Table 1-2 Features of the HS21 XM
1.2.2 BladeCenter LS21 server
The BladeCenter LS21 blade servers are high-throughput, two-socket, SMP-capable, AMD
Opteron-based blade servers. This two-socket AMD Opteron blade server is well suited to
HPC and other applications requiring high performance and high-speed fabrics.
The processors used in these blades are standard- and low-power, full-performance Opteron
processors. The standard AMD Opteron processors draw a maximum of 95 W. Specially
manufactured low-power processors operate at 68 W or less without any performance
trade-offs. This savings in power at the processor level combined with the smarter power
solution that BladeCenter delivers make these blades very attractive to clients who have
limited power and cooling resources.
The BladeCenter LS21 is a single-width blade server that offers these features:
򐂰 Up to two high-performance, AMD Dual-Core Opteron processors.
򐂰 System board containing eight DIMM connectors, supporting 512 MB, 1 GB, 2 GB, or 4
GB DIMMs. Up to 32 GB of system memory is supported with 4 GB DIMMs.
򐂰 SAS controller, supporting one internal SAS drive (36 or 73 GB) and up to three additional
SAS drives with optional SIO blade.
򐂰 Two TCP/IP Offload Engine-enabled (TOE) Gigabit Ethernet controllers (Broadcom
5706S) standard, with load balancing and failover features.
򐂰 Support for concurrent KVM (cKVM) and concurrent USB / DVD (cMedia) through
Advanced Management Module and optional daughter card.
򐂰 Support for Storage and I/O Expansion (SIO) Unit.
򐂰 Three year on-site limited warranty.
