4.1 Planning overview

We start with an overview of the planning tasks required for the proper installation of IBM Flex
System V7000 Storage Node.

4.1.1 Hardware planning

Proper planning before the actual physical installation of the hardware is required. Here is an
overview of the requirements to use to plan your installation:
Each IBM Flex System V7000 Storage Node enclosure within the IBM Flex System
Enterprise Chassis uses four bays (double wide and double high). Make sure that you
have enough space in the chassis for the installation of IBM Flex System V7000 Storage
Node control and internal expansion enclosures.
IBM Flex System V7000 Storage Node control and expansion enclosures are attached in
a single redundant SAS chain. Each IBM Flex System V7000 Control Enclosure will
support up to nine expansion enclosures total, which constitutes an IBM Flex System
V7000 Storage Node.
IBM Flex System V7000 Control Enclosure supports the attachment for up to nine
Expansion Enclosures using either IBM Flex System V7000 Expansion Enclosures
(maximum 2), IBM Storwize V7000 Expansion Enclosures (maximum 9), or a combination
of both.
The IBM Flex System Enterprise Chassis contains 14 bays in total, so there can be at
most three IBM Flex System V7000 Storage Node enclosures (a control enclosure and up
to two IBM Flex System V7000 Expansion Enclosures). Any additional expansion
enclosures would have to be IBM Storwize V7000 expansion enclosures attached
externally to the same single SAS chain.
Tip: Installing a Flex System V7000 Enclosure within an Enterprise Chassis requires
the removal of some of the shelves within the chassis, which would normally support
the compute nodes.
Install the hardware as described in the IBM Flex System V7000 Storage Node Installation
Guide, GC27-4203.

system/storage_node/flex_system_v7000
Two separate power outlets are required from redundant power sources in the rack for the
two power cords included with each enclosure. From 2 to 20 outlets are required,
depending on the number of enclosures to install. The power cord connectors are IEC320
C13/C14 standard connections.
There are four optional configurations that can exist for host connections to IBM Flex
System V7000 Storage Node through network adapters. See Chapter 11, "SAN
connections and configuration" on page 457 for detailed examples of how to configure the
host connections.
