40 IBM Flex System V7000 Storage Node Introduction and Implementation Guide

2.1 IBM Flex System V7000 Storage Node overview

When virtualizing external storage arrays, an IBM Flex System V7000 Storage Node can

provide up to 32 PB of usable capacity. An IBM Flex System V7000 Storage Node supports a

range of external disk systems similar to what the IBM Storwize V7000 system supports

today. A control enclosure contains two control canisters; an expansion enclosure contains

two expansion canisters. Both of these enclosures can contain up to 24 disk drives of the 2.5

inch form factor.

The IBM Flex System V7000 Storage Node is a modular storage system designed to fit into

the IBM Flex System Enterprise chassis. When purchased in the IBM PureFlex

configurations, the IBM Flex System V7000 Storage Node is configured from the factory into

the hardware solution purchased. If, however, the configuration wanted is not offered in the

predefined offerings, then a “Build to Order” configuration is designed to meet your needs.

The IBM Flex System V7000 Storage Node includes the capability to virtualize its own

internal storage in the same manner as the IBM Storwize V7000 does. The IBM Flex System

V7000 Storage Node is built upon the software base of the IBM Storwize V7000, which uses

technology from the IBM System Storage SAN Volume Controller (SVC) for virtualization and

the advanced functions of the IBM System Storage DS8000 family for its RAID configurations

of the internal disks, and the highly flexible graphical user interface (GUI) of the IBM XIV

Storage Subsystem for management.

The IBM Flex System V7000 Storage Node provides a number of configuration options that

are aimed at simplifying the implementation process. It also includes automated instruction

steps, called

Directed Maintenance Procedures (DMP), to assist in resolving any events that

might occur. The IBM Flex System V7000 Storage Node is a clusterable, scalable, storage

system, and an external virtualization device.

The IBM Flex System V7000 Storage Node is designed to be a scalable internal storage

system to support the compute nodes of the IBM Flex System environment. It will contain a

control enclosure that contains a pair of clustered node canisters and accommodates up to

twenty-four 2.5-inch disk drives within the enclosure. Each control enclosure can additionally

attach a maximum of two IBM Flex System V7000 Expansion Enclosures that can reside in

the IBM Flex System Enterprise chassis with it.

Optionally, up to nine IBM Storwize V7000 Expansion Enclosures can be installed externally;

however, a total of no more than nine expansion enclosures using either IBM Flex System

V7000 internal Expansion Enclosures (maximum 2), IBM Storwize V7000 external Expansion

Enclosures (maximum 9), or any combination, are supported. With the configuration of a

single IBM Flex System V7000 Control Enclosure using twenty-four 1 TB 2.5" disks attached

to nine IBM Storwize V7000 Expansion enclosures, each using twelve 3 TB 3.5" disks, the

system can manage a raw capacity of 348 TB.

The IBM Flex System V7000 Storage Node can contain up to four control enclosures in a

cluster configuration, each supporting the full configuration described, resulting in a maximum

total raw capacity of 1392 TB.

The control enclosure can support the addition of up to nine IBM Storwize V7000 expansion

enclosures connected externally. The additional expansions allow for a total of 240 disk

drives; or for a maximum capacity of 348 TB supported per control enclosure.

Tip: For maximum capacity numbers, the 7026-212 expansion enclosure and 3 TB SAS

Nearline drives must be used.
