xxvi IBM TotalStorage SAN Volume Controller: Installation Guide

Page 29

Attention: Static electricity can damage electronic devices and your system. To

avoid damage, keep static-sensitive devices in their static protective bags until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and possibly damage the

device.

v While the device is still in its anti-static bag, touch it to an unpainted metal part of

the system unit for at least 2 seconds. (This action removes static electricity from the package and from your body.)

v Remove the device from its package and install it directly into your SAN Volume

Controller, without putting it down. If it is necessary to put the device down, place it onto its static-protective bag. (If your device is an adapter, place it component side up.) Do not place the device onto the cover of the SAN Volume Controller or onto a metal table.

v Take additional care when you handle devices during cold weather because

heating reduces indoor humidity and increases static electricity.

SAN Volume Controller

The SAN Volume Controller is a SAN appliance that attaches open-systems storage devices to supported open-systems hosts.

The IBM TotalStorage SAN Volume Controller provides symmetric virtualization by creating a pool of managed disks from the attached storage subsystems, which are then mapped to a set of virtual disks for use by attached host computer systems. System administrators can view and access a common pool of storage on the SAN, which enables them to use storage resources more efficiently and provides a common base for advanced functions.

The SAN Volume Controller is analogous to a logical volume manager (LVM) on a SAN. It performs the following functions for the SAN storage that it is controlling:

v Creates a single pool of storage

v Logical unit virtualization v Manages logical volumes v Provides advanced functions for the SAN, such as:

– Large scalable cache – Copy services

Space management

–

- FlashCopy

(point-in-time copy)

- Metro Mirror (synchronous copy)

- Data migration

- Mapping that is based on desired performance characteristics

- Quality of service metering

Page 32

A node is a single storage engine. Figure 4 provides an illustration of a node. The storage engines are always installed in pairs with one to four pairs of nodes constituting a cluster. Each node in a pair is configured to back up the other. Each pair of nodes is known as an I/O group. All I/O operations that are managed by the nodes in an I/O group are cached on both nodes for resilience. Each virtual volume is defined to an I/O group. To avoid any single point of failure, the nodes of an I/O group are protected by independent uninterruptible power supply (UPS) 5115 or uninterruptible power supply (UPS) 5125 units.

Figure 4. A SAN Volume Controller node

The SAN Volume Controller I/O groups recognize the storage presented to the SAN by the backend controllers as a number of disks known as managed disks. The application servers do not recognize these managed disks. Instead they see a number of logical disks, known as virtual disks, that are presented to the SAN by the SAN Volume Controller. Each node must be in only one I/O group and provide access to the virtual disks in the I/O group.

The SAN Volume Controller helps to provide continuous operations and can also optimize the data path to ensure performance levels are maintained. Ensure that you use IBM TotalStorage Multiple Device Manager performance manager to analyze the performance statistics. See IBM TotalStorage Multiple Device Manager

Configuration and Installation Guide and IBM TotalStorage Multiple Device Manager CLI Guide for more information.

The fabric contains two distinct zones: a host zone and a disk zone. In the host zone, the host systems can identify and address the nodes. Yo u can have more than one host zone. Generally, you will create one host zone per operating system type. In the disk zone, the nodes can identify the disk drives. Host systems cannot operate on the disk drives directly; all data transfer occurs through the nodes. Figure 5 on page 3 shows that several host systems can be connected to a SAN fabric. A cluster of SAN Volume Controller nodes is connected to the same fabric and presents virtual disks to the host systems. Yo u create these virtual disks from units of space within a managed disk group. A managed disk group is a collection of managed disks presented by the back-end RAID controllers, providing a storage

pool. Yo u choose how each group is made up, and you can combine managed disks from different manufacturers’ controllers in the same managed disk group if required.

Figure 5. Example of a SAN Volume Controller in a fabric

You can remove one node in each I/O group from a cluster when hardware service or maintenance is required. After you remove the node, you can replace the field replaceable units (FRUs) in the node. All disk drive communication and communication between nodes is performed through the SAN. All SAN Volume Controller configuration and service commands are sent to the cluster through an Ethernet network.

Each node contains its own vital product data (VPD). Each cluster contains VPD that is common to all the nodes on the cluster, and any system connected to the Ethernet network can access this VPD.

Cluster configuration information is stored on every node that is in the cluster to allow concurrent replacement of FRUs. An example of this information might be information that is displayed on the menu screen of the SAN Volume Controller. When a new FRU is installed and when the node is added back into the cluster, configuration information that is required by that node is read from other nodes in the cluster.

