- Model numbers provided are worldwide generally available
variant (GAV) model numbers which are not orderable as listed
and need to be modified by country. The U.S. GAV model numbers
use the following nomenclature: xxU. For example, the U.S.
orderable part number for 8850-51Y is 8850-51U. See the
product-specific Official IBM announcement letter for other
country-specific GAV model numbers. GAV to MTM mapping for
AP Geographies follow the same pattern. Substitute the last
character with a country-specific designator. - The LS20 blade server installs in a BladeCenter chassis and
ships without a keyboard and mouse. Up to fourteen AMD Opteron
LS20 for BladeCenter blade servers can be installed in a
BladeCenter E chassis (8677-3XX), 8677-1XX, 8677-2XX) at full
density once it has been upgraded with the new 2000-watt power
supply option. In addition, these new LS20 blade servers can
be installed in the BladeCenter T (8720-1RX and 8730-1RX). - Withdrawal dates are provided for U.S. and Canada only. Business
Partner Inventory may be available. - AMD Opteron processor is designed for high-performance workstation
and server applications. Provides three high-performance HyperTransport
links to I/O, as well as a 128-bit high-performance DDR SDRAM memory
controller. - Memory is two-way interleaved, PC-3200 CL3 ECC DDR2 RDIMM
supporting Chipkill technology. - The standard integrated service processor monitors LS20 system
management activity, communicating with the management module in
the BladeCenter. - Dual Broadcom 5704S Gigabit Ethernet connections with teaming
and failover support - An integrated, single-channel, Ultra320 SCSI controller supports
integrated RAID-1. - Maximum HDD storage capacity is based on installation of two 73.4GB
10K rpm Ultra320 SFF SCSI HDD. - Installing a legacy form factor I/O expansion card may prevent
installation of a second SCSI HDD. - This machine type includes dual core AMD Opteron Processors and
has 1MB per processing core.
