Today we announced a slew of new options for IBM NeXtScale System. We first announced NeXtScale last year, based on our experiences with iDataPlex and BladeCenter, for customers needing a dense and cost-effective “no frills” compute offering.
Today’s announcement adds a number of new additional capabilities to the solution and in this blog post, I’ll explain a few of them.
The most noticeable addition to NeXtScale is the new PCIe Native Expansion Tray. This 1U half-wide unit attaches to the nx360 M4 compute node and enables the use of two high-performance NVIDIA GPUs or Intel Xeon Phi coprocessors. This allows you to create an ultra-dense GPU/Phi node with up to two high powered accelerators attached to a single compute node within 1U effective rack density.

Intel Xeon Phi coprocessors are based on Intel Many Integrated Core (MIC) architecture and allow you to gain additional compute capacity with highly-parallel technical computing applications workloads, while maintaining a unified hardware and software environment.
NVIDIA GPUs enable high-performing scientific, engineering, financial, and enterprise applications. Application performance will be accelerated by offloading compute-intensive portions to the GPU, while the remainder of the code still runs on the CPU. From a user's perspective, applications simply run significantly faster.
Also announcing today are 12 additional Intel Xeon processor options ranging the low-core-count E5-2603 v2 processor (4 cores per processor) through to high core frequency models like the E5-2667 v2 processor (at 3.3 GHz). With this announcement you now have the flexibility to choose the Intel processor with the characteristics that best your workload type. Similarly we’re also offering 3 new RDIMM options, rounding out the memory choices to include some lower-cost single-rank and dual-rank 1600 MHz DIMMs.
We’ve also announced support for the ServeRAID M5120 RAID controller for external SAS storage expansion. With this adapter, you can now attach external disk enclosures such as the EXP2512 and EXP2524 for even greater direct-attach storage capacity.
On the chassis side, we’ve announced a new 80 PLUS Platinum-compliant 1300W power supply option and new models of the NeXtScale n1200 chassis that include this 1300W power supply as standard. With a choice between a 900W or 1300W power supply option, you don’t have to compromise between your need for compute power and your need for energy efficiency.
The NeXtScale n1200 chassis houses up to 12 compute nodes and
provides shared power and cooling
All in all, these newly announced options makes NeXtScale an even more flexible and cost-effective offering.
