1.1 IBM Storwize V5000 Gen2 overview

The IBM Storwize V5000 Gen2 solution is a modular entry-level and midrange storage solution. The IBM Storwize V5000 Gen2 includes the capability to virtualize its own internal Redundant Array of Independent Disk (RAID) storage and existing external storage area network (SAN)-attached storage (the Storwize V5030 only).

The three IBM Storwize V5000 Gen2 models (Storwize V5010, Storwize V5020, and Storwize V5030) offer a range of performance scalability and functional capabilities. Table 1-1 shows a summary of the features of these models.

change

The IBM Storwize V5000 Gen2 addresses the block storage requirements of small and midsize organizations. The IBM Storwize V5000 Gen2 consists of one 2U control enclosure and, optionally, up to ten 2U expansion enclosures on the Storwize V5010 and Storwize V5020 systems and up to twenty 2U expansion enclosures on the Storwize V5030 systems. The Storwize V5030 systems are connected by serial-attached Small Computer Systems Interface (SCSI) (SAS) cables that make up one system that is called an

I/O group.

With the Storwize V5030 systems, two I/O groups can be connected to form a cluster, providing a maximum of two control enclosures and 40 expansion enclosures. With the High Density expansion drawers, you are able to attach up to 16 expansion enclosures to a cluster.

The control and expansion enclosures are available in the following form factors, and they can be intermixed within an I/O group:

򐂰 12 x 3.5-inch (8.89-centimeter) drives in a 2U unit 򐂰 24 x 2.5-inch (6.35-centimeter) drives in a 2U unit 򐂰 92 x 2.5-inch in carriers or 3.5-inch drives in a 5U unit

2 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1

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.

Important: For more information about supported environments, configurations, and restrictions, see the IBM System Storage Interoperation Center (SSIC):

For more information, see this website:

http://www.ibm.com/support/knowledgecenter/STHGUJ/

The IBM Storwize V5000 Gen2 is a virtualized storage solution that groups its internal drives into RAID arrays, which are called the Storwize V5030 systems by importing logical unit numbers (LUNs) from external FC SAN-attached storage. These MDisks are then grouped into created from these storage pools and provisioned out to hosts.

managed disks (MDisks). MDisks can also be created on

storage pools. Volumes are

Storage pools are normally created with MDisks of the same drive type and drive capacity.

Vo l um 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 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 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.

1.2 IBM Storwize V5000 Gen2 terminology

The IBM Storwize V5000 Gen2 system uses terminology that is consistent with the entire IBM Storwize family and the IBM SAN Volume Controller. The terms are defined in Table 1-2. More terms can be found in Appendix B, “Terminology” on page 819.

Table 1-2 IBM Storwize V5000 Gen2 terminology

IBM Storwize V5000 Gen2 term Definition

Battery Each control enclosure node canister in an IBM Storwize V5000

Gen2 contains a battery.

Chain Each control enclosure has either one or two chains, which are

used to connect expansion enclosures to provide redundant connections to the inside drives.

Clone A copy of a volume on a server at a particular point. The

contents of the copy can be customized and the contents of the original volume are preserved.

Control enclosure A hardware unit that includes a chassis, node canisters, drives,

and power sources.

Data migration IBM Storwize V5000 Gen2 can migrate data from existing

external storage to its internal volumes.

Distributed RAID (DRAID) No dedicated spare drives are in an array. The spare capacity is

distributed across the array, which allows faster rebuild of the failed disk.

IBM Storwize V5000 Gen2 term Definition

Managed disk (MDisk) A component of a storage pool that is managed by a clustered

system. An MDisk is part of a RAID array of internal storage or a SCSI LU for external storage. An MDisk is not visible to a host system on the SAN.

Node canister A hardware unit that includes the node hardware, fabric, and

service interfaces, SAS expansion ports, and battery. Each control enclosure contains two node canisters.

PHY A single SAS lane. Four PHYs are in each SAS cable.

Power Supply Unit Each enclosure has two power supply units (PSU).

Quorum disk A disk that contains a reserved area that is used exclusively for

cluster management. The quorum disk is accessed when it is necessary to determine which half of the cluster continues to read and write data.

Serial-Attached SCSI (SAS) ports SAS ports are connections for expansion enclosures and direct

attachment of hosts to access the IBM Storwize V5000 Gen2.

Snapshot An image backup type that consists of a point-in-time view of a

volume.

Storage pool An amount of storage capacity that provides the capacity

requirements for a volume.

Strand The SAS connectivity of a set of drives within multiple

enclosures. The enclosures can be control enclosures or expansion enclosures.

Thin provisioning or thin provisioned

Traditional RAID (TRAID) Traditional RAID uses the standard RAID levels.

Volume A discrete unit of storage on disk, tape, or other data recording

Worldwide port names Each Fibre Channel port and SAS port is identified by its

The ability to define a storage unit (full system, storage pool, or volume) with a logical capacity size that is larger than the physical capacity that is assigned to that storage unit.

medium that supports a form of identifier and parameter list, such as a volume label or input/output control.
