IBM Flex System V7000 Storage Node Introduction and Implementation Guide
2.1 IBM Flex System V7000 Storage Node overview
When virtualizing external storage arrays, IBM Flex System V7000 Storage Node can provide
up to 32 PB of usable capacity. 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.
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,
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.
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. 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.
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. IBM Flex System V7000 Storage Node is a clusterable, scalable, storage system, and
an external virtualization device.
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 thereof, are supported.
Note: Maximum capacity can be reached by either raw capacity or total number of drives:
1. With the configuration of a single IBM Flex System V7000 Control Enclosure using
twenty-four 1 TB 2.5" disks attached to nine external IBM Storwize V7000 Expansion
enclosures (2076-212); with twelve 3 TB 3.5" SAS Nearline drives installed in each
2076-212, the system can manage a raw capacity of almost 353 TB.
2. 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 raw capacity of 288 TB supported per control
enclosure each with 24 drive expansion enclosures (2076-224) with 1.2 TB drives.
3. 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 1412 TB.
