Appears as a disk subsystem providing LUNs toservers

These can be thin provisioned as of V4.3

Virtualizes IBM and non-IBM storage

Over 175 systems from EMC, Dell, HP, HDS, NetApp,Sun, Pillar, & STK)

Allows for standard multipath driver regardless ofbackend array

SVC engine

IBM System x3550 M3 server (1U)

Intel Xeon 5600 (Westmere) 2.53 GHz quad-core

processor

24GB of cache

Four 8Gbps FC ports each engine

2 x 10 Gb Ethernet ports support for iSCSI host

attachment 2 x 1Gb Ethernet ports for SSPC administration

Solid State Drive support

Up to 4 x 146GB SSD disks per engine(optional)

New engines may be intermixed in pairs with

other engines in SVC clusters

Cluster non-disruptive upgrade capability replace older engines

IBM System Storage


SVC 2145-CG8 engine based on IBM System x3550 M3 server (1U)

Intel Xeon 5600 (Westmere) 2.53 GHz quad-core processor 24GB of cache Four 8Gbps FC ports

Supports up to four internal 146GB SSDs

Optional 10 Gb Ethernet support for 10 Gb iSCSI host attachment and future FCoEsupport

Two 10Gb ports per storage engine Storage engine supports 10Gb iSCSI or internal SSDs but not both Factory install or nondisruptive field upgrade

Engines may be intermixed in pairs with other engines in SVC clusters

Mixing engine types in a cluster results in volume throughput characteristics of theengine type in that I/O group

Cluster non-disruptive upgrade capability may be used to replace older engines withCG8 engines

Replaces the SVC 2145-CF8 engine

SVC Advantages Industry-leading storage virtualization offering

Only storage virtualization system with integrated Real-time Compression designed to be

used with active primary data

Best performing storage virtualization system in industry-standard benchmarks

First storage virtualization system with fully integrated SSD support

Integrated iSCSI server attachment support and support for FCoE protocol

Fully upgradable without disruption from smallest to largest configurations

Future proof with ability to replace current hardware with new hardware without disruption

Network-based virtualization with SVC supports diverse server environments including

VMware, other virtualization, and non virtualized servers

IBM has shipped over30,500 SVC engines running in more than 9,300 SVC systems

From 2006 to present, across this entire installed base, SVC delivered better than five

nines (99.999%) availability

SAN Volume Controller is a proven offeringthat has been delivering benefits to customers

for over eight years

SAN Volume Controller can virtualize IBM and non-IBM storage (over 130 systems from

IBM, EMC, HP, HDS, Sun, Dell, NetApp, Fujitsu, NEC, Bull)