Uninterruptible power supply overview

The uninterruptible power supply (UPS) provides the SAN Volume Controller with a secondary power source to be used if you lose power from your primary power

| | |

source due to power failures, power sags, power surges, or line noise. Two types of UPS units can be used with the SAN Volume Controller: the UPS 5115 and the UPS 5125.

If a power outage occurs, the UPS maintains power long enough to save any configuration and cache data contained in the dynamic random access memory (DRAM). The data is saved to the SAN Volume Controller internal disk. Figure 6 on page 16 and Figure 7 on page 16 provide illustrations of the two types of UPS units.

Page 46

Figure 6. Uninterruptible power supply 5125

Figure 7. Uninterruptible power supply 5115

Note: The SAN Volume Controller UPS is an integral part of the SAN Volume

Controller solution. It maintains continuous SAN Volume Controller specific communications with its attached SAN Volume Controller nodes. The SAN Volume Controller cannot operate without the UPS. The SAN Volume Controller UPS must be used in accordance with documented guidelines and procedures and must not power any equipment other than SAN Volume Controller nodes.

svc00001

To provide full redundancy and concurrent maintenance, the SAN Volume Controller must be installed in pairs. Each SAN Volume Controller of a pair must be connected to a different UPS. Each UPS 5125 can support up to two SAN Volume Controller

nodes. The UPS 5115 can support one SAN Volume Controller node. It is also

16 IBM TotalStorage SAN Volume Controller: Installation Guide

Page 47

recommended that you connect the two UPS units for the pair to different independent electrical power sources. This reduces the chance of an input power failure at both UPS units.

The UPS must be in the same rack as the nodes. Ensure that you are following the UPS guidelines that are provided in Table 1.

|||||

Number of uninterruptible

Number of nodes

2 2 2 4 2 4 6 4 6 8 4 8

power supply 5125 units

Number of uninterruptible power supply 5115 units

Attention:

1. Do not connect the uninterruptible power supplies to an input power source that does not conform to standards.

2. Each UPS pair must power only one SAN Volume Controller cluster.

UPS includes power (line) cords that connect the UPS to either a rack power

Each distribution unit (PDU), if one exists, or to an external power source. Each UPS power input requires the protection of a UL-approved (or equivalent) 250 volt, 15 amp circuit breaker.

The UPS is connected to the SAN Volume Controllers with a power cable and a signal cable. To avoid the possibility of power and signal cables being connected to different UPS units, these cables are wrapped together and supplied as a single field replaceable unit. The signal cables enable the SAN Volume Controllers to read status and identification information from the UPS.

Each SAN Volume Controller monitors the operational state of the UPS to which it is attached. If the UPS reports a loss of input power, the SAN Volume Controller stops all I/O operations and dumps the contents of its DRAM to the internal disk drive. When input power to the UPS is restored, the SAN Volume Controllers restart and restore the original contents of the DRAM from the data saved on the disk drive.

A SAN Volume Controller is not fully operational until the UPS battery charge state indicates that it has sufficient capacity to power the SAN Volume Controller long enough to permit it to save all its memory to the disk drive in the event of a power loss. The UPS has sufficient capacity to save all the data on the SAN Volume Controller at least twice. For a fully-charged UPS, even after battery capacity has been used to power the SAN Volume Controllers while they save DRAM data, sufficient battery capacity remains to let the SAN Volume Controllers become fully operational as soon as input power is restored.

Note: Under normal circumstances, if input power is disconnected from the UPS,

the SAN Volume Controller connected to that UPS performs a power down sequence. This operation, which saves the configuration and cache data to an internal disk in the SAN Volume Controller, typically takes about three minutes, at which time power is removed from the output of the UPS. In the event of a delay in the completion of the power down sequence, the UPS

Chapter 2. Overview of the uninterruptible power supply 17

Page 48

output power is removed five minutes after the power was disconnected to the UPS. Because this operation is controlled by the SAN Volume Controller, a UPS that is not connected to an active SAN Volume Controller will not shut off within the five-minute required period. In the case of an emergency, you must manually shut down the UPS by pushing the UPS 5125 power off

button, or the UPS 5115 on/off button.

| | |

Attention: Data integrity could be compromised by pushing the UPS 5125 power

off button or the UPS 5115 on/off button. Never shut down a UPS without first shutting down the SAN Volume Controller nodes that it supports.

It is very important that the two nodes in the I/O group are connected to different uninterruptible power supplies. This configuration ensures that cache and cluster state information is protected in the event of a failure of the UPS or mainline power source.

When nodes are added to the cluster, you must specify the I/O group that they will join. The configuration interfaces also checks the UPS units and ensures that the two nodes in the I/O group are not connected to the same UPS units.

Figure 8 shows a cluster of four nodes, with two I/O groups and two UPS 5125 units.
