CHAPTER 1 Array Configuration Overview This chapter describes the Sun StorEdge T3 and T3+ arrays, the connection ports, and Fibre Channel connections. It also describes basic rules and recommendations for configuring the array, and it lists supported hardware and software platforms. Note – For installation and cabling information, refer to the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.
The array can be used either as a standalone storage unit or as a building block, interconnected with other arrays of the same type and configured in various ways to provide a storage solution optimized to the host application. The array can be placed on a table top or rackmounted in a server cabinet or expansion cabinet. The array is sometimes called a controller unit, which refers to the internal RAID controller on the controller card. Arrays without the controller card are called expansion units.
Serial port (RJ-11) 10BASE-T Ethernet port (RJ-45) FC-AL data connection port Note: FC-AL port requires an MIA for cable connection. FIGURE 1-1 Sun StorEdge T3 Array Controller Card and Ports The Sun StorEdge T3+ array controller card contains: ■ One Fibre Channel-Arbitrated Loop (FC-AL) port using 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.
Serial port (RJ-45) 10/100BASE-T Ethernet port (RJ-45) FC-AL data connection port (LC-SFF) FIGURE 1-2 Sun StorEdge T3+ Array Controller Card and Ports Interconnect Cards The interconnect cards are alike on both array models. There are two interconnect ports on each card: 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.
Interconnect cards Output Input FIGURE 1-3 Interconnect Card and Ports Chapter 1 Array Configuration Overview 5
Array Configurations Each array uses Fibre Channel-Arbitrated Loop (FC-AL) connections to connect to the application host. An FC-AL connection is a 100-Mbyte/second serial channel that enables multiple devices, such as disk drives and controllers, to be connected. Two array configurations are supported: ■ Workgroup. This standalone array is a high-performance, high-RAS configuration with a single hardware RAID cached controller.
Alternate master controller unit Interconnect cables Application host Ethernet connection Host-bus adapters Master controller unit FC-AL connection Management host Ethernet connection Ethernet port LAN FIGURE 1-5 Enterprise Configuration Note – Sun StorEdge T3 array workgroup and enterprise configurations require a media-interface adapter (MIA) connected to the Fibre Channel port to connect the fiber-optic cable. Sun StorEdge T3+ array configurations support direct FC-AL connections.
Configuration Guidelines and Restrictions Workgroup Configurations: ■ 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. ■ Sun StorEdge T3 array workgroup configurations are supported in Sun Cluster 2.2 environments.
Configuration Recommendations ■ Use enterprise configurations for controller redundancy. ■ Use host-based software such as VERITAS Volume Manager (VxVM), Sun Enterprise™ Server Alternate Pathing (AP) software, 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.
Supported Software The following software is supported on Sun StorEdge T3 and T3+ arrays: ■ Solaris 2.6, Solaris 7, and Solaris 8 operating environments ■ VERITAS Volume Manager 3.04 and later with DMP ■ Sun Enterprise Server Alternate Pathing (AP) 2.3.1 ■ Sun StorEdge Component Manager 2.1 and later ■ StorTools™ 3.3 Diagnostics ■ Sun Cluster 2.2 and 3.0 software (see “Sun Cluster Support” on page 10) ■ Sun StorEdge Data Management Center 3.0 ■ Sun StorEdge Instant Image 2.
■ Switches are not supported. ■ Hubs must be used. ■ The Sun StorEdge SBus FC-100 (SOC+) HBA and the onboard SOC+ interface in Sun Fire™ systems are supported. ■ On Sun Enterprise 6x00/5x00/4x00/3x00 systems, a maximum of 64 arrays are supported per cluster. ■ On Sun Enterprise 10000 systems, a maximum of 256 arrays are supported per cluster. ■ To ensure full redundancy, host-based mirroring software such as Solstice DiskSuite (SDS) 4.2 or SDS 4.2.1 must be used. ■ Solaris 2.

CHAPTER 2 Configuring Global Parameters When 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/change any logical volumes.
Configuring Cache for Performance and Redundancy Cache mode can be set to the following values: ■ Auto. The cache mode is determined as either write-behind or write-through, based on the I/O profile. If the array has full redundancy available, then caching operates in write-behind mode. If any array component is non-redundant, the caching mode is set to write-through. Read caching is always performed. Auto caching mode provides the best performance while retaining full redundancy protection.
Configuring Data Block Size The data block size is the amount of data written to each drive when striping data across drives. (The block size is also known as the stripe unit size.) The block size can be changed only when there are no volumes defined. The block size can be configured as 16 Kbytes, 32 Kbytes, or 64 Kbytes. The default block size is 64 Kbytes. A cache segment is the amount of data being read into cache. A cache segment is 1/8 of a data block.
Note – The data block size must be configured before any logical volumes are created on the units. Remember, this block size is used for every logical volume created on the unit. Therefore it is important to have similar application data configured per unit. Data block size is universal throughout a partner group. Therefore, you cannot change it after you have created a volume. To change the data block size, you must first delete the volume(s), change the data block size, and then create new volume(s).
