The Bottom Line

The HS20 offers maximum bang for the buck by incorporating outstanding features in a tiny package:

Performance:

•Fast processor clock rates — Up to two 3.8GHz single-core 64-bit (EM64T) Xeon processors

•Low-voltage processor clock rates — Up to two low-voltage 2.8GHz single-core 64-bit (EM64T) Xeon processors

•Dual-core processors — Up to two 2.0GHz dual-core 64-bit (EM64T) Xeon processors

•Fast front-side bus — 800MHz FSB

•Large cache — 1MB or 2MB of L2 processor cache

•Fast memory — 400MHz PC2-3200 DDR II ECC memory

•Fast disk technology — Internal Ultra320 SCSI or SAS storage (2 HDDs), with the option for two additional SCSI HDDs in an adjacent storage blade (4 HDDs) total

•Fast I/O —InfiniBand, Myrinet or Fibre Channel connectivity via an optional expansion card

•Fast communications — Integrated dual Gigabit Ethernet, with the option for two additional Gigabit Ethernet ports via an expansion card (total 4 per blade)

Flexibility:

•Large memory capacity — 16GB using four 4GB DIMMs

•High-capacity disk storage — Up to 146.8GB of internal Ultra320 SCSI storage, with the option for two additional SCSI HDDs in an adjacent storage blade (4 HDDs, 746.8GB total)

•Integrated RAID — RAID-1mirrored arrays standard; enhanced RAID-1Earrays optional (using a SCSI storage expansion unit)

•One available adapter slot standard —

‰One legacy slot for standard HS20 adapters, or

‰One SPF slot for new HS20 adapters

•Additional optional adapter slots —

‰Two SFF slots provided by the SCSI Storage Expansion Unit6

‰Two standard PCI-Xslots provided by the PCI I/O Expansion Unit II7

Manageability and Availability:

•IBM Director systems management software

•Integrated mini-Baseboard Management Controller (mBMC):

‰IPMI 1.5 compliance, including highly secure remote power control

•Interface to one or two Management Modules or Advanced Management Modules in the BladeCenter chassis for advanced systems management capability

‰Supports LDAP and SSL industry standards

6The SCSI Storage Expansion Unit requires an adjacent blade slot.

7The PCI/I/O Expansion Unit requires an adjacent blade slot.
