Page 27: Array Controller Card
Note – All Sun StorEdge T3+ array disk drives in a workgroup or in an enterprise configuration must have the same storage capacity and drive speed. Array Controller Card The Sun StorEdge T3+ array has a specific controller card that contains slightly different features on the exterior and a different design on the internal controller board.
Page 28: Figure 1-5 Sun Storedge T3+ Array Controller Card And Ports
The Sun StorEdge T3+ array controller card contains the RAID controller hardware and firmware, including: One Fibre Channel-Arbitrated Loop (FC-AL) port that uses an LC small-form factor (SFF) connector. The fiber-optic cable that provides data channel connectivity to the array has an LC-SFF connector that attaches directly to the port on the controller card.
Page 29: Unit Interconnect Cards (Uic)
Unit Interconnect Cards (UIC) The interconnect cards are alike on both array models. Each card has two interconnect ports: one input and one output for interconnecting multiple arrays. The interconnect card provides switch and failover capabilities, as well as an environmental monitor for the array.
Page 30: Figure 1-7 Interconnect Cards (Rear View)
The interconnect card contains the interface circuitry and two connectors for interconnecting multiple arrays. It provides loop-switch capability and contains an environmental monitor for the array. See . For information on how to FIGURE 1-7 service the interconnect card, see Chapter 14. Interconnect card 2 Interconnect card 1 Interconnect Cards (Rear View)
Page 31: Power And Cooling Unit
Power and Cooling Unit The power and cooling unit contains a power supply, two cooling fans, an integrated uninterruptible power source (UPS) battery, and LED status indicators for AC power.

Page 38: Enterprise
Enterprise An enterprise configuration has a master controller unit and an alternate master controller unit. In all default enterprise configurations, the master controller unit is the array positioned at the bottom of an array stack in either a rack-mounted or tabletop installation.
Page 39: Configuration Guidelines And Restrictions
Configuration Guidelines and Restrictions Workgroup Configuration Restrictions The media access control (MAC) address is required to assign an IP address to the controller unit. The MAC address uniquely identifies each node of a network. The MAC address is available on the pull-out tab on the front left side of the array. A host-based mirroring solution is necessary to protect data in cache.
Page 40: Configuration Recommendations
Configuration Recommendations Use enterprise configurations for controller redundancy. Use host-based software such as VERITAS Volume Manager (VxVM), VERITAS Dynamic Multipathing (DMP), or Sun StorEdge Traffic Manager for multipathing support. Connect redundant paths to separate host adapters, I/O cards, and system buses. Configure active paths over separate system buses to maximize bandwidth.
Page 41: Sun Cluster Support
Sun Cluster Support The Sun StorEdge T3+ array is supported in Sun Cluster configurations with the following restrictions: Array controller firmware version 2.0 or later is required on each Sun StorEdge T3+ array. Sun Cluster 3.0 environments support the Sun StorEdge T3+ array. Enterprise configurations are supported only in Sun Cluster 3.0 environments.

Page 137: Post-Installation Global Parameters Configurations
C H A P T E R Post-Installation Global Parameters Configurations Before an array is shipped, the global parameters are set to default values. This chapter describes how to reconfigure your array by changing these default values. Caution – If you are planning an enterprise configuration using new factory units, be sure to install and set up the units as a partner group before you power on, and change any parameters or create or change any logical volumes.
Page 138: Configuring Cache
Configuring Cache Each Sun StorEdge T3 array controller unit has a 256-Mbytes data cache; each Sun StorEdge T3+ array controller unit has 1 GByte of data cache. Writing to cache improves write performance by staging data in cache, assembling the data into data stripes, and then destaging the data from cache to disk, when appropriate.
Page 139: Data Block Size Configuration
None. No reads or writes are cached. Note – For full redundancy in an enterprise configuration, set the cache mode and the mirror variable to Auto. This ensures that the cache is mirrored between controllers and that write-behind cache mode is in effect. If a failure occurs, the data is synchronized to disk, and then write-through mode takes effect.

Attribute-intensive NFS file system, version 3 64-Kbyte data block size Data-intensive NFS file system, version 3 Decision Support Systems (DSS) Data Warehouse (DW) High Performance Computing (HPC) Note – The data block size must be configured before any logical volumes are created on the units.
Page 141: Configuring Logical Volumes
Configuring Logical Volumes Also called a logical unit number (LUN), a logical volume is one or more disk drives that are grouped together to form a single unit. Each logical volume is represented to the host as a logical unit number. Using the utility on the application host, format you can view the logical volumes presented by the array.
Page 142: Determining The Number Of Logical Volumes
Determining the Number of Logical Volumes You can configure a volume into seven partitions (also known as slices) using the (1M) utility. Alternatively, you can configure virtually a large number of format partitions (also known as subdisks) using VERITAS Volume Manager. Therefore, arrays are best configured as one large volume.
Page 143: Determining A Hot-Spare
The following applications benefit most from the RAID controller hardware of the array: Data-intensive NFS file system, version 3 Note – For more information about RAID levels, see “Using RAID Levels to Configure Redundancy” on page 123. Determining a Hot-Spare A hot-spare is always optional.