Note – Individual physical disk drives are not visible from the application host. Refer to the Sun StorEdge T3 and T3+ Array Administrator’s Guide for more information on creating logical volumes. Guidelines for Configuring Logical Volumes Use the following guidelines when configuring logical volumes: ■ The array’s native volume management can support a maximum of two volumes per array unit.
■ Data-intensive NFS, version 3 ■ DSS ■ DW ■ HPC Note – If you are creating new volumes or changing the volume configuration, you must first manually rewrite the label of the previous volume using the autoconfigure option of the format(1M) UNIX host command. For more information on this procedure, refer to the Sun StorEdge T3 and T3+ Array Administrator’s Guide. Caution – Removing and reconfiguring the volume will destroy all data previously stored there.
Note – Only one hot spare is allowed per array and it is only usable for the array in which it is configured. The hot spare must be configured as drive 9. Drive 9 will be the hot spare in the unit. So, for example, should a drive failure occur on drive 7, drive 9 is synchronized automatically with the entire LUN to reflect the data on drive 7. Once the failed drive (7) is replaced, the controller unit will automatically copy the data from drive 9 to the new drive, and drive 9 will become a hot spare again.
If the volume has a hot spare configured and that drive is available, the data on the disabled drive is reconstructed on the hot-spare drive. When this operation is complete, the volume is operating with full redundancy protection, so another drive in the volume may fail without loss of data. After a drive has been replaced, the original data is automatically reconstructed on the new drive. If no hot spare was used, the data is regenerated using the RAID redundancy data in the volume.
■ Second, you can use third-party software on the host system to create as many partitions as desired from a given volume. In the Solaris environment, you can use VERITAS Volume Manager or Solaris Logical Volume Management (SLVM) formerly known as Solstice DiskSuite (SDS) for this purpose. Note – For information on using the format utility, refer to the format (1M) man page. For more information on third-party software or VERITAS Volume Manager, refer to the documentation for that product.
Configuring RAID Levels The Sun StorEdge T3 and T3+ arrays are preconfigured at the factory with a single LUN, RAID level 5 redundancy and no hot spare. Once a volume has been configured, you cannot reconfigure it to change its size, RAID level, or hot spare configuration. You must first delete the volume and create a new one with the configuration values you want.
CHAPTER 3 Configuring Partner Groups Sun StorEdge T3 and 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. Note – Partner groups are not supported in Sun Cluster 2.2 configurations.
Ethernet connection Alternate master controller unit Application host Interconnect cables Host-bus adapters Master controller unit FC-AL connection Management host Ethernet connection LAN FIGURE 3-1 Ethernet port Sun StorEdge T3 Array Partner Group Note – Sun StorEdge T3 arrays require a media-interface adapter (MIA) connected to the Fibre Channel port on the controller card to connect the fiber-optic cable. Sun StorEdge T3+ array configurations support direct FC-AL connections.
Any controller unit will boot from the master controller unit’s drives. All configuration data, including syslog information, is located on the master controller unit’s drives. How Partner Groups Work If the master controller unit fails and the “heartbeat” between it and the alternate master stops, this failure causes a controller failover, where the alternate master assumes the role of the master controller unit.
Creating Partner Groups Partner groups can be created in two ways: ■ From new units ■ From existing standalone units Instructions for installing new array units and connecting them to create partner groups can be found in the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual. To configure existing standalone arrays with data into a partner group, you must go through a qualified service provider. Contact your SunService representative for more information.
CHAPTER 4 Configuration Examples This chapter includes sample reference configurations for Sun StorEdge T3 and T3+ arrays. Although there are many supported configurations, these reference configurations provide the best solution for many installations.
Single Host With One Controller Unit FIGURE 4-1 shows one application host connected through an FC-AL cable to one array controller unit. The Ethernet cable connects the controller to a management host via a LAN on a public or separate network, and requires an IP address. Note – This configuration is not recommended for RAS functionality because the controller is a single point of failure. In this type of configuration, use a host-based mirroring solution to protect data in cache.
Single Host With Two Controller Units Configured as a Partner Group FIGURE 4-2 shows one application host connected through FC-AL cables to one array partner group, which consists of two Sun StorEdge T3+ arrays. The Ethernet connection from the master controller unit is on a public or separate network and requires an IP address for the partner group. In the event of a failover, the alternate master controller unit will use the master controller unit’s IP address and MAC address.
Host Multipathing Management Software While Sun StorEdge T3 and T3+ arrays are redundant devices that automatically reconfigure whenever a failure occurs on any internal component, a host-based solution is needed for a redundant data path.
Single Host With Four Controller Units Configured as Two Partner Groups FIGURE 4-4 shows one application host connected through FC-AL cables to four arrays configured as two separate partner groups. This configuration can be used for capacity and I/O throughput requirements. Host-based Alternate Pathing software is required for this configuration. Note – This configuration is a recommended enterprise configuration for RAS functionality because the controller is not a single point of failure.
Single Host With Eight Controller Units Configured as Four Partner Groups FIGURE 4-5 shows one application host connected through FC-AL cables to eight Sun StorEdge T3+ arrays, forming four partner groups. This configuration is the maximum allowed in a 72-inch cabinet. This configuration can be used for footprint and I/O throughput. Note – This configuration is a recommended enterprise configuration for RAS functionality because the controller is not a single point of failure.
