Page 43: Raid Array 3000 Controller
Chapter RAID Array 3000 Controller This chapter describes the major features and characteristics of the Compaq StorageWorks RAID Array 3000 Controller (Controller) in the controller shelf. Controller Overview The controller provides high performance, high-availability access to SCSI disk array subsystems along a Wide-Ultra SCSI bus. With a modular hardware design and an intuitive configuration utility, the controller is designed to meet a wide range of storage needs.
Page 44: Figure 2-1. Raid Array 3000 Single Controller Block Diagram
2-2 RAID Array 3000 Controller Shelf Hardware User’s Guide The controller has two Single Inline Memory Module (SIMM) connectors. The connectors form a mirrored pair when the controllers are configured in a redundant controller configuration; otherwise they are fully accessible by the controller.
Page 45: Controller Features
RAID Array 3000 Controller 2-3 There are two configurations for redundant pairs of controllers: active/active failover mode and active/passive failover mode. In active/active failover, each controller in the redundant pair has one active SCSI host port and one passive SCSI host port. Redundancy groups (virtual LUNS) can be mapped to only one active host port and are not accessible from the passive port or the other controller (that is, partitioned model).
Page 46: Figure 2-3. Storagesets, Partitions, And Disk Drives
2-4 RAID Array 3000 Controller Shelf Hardware User’s Guide From the storage shelf’s perspective, the controller receives the I/O requests from the host and directs them to the devices. Since the controller processes all the I/O requests, it eliminates the host-based processing that is typically associated with reading and writing data to multiple storage devices.
Page 47: Controller Reset And Led Indicators
RAID Array 3000 Controller 2-5 Stripesets (RAID 0) combine disk drives in serial to increase transfer or requests rates. Mirrorsets (RAID 1) combine disk drives in parallel to provide a highly reliable storage unit. RAID 4 provides striping with a fixed parity drive. RAIDsets (RAID 5) combine disk drives in serial—...

2-6 RAID Array 3000 Controller Shelf Hardware User’s Guide Figure 2– 4 shows the Front Panel of the controller. Reset H0 D1 Fault Reset H0 D1 Fault SHR-1049 Figure 2-4. Controller front panel Flexible RAID Set Configuration In addition to its flexible hardware design, the controller’s firmware offers the user the flexibility to configure RAID sets in several different ways: RAID sets can comprise drives from any drive channel and SCSI ID.
Page 49: Custom Components
RAID Array 3000 Controller 2-7 Any drive may be designated as a spare. Spares are global, meaning that in the event of a drive failure, the controller will search for the first available spare on any channel or SCSI ID and automatically begin rebuilding the failed drive’s data.
Page 50 2-8 RAID Array 3000 Controller Shelf Hardware User’s Guide NOTE: The controller will not operate without at least one 16 MB SIMM installed in its cache. Nor will it operate without a UPS power supply connected to the controller. Without a UPS, data stored in the cache, but not yet written to the disk drives, would be lost in the event of a power interruption.
Page 51: Raid Levels Supported
RAID Array 3000 Controller 2-9 RAID Levels Supported The controller supports the following RAID levels: Table 2-2 Raid Levels Supported RAID Level Description Striping without parity Mirroring Striping and mirroring Striping with fixed parity drive Striping with floating parity drive JBOD just a bunch of drives There are some restrictions you must adhere to when creating a RAID set...
Page 52: Raid 0
2-10 RAID Array 3000 Controller Shelf Hardware User’s Guide RAID 0 RAID 0 breaks up data into smaller chunks and writes each chunk to a different drive in the array. The size of each chunk is determined by the controller’s chunk size parameter, which you set in the course of creating a RAID set.
Page 53: Raid 1
RAID Array 3000 Controller 2-11 RAID 1 RAID 1 (also known as mirroring or shadowing) takes data sent by the host and duplicates it on all the drives in an array. The result is a high degree of data availability, since you can lose all but one drive in the array and still have full access to your data.
Page 54: Raid 0+1
2-12 RAID Array 3000 Controller Shelf Hardware User’s Guide RAID 0+1 RAID 0+1 (see Figure 2– 7) combines RAID 0 (striping) with RAID 1 (mirroring). In RAID 0+1 write, the controller breaks up the data block from the host into smaller chunks, then writes the chunks to half the drives in the array, while writing duplicate chunks to the remaining drives.
Page 55: Table 2-4 Raid 0+1 Example
RAID Array 3000 Controller 2-13 When the controller creates a RAID 0+1 set, it first sorts the drives by channel number and SCSI ID. Then it stripes the data across every other drive and forms a mirrored pair with the first two drives, another mirrored pair with the second two drives, and so on.
Page 56: Raid 4
2-14 RAID Array 3000 Controller Shelf Hardware User’s Guide RAID 4 RAID 4 breaks up host data into chunks, calculates parity by performing an exclusive-or on the chunks, and then writes the chunks to all but one drive in the array and the parity data to the last drive (Figure 2– 8). When the host...
Page 57 RAID Array 3000 Controller 2-15 In the event of a single drive failure, a RAID 4 array will continue to operate in degraded mode. If the failed drive is a data drive, writes will continue as normal, except no data will be written to the failed drive. Reads will reconstruct the data on the failed drive by performing an exclusive-or operation on the remaining data in the stripe and the parity for that stripe.
Page 58: Raid 5
2-16 RAID Array 3000 Controller Shelf Hardware User’s Guide RAID 5 RAID 5 addresses the bottleneck issue for barrages of widely scattered, small I/O operations (Figure 2– 9). Like RAID 4, RAID 5 breaks up data into chunks, calculates parity, and then writes the chunks in stripes to the disk drives, saving one drive one each stripe for the parity data.
Page 59: Jbod
RAID Array 3000 Controller 2-17 While RAID 5 is ideally suited for applications with many, small I/O operations, there is no reason why it cannot function equally well for applications with large, sequential I/O operations. This makes RAID 5 an excellent all-purpose RAID level.
Page 60: Initialization
2-18 RAID Array 3000 Controller Shelf Hardware User’s Guide Initialization During initialization, the firmware in the RAID 3000 verifies that both controllers have consistent configurations including identical memory cache and system parameters. If the controller setups are incompatible, the set is not bound and each controller operates in stand-alone mode.
Page 61: Environmental
RAID Array 3000 Controller 2-19 Environmental The controller incorporates a set of on board sensors to detect abnormal operating conditions that may affect data safety. Backup Power Management The controller must be connected to the UPS to prevent the subsystem cache from being corrupted during unexpected losses of power.
Page 63: Installation And Maintenance
Chapter Installation and Maintenance This chapter describes how to install the controller shelf in a RETMA or metric-style storage cabinet and then make the cable connections to the Uninterruptable Power Supply (UPS), Device expansion shelves and host system. The maintenance section describes how to interpret the status of the LEDs on the front panel of the controller shelf.
