NUMA in i2 Servers

Socket 0 Socket 1

Socket 2 Socket 3

Scalable Blade Link

Each socket/processor has its ownmemory (local) Each Processor can access other

Processor Memory (remote) In one-blade or two-blade server,

every access at most one hop

Example: BL860c i2, BL870c i2 In four-blade server, the maximumwill be two hops

Example: BL890c i2

The new i2 Servers come with 5different memory configurations

helping customers to profile theirapplication needs accordingly Details are part of this White paper: Why

Performance Highlights

OpenVMS running on BL8x0c i2 servers

BL8x0c i2 servers architected for high performance

Architecture provides increased number and faster cores/socket

Superior memory and interconnect technology

Memory intensive applications benefit from low latency and high bandwidth architecture

Higher IO bandwidth and throughput resulting from new IO architecture

More headroom for CPU, Memory and IO intensive workloads with improved responsetime

Upto 2x performance improvement with i2 servers running OpenVMS

Our test have shown up to 2x improvement with java, some database and web serverapplications

Oracle has shown upto 3x improvement
