DDR2 ECC Memory
The HS20 ships with 400MHz PC2-3200 double data rate II (DDR2) dual-interleaved memory
DIMMs for fast access. It supports up to 16GB of memory in four sockets, using industry-
standard ECC (Error Checking and Correcting) registered DIMMs. It supports optional Chipkill
3
ECC technology (using 1GB or larger DIMMs), for up to 16X better error correction than
standard ECC memory.
PC2-3200 memory is available in 512MB, 1GB, 2GB, 4GB and 8GB memory kits (two 256MB,
512MB, 1GB, 2GB or 4GB DIMMs per kit, respectively). DIMMs are installed in pairs for
increased performance provided by dual-interleaving.
Large HDD Storage Capacity
The HS20 offers a choice of disk storage, supporting up to two 2.5-inch internal fixed Ultra320
drives.
• 10K RPM 2.5-inch — 36.4 or 73.4GB capacities (146.8GB maximum)
If this is not enough internal storage, an optional “sidecar” storage blade is available. The SCSI
Storage Expansion Unit is a 30mm blade that supports up to two 3.5-inch hot-swap Ultra320
SCSI HDDs. It is installed in the slot adjacent to an HS20 blade server.
• 10K RPM 3.5-inch — 73.4, 146.8 or 300GB capacities (600GB maximum)
Fully populating both the HS20 blade and the expansion unit provides up to 746.8GB of local
storage to the HS20 blade server. If the customer needs more storage space, terabyte
capacities are possible with optional external SAN storage solutions.
External Tape Storage
The HS20 supports various external rack-mounted SAN-attached tape drives. Supported tape
technologies include:
• IBM 2U Universal Tape Autoloader
• IBM 4U Universal Tape Library
Gigabit Ethernet Controller
The HS20 includes an integrated Broadcom 5704 dual-port Gigabit Ethernet controller for up
to 10X higher maximum throughput than a 10/100 Ethernet controller. The integrated controller
offers failover and load balancing for better throughput and system availability. It also supports
highly secure remote power management using IPMI 1.5, plus Wake on LAN
®
and PXE
(Preboot Execution Environment) Flash interface.
Adapter Slots
The HS20 includes one PCI-X adapter slot on each blade. Either one legacy BladeCenter
expansion card or one SFF (small form factor) BladeCenter adapter can be installed in this
slot.
Adapters can be used to add interfaces to BladeCenter communication modules, including Fibre
Channel, Myrinet, additional Gigabit Ethernet modules, InfiniBand, etc. Using an SFF adapter
allows the use of both internal SCSI HDDs. Using a legacy card limits the number of usable
internal HDDs to one.
The SCSI Storage Expansion Unit provides two additional adapter slots for SFF/legacy cards.
(The first card must be a Gigabit Ethernet card.)
The optional PCI I/O Expansion Unit II provides two additional slots for standard PCI-X
adapters.

All models require optional Chipkill-enabled DIMMs for Chipkill protection. The DIMMs shipped with the systems are not Chipkill-
enabled. Chipkill memory is designed to detect and correct single- and multibit errors. Reliability improvements depend on many
factors and may be less than the maximum stated.
