Notes:
1. 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 8843-01Y is 8843-01U. See
the product-specific Official IBM announcement letter for other country-specific GAV model numbers.
GAV to MTM mapping for A.P. Geographies follow the same pattern. Substitute the last character with a
country-specific designator.
2. Intel Xeon processor with Extended Memory 64 Technology (EM64T), L2 cache and an 800MHz (quad-
pumped) Front Side Bus (FSB).
3. High-speed, two-way interleaved PC2-3200 RDIMMs. Maximum capacity requires replacing the
standard DIMMs. Memory-mirroring, hot-spare memory and Chipkill functions are supported. Chipkill
is available on DIMMs 512MB and greater.
4. System management functionality, interconnect network connectivity and console connectivity are
managed through the standard management module. The standard integrated service processor
monitors HS20 - 8843 system management activity, communicating with the management module in the
BladeCenter.
5. Dual Broadcom 5704S Gb Ethernet controllers.
6. An integrated, single-channel, Ultra320 SCSI controller supports integrated RAID-1 and 1E. RAID-1E
requires the optional BladeCenter Storage Expansion unit.
7. Maximum internal storage capacity is based on installation of two 146.8GB SCSI HDDs.
8. An optional BladeCenter expansion unit is available that attaches directly to the blade server adding two
hot-swap SCSI HDD bays for a total of four HDD bays and two expansion card slots for a total of three
expansion card slots.
9. Model 27Y hardware components come preconfigured and the Microsoft Windows Server 2003
operating system is pre-installed. One 2Gb fibre channel small form factor expansion card is standard.
10. HS20 Storage Server operating system supports a maximum of 4GB of memory.
