all of the above configurations, all 12 SAS bays are controlled by a single
controller or a single pair of controllers.
A second EXP12S drawer can be attached to another drawer using two SAS EE
cables, providing 24 SAS bays instead of 12 bays for the same SAS controller port.
This is called cascading. In this configuration, all 24 SAS bays are controlled by a
single controller or a single pair of controllers.
The feature 5886 can also be directly attached to the SAS port on the rear of the
Power 710 or Power 730, providing a very low-cost disk storage solution. When
used this way, the imbedded SAS controllers in the system unit drive the HDDs in
EXP12S. A second unit cannot be cascaded to a feature 5886 attached in this way.
19-inch racks
The Model 8231-E2B and its I/O drawers are designed to mount in the 25U 7014-
S25 (#0555), 36U 7014-T00 (#0551), or the 42U 7014-T42 (#0553) rack. These
racks are built to the 19-inch EIA standard. When you order a new 8231 system,
you can also order the appropriate 7014 rack model with the system hardware on
