can protect against the failure of any hardware component in the I/O path to the disk array by providing an alternate path to all user data. The Disk Array FC60 provides high availability in the following ways: • Supported RAID levels 1, 0/1, 3, and 5 all use data redundancy to protect data when - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 48
of an even number of disks, half of which are primary disks and the other half are mirror disks. If a disk fails or becomes inaccessible, the remaining disk of the mirrored pair provides uninterrupted data access. After a failed disk is replaced, the disk array automatically rebuilds a copy of the - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 49
performance under varying sizes of I/O transactions. Stripe segment size is specified in 512-byte blocks of data. Stripe segment size can affect disk array performance. The smaller the stripe segment size, the more efficient the distribution of data read or written across the stripes in the LUN - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 50
industry-standard RAID levels define the method used for distributing data on the disks in a LUN. LUNs that use different RAID levels can be created on the same disk array. The Disk Array FC60 supports the following RAID levels: • RAID 0 • RAID 1 • RAID 0/1 • RAID 3 (Windows NT and Windows 2000 - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 51
pair. One disk is the data disk and the other is the disk mirror. The disks in a RAID 1 LUN are mirrored by the disk array hardware, which automatically writes data to both the data disk and the disk mirror. Once bound into a RAID 1 mirrored pair, the two disks cannot be accessed as Disk Array High - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 52
the mirrored pair must be located in a different enclosure. When a data disk or disk mirror in a RAID 1 LUN fails, the disk array automatically uses the remaining disk for data access. Until the failed disk is replaced (or a rebuild on a global hot spare is completed), the LUN operates in degraded - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 53
pair must be located in a different enclosure. When a disk fails, the disk array automatically uses the remaining disk of the mirrored pair for data access.

for each channel. A global hot spare can be used to replace any failed data disk within the array regardless of what channel it is on. When a disk fails, the disk array automatically begins rebuilding the failed disk's data on an available global hot spare. When all the data has been rebuilt on - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 62
the global hot spare is part of the LUN, which fulfills the roll of disk 3. 4. When disk 3 is replaced, the disk array begins copying all the information from the former global hot spare to the replacement disk. 5. When copying completes, the LUN is restored to its original configuration. The former - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 63
to rebuild the contents of disk 3 on the hot spare disk. The information on the hot spare is copied to the replaced disk, and the hot spare is again available to protect against another disk failure.

to access the LUN. The first time an I/O is performed to the LUN using the alternate path, the disk array switches ownership of the LUN to the controller on the alternate path. Once the problem with the primary path is corrected, ownership of the LUN should be switched back to the original I/O path - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 65

Functionally, each LUN appears to the host - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 66
If a read I/O requests data that is already in read cache, the disk array services the request from cache RAM, thus avoiding the much slower process of accessing a disk for the data. A pre-fetch capability enables the disk array to anticipate needed data (for example, on a file transfer) and read - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 67
. In this case the write cache image is lost and data integrity on the disk array is compromised. To avoid this problem, never remove both controllers from the disk array simultaneously.

Overview This chapter provides information to assist you in configuring the Disk Array FC60 to meet your specific storage needs. Factors to be considered when configuring the disk array include high availability requirements, performance, storage capacity, and future expandability. This chapter - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 71
. These options include: hardware configuration, RAID level and LUN creation, the number of SC10 disk enclosures used, and system support software. It should be noted that optimizing the disk array for one feature may compromise another. For example, optimizing for maximum performance may increase - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 72

High Availability If your application requires high availability, you should implement the options discussed here.The Disk Array FC60 is fully qualified to run MC/ServiceGuard and MC/LockManager. To work in these environments, a high availability configuration must be - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 73
be selected, however, for the greatest high availability, It is recommended that RAID level 1 be used for optimum high availability. Note The Disk Array FC60 is designed to operate with either one or two controller modules, however for high availability it is highly recommended that two controller - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 74
offers full sequential performance and is more economical to implement. To scale up sequential transfer performance from the host, configure additional disk arrays. This will increase the total I/O bandwidth available to the server. Performance can also be measured by the number of I/O operations - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 75
add more capacity to the Disk Array FC60. There are several ways to increase the storage capacity of the disk array. It can be increased by replacing existing smaller capacity disk modules with larger capacity disk modules, by adding more disk modules to the disk enclosures, or by adding additional - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 76
sequential transfer performance, you will need to add a second disk array and more disk modules. To increase I/Os per second performance, add disk modules. Transaction performance is directly related to the number of disk modules installed in the disk array. 76 Array Design Considerations - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 77
system is shown, but configurations can be adapted to create multi-host, high availability systems.

Two types of addressing are used with the Disk Array FC60: • Peripheral Device Addressing (PDA) - used to address the disk array controller modules. • Volume Set Addressing (VSA) - used to address the disk array LUNs Because each controller module is identified by a unique loop - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 209

8 LUN limit imposed by PDA. The HP SureStore E Disk Array FC60 requires that 32 LUNs (0 - 31) be addressable. To implement VSA, the fibre channel driver creates four virtual SCSI busses, each capable of supporting up to eight LUNs. Each virtual SCSI bus supports the following LUNs: Virtual SCSI Bus - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 211

A quick way to determine the LUN number is to multiply the value of the next-to-last segment times 8, and add the result to the last segment value.

These steps should be performed by the service-trained installer with assistance from the customer where appropriate. Step 1. Determine the Disk Array - HP Surestore Disk Array 12h | HP SureStore E Disk Array FC60 - (English) Advance - Page 217
