Chapter 1. Overview of the IBM Storwize V5000 Gen2 system 3
Two canisters are in each enclosure. Control enclosures contain two node canisters, and
expansion enclosures contain two expansion canisters.
The IBM Storwize V5000 Gen2 supports up to 1,520 x 2.5 inch drives or 3.5 inch drives or a
combination of both drive form factors for the internal storage in a two I/O group Storwize
V5030 cluster.
SAS, Nearline (NL)-SAS, and flash drive types are supported.
The IBM Storwize V5000 Gen2 is designed to accommodate the most common storage
network technologies to enable easy implementation and management. It can be attached to
hosts through a Fibre Channel (FC) SAN fabric, an Internet Small Computer System Interface
(iSCSI) infrastructure, or SAS. Hosts can be attached directly or through a network.
The IBM Storwize V5000 Gen2 is a virtualized storage solution that groups its internal drives
into RAID arrays, which are called
managed disks (MDisks). MDisks can also be created on
the Storwize V5030 systems by importing logical unit numbers (LUNs) from external FC
SAN-attached storage. These MDisks are then grouped into
storage pools. Volumes are
created from these storage pools and provisioned out to hosts.
Storage pools are normally created with MDisks of the same drive type and drive capacity.
Vo lum e s can be moved non-disruptively between storage pools with differing performance
characteristics. For example, a volume can be moved between a storage pool that is made up
of NL-SAS drives to a storage pool that is made up of SAS drives to improve performance.
The IBM Storwize V5000 Gen2 system also provides several configuration options to simplify
the implementation process. It also provides configuration presets and automated wizards
that are called
Directed Maintenance Procedures (DMP) to help resolve any events that might
occur.
Included with an IBM Storwize V5000 Gen2 system is a simple and easy to use graphical
user interface (GUI) to enable storage to be deployed quickly and efficiently. The GUI runs on
any supported browser. The management GUI contains a series of preestablished
configuration options that are called
presets that use commonly used settings to quickly
configure objects on the system. Presets are available for creating volumes and IBM
FlashCopy® mappings and for setting up a RAID configuration.
You can also use the command-line interface (CLI) to set up or control the system.
