| Feature | | Benefits |
|
|
|
| Modular system delivering raw processing power |
| - Ultra-slim and powerful, blade design delivers high density without sacrificing server processor performance.
- Up to 84 servers in an industry-standard rack or up to 80 in a telecommunications industry-standard, 84-inch rack, packing more performance per square foot and saving you valuable central office and/or data center real estate.
- Easily add or change blades without disrupting the operation of other blades installed in the chassis.
|
|
|
|
| Supports up to two AMD Opteron processors |
| - Support for single-core processors up to 2.80GHz as well as dual-core processors up to 2.40GHz.
- AMD Opteron processors offer an Integrated Memory Controller that allow for increased bandwidth and reduced latency for certain applications.
- BladeCenter supports lower-power versions of these full-performance AMD Opteron processors. These 68W processors draw up to 1/3 less power than the standard 95W AMD offering
- Supporting both 64- and 32-bit applications allows for a smooth transition to 64-bit enabled applications while leveraging the price and performance of existing applications.
|
|
|
|
| Up to 16GB of DDR memory |
| - 4 DIMM slots per blade
- Supporting a VLP (very low profile) DDR DIMM to maximise the amount of memory that can be installed in the ultra-dense blade.
|
|
|
|
| 64-bit extensions |
| - 64-bit addressability while supporting both 64- and 32-bit applications, allows for a smooth transition to 64-bit enabled applications while leveraging the price and performance of existing applications.
|
|
|
|
| Support for up to two internal hard disk drives (HDDs) |
| - The LS20 blade supports a pair of Ultra320 SCSI non-hot-swap HDDs in a choice of capacities—36GB or 73GB.
- Design allows users to keep both drives even when installing a SFF I/O expansion card.
|
|
|
|
| Integrated dual Gigabit Ethernet connections |
| - Enabled to transmit large amounts of data at fast speeds for high- performance network applications.
- Robust design supports teaming and failover.
|
|
|
|
| Two high-availability midplane connections |
| - Each blade is reliably and easily connected via two redundant paths to the passive midplane and the integrated switching and power infrastructure contained in the BladeCenter chassis.
|
|
|
|
| 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 |
| - Helps save you time and money by decreasing planned and unplanned downtime.
- Increases 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 |
| - Exploits hardware capabilities by surfacing pertinent information about your system, allowing you to automate a response.
- Helps increase uptime, reduce costs and improve productivity via advanced server management capabilities.
- Provides intelligent system management for rock-solid reliability.
- IBM Remote Deployment Manager simplifies and automates deployment and redeployment for efficient installation and startup.
