IBM BladeCenter LS42

Vendor's description: Meeting today's cost challenges while planning for tomorrow’s growth can be difficult. With the new IBM BladeCenter® LS42 blade server get an affordable, scalable 2-processor blade server that you can easily upgrade to four processors as your business grows.

The LS42 blade server features the latest AMD Opteron processors for industry-leading performance. Supporting high memory capacity 16 DIMM slots and memory speeds up to 800 MHz, the LS42 can help drive your most demanding memory-intensive workloads such as virtualization, databases and high performance computing (HPC) applications.

The LS42 blade server offers an energy-efficient design along with low-voltage processors, integrated memory controller and available solid-state drives to help keep power consumption down and reduce cooling demands in your data center. When workloads demand more performance, this blade server is ready to scale to four processors with the addition of a multi-processor expansion unit (MPE). Simply snap the MPE to the original blade and it becomes a 4-processor, 60 mm blade server with the additional performance you need.


  • Maximize performance and minimize costs; consolidate workloads and virtualization on an energy-efficient platform that supports up to four AMD Opteron™ six-core processors or quad-core processors.
  • Pay as you grow; start with a 2-processor blade and upgrade to a 4-processor blade when ready without scrapping your initial investment.
  • Save time and money; standardize on a single platform for both 2- and 4-processor server application needs.
