Intel announced a new Xeon server technology code named Nehalem EX on 30 March 2010. This is an important addition to the x86 portfolio, adding significant scalability to servers using this processor chip. With Intel Nehalem EX, IBM will continue to differentiate our software value for capacity priced (PVU) products based on two key attributes: performance and scalability.
These processor chips are available with 4, 6, or 8 cores per socket. The per core performance for this new chip has significantly improved relative to prior generation Xeon processors. Additionally, and for the first time, Xeon processor cores have near linear scalability, i.e. performance per core does not decline with the number of sockets and cores per server increasing up to 8 sockets and 64 cores. The Processor Value Units (PVUs) requirements for Intel Xeon Nehalem EX will be set at three different tiers corresponding to the scalability of the server. For servers with a maximum of 2 sockets per server possible, the processor cores on this server will require 70 PVUs per processor core. For servers with a maximum of 4 sockets per server, 100 Processor Value Units (PVUs) per processor core are required. And lastly, for servers with a maximum of 8 sockets per server, 120 PVUs per processor core are required.
These PVU requirements reflect both the performance and the scalability available on these new Xeon based systems (code named Nehalem EX). Customers using IBM software on these systems should see significant increases in their software price/performance over the systems they are likely to replace.
PVU licenses required for previous generation Intel Xeon multi-core processor technologies remain unchanged. With this announcement IBM continues the practice of licensing to the processor core. This practice provides the licensing granularity customers require while offering the flexibility to configure their systems to best support their business objectives.
