Benefits |
|
|
|
|
Modular system delivering leadership performance efficiency |
|
- Ultra-slim and powerful blade design delivers high density without sacrificing server processor performance.
- Smarter design can substantially reduce power consumption per blade compared to competitive 1U/blade offerings, potentially yielding better performance/watt.
- Easily add or change blades without disrupting the operation of other blades installed in the chassis.
|
|
|
|
|
Supports up to two Dual-Core Intel Xeon Processors with up to 1333 MHz front-side bus with a shared 6 MB L2 cache |
|
- The shared 6 MB L2 cache provides better performance for both single and multi-threaded applications
- Access to larger cache means faster data access and improved performance of content creation and entertainment applications
- Equipped with Intel Hyper-Threading technology, the Intel Xeon Processor delivers server performance ideal for compute-intensive, next-generation network and IT application workloads.
|
|
|
|
|
Supports up to two Quad-Core Intel Xeon Processors with up to 1333 MHz front-side bus with a shared 2x6 MB (12 MB) L2 cache |
|
- Delivers ultimate processor performance with eight cores using larger and better optimized 12 MB L2 cache
- Maximize multi-threaded applications for faster and concurrent execution
|
|
|
|
|
Up to 16 GB Fully Buffered DIMM internal memory with 4 GB DIMM support |
|
- Fully Buffered DIMM memory delivers better memory bandwidth and reduced latency over DDR II resulting in better application performance
- Error checking and correction offer high performance with mainframe-inspired fault protection.
- Expandable to 8 DIMMs (up to 32 GB) with Memory and I/O Expansion Unit
|
|
|
|
|
64-bit extensions |
|
- The HS21 blade features the Intel Xeon Processor supporting Intel Extended Memory 64 Technology
- Provides 64-bit addressability while supporting both 64- and 32-bit applications, allowing for a smooth transition to 64-bit enabled applications while leveraging the price and performance of existing applications.
|
|
|
|
|
Support for up to five hard disk drives (HDDs) |
|
- The HS21 supports two internal small form factor 10,000rpm SAS HDDs.
- Optional three hot-swap 2.5" SAS HDDs with Storage and I/O blade (SIO)
- The SIO also allows you to add an optional RAID-5 controller with battery-backed cache
|
|
|
|
|
Integrated dual Gigabit Ethernet connections |
|
- The TCP/IP Offload Engine (TOE) capable NICs are enabled to transmit large amounts of data at fast speeds for high-performance network applications.
- Robust design supports teaming and failover.
- These NICs will also support RDMA and iSCSI via a software key (availability is planned)
|
|
|
|
|
Two high-availability midplane connections |
|
- Provides durable and reliable connections to all chassis resources.
|
|
|
|
|
Blade server interconnects |
|
- Supports an optional 2-port (up to 4 Gb per port) Fibre Channel Expansion Card (Host Bus Adapter) to deliver a high-performance, highly manageable storage area network (SAN).
- Supports an optional 2-port Gigabit Ethernet Expansion Card to enable additional Ethernet bandwidth and allow for connection to multiple LAN segments.
- Supports an optional iSCSI Expansion Card for a lower cost storage option
- Supports up to four PCI-Express connected high-speed fabrics, including 4X InfiniBand.

|
|
Light path diagnostics standard |
|
- Provides quick and easy guide to troubleshoot your server for higher availability and system uptime.
- Independently powered, allowing you to remove the server from the chassis and still illuminate the light path LEDs.
|
|
|
|
|
Predictive Failure Analysis (PFA) |
|
- Helps save you time and money by decreasing planned and unplanned downtime.
- Helps increase uptime by allowing you to receive proactive alerts as much as 24-48 hours in advance.
|
|
|
|
|
Integrated System Management Processor |
|
- Increases server availability by continuously monitoring your system and notifying you of potential system failures or changes.
|
|
|
|
|
IBM Director and IBM Director Extensions comprehensive systems management tools |