Page 145: Using Raid Levels To Configure Redundancy
Using RAID Levels to Configure Redundancy The RAID level determines how the controller reads and writes data and parity on the drives. The Sun StorEdge T3+ array can be configured with RAID level 0, RAID level 1 (1+0), or RAID level 5. The factory-configured LUN is a RAID 5 LUN. Note –...
Page 146: Raid
RAID 0 Data blocks in a RAID 0 volume are striped across all the drives in the volume in order. There is no parity data, so RAID 0 uses the full capacity of the drives. There is, however, no redundancy. If a single drive fails, all data on the volume is lost. shows the data layout in a RAID 0 volume.
Page 147: Raid 5
RAID 5 In a RAID level 5, data is striped across the drives in the volumes in segments, with parity information striped across the drives, as well. Because of this parity, if a single drive fails, data can be recovered from the remaining drives. Two drive failures cause all data to be lost.

Page 157: Post-Installation Partner Groups Configuration
C H A P T E R Post-Installation Partner Groups Configuration This chapter describes how to configure array partner groups. Sun StorEdge T3+ arrays can be interconnected in partner groups to form a redundant and larger storage system. Note – The terms partner group and enterprise configuration refer to the same type of configuration and are used interchangeably in this document.
Page 158: Understanding Partner Groups
Understanding Partner Groups In a partner group, there is a master controller unit and an alternate master controller unit. The master controller unit is the array positioned at the bottom of an array stack in either a rackmounted or tabletop installation. The alternate master controller unit is positioned on top of the master controller unit.
Page 159: How Partner Groups Work
The partner group connection also allows for a single point of control. The bottom unit will assume the role of the master, and from its Ethernet connections, it will be used to monitor and administer the unit installed above it. The master controller unit will set the global variables within this storage system, including cache block size, cache mode, and cache mirroring.
Page 160: Creating Partner Groups
Note – In order for a feature such VERITAS DMP to access a LUN through both controllers in a redundant partner group, the parameter must be set to mp_support to enable this feature. If you are using Sun StorEdge Traffic Manager, the mp_support parameter must be set to mpxio.

Disk Drives Caution – Replace only one disk drive in an array at a time to ensure that no data is lost. Ensure that the disk drive is fully reenabled before replacing another disk drive in the same array. The default configuration for the array is to automatically spin up and reenable a replaced disk drive, then automatically reconstruct the data from the parity or hot- spare disk drives.

Insert the new disk drive gently on the middle of the rails and push it in until it is seated with the centerplane connector.
Page 192: Power And Cooling Units
Power and Cooling Units The power and cooling unit has two active power sources: standby and primary power. Standby power, which is used to power the microcontroller on the interconnect card, is activated when AC power is present. Primary power, which is used to power all remaining circuits and disk drives, is activated when AC or battery power is present and the power switch is on.

Caution – Any power and cooling unit that is removed must be replaced within 30 minutes or the array and all attached arrays will automatically shut down and power off. Latch handle Latch handle Removing the Power and Cooling Unit FIGURE 14-6 6.
Page 195: Ups Battery
UPS Battery The UPS battery is located within the power and cooling unit. The battery provides backup in case of a complete AC power failure and will sustain power to the array long enough to flush cache data to the drives. During a power failure, if the battery is flushing cache data to the drives, battery power becomes depleted.
Page 196: Removing And Replacing The Ups Battery
The battery service life is two years. When the battery approaches the end of its life span, warning messages are sent to the syslog file. The first message is sent 45 days before the end of the life span, followed by a warning message every 5 days thereafter.
Page 197: To Removing And Replacing An Interconnect Card
Note – Even if the LED indicates an interconnect card failure, you should always verify the FRU status using either the CLI or Sun StorEdge Component Manager before replacing the unit. Refer to the Sun StorEdge T3+ Array Administrator’s Manual or Sun StorEdge Component Manager User’s Guide for more information.

Page 199: Controller Card
Controller Card The controller card is redundant only when the array is configured in an enterprise configuration; that is, when the array is connected to another array that contains a controller card. In an enterprise configuration, if there is a controller card failure in a master unit, the controller would failover to the alternate master, which would then assume master controller status.

4. Remove the fiber-optic cable from the FC-AL connector. 5. Unlock the controller card by pushing in on the latch handles ( FIGURE 14-8 6. Pull the controller card out using the latch handles. Caution – The controller card that is removed must be replaced within 30 minutes or the array and all attached arrays will automatically shut down and power off.
