Concepts and Management Disk Array Features Stage 1: Low Data Storage A newly installed disk array will typically have only a small amount of data stored on it. In this case, the disk array has room to keep all data in RAID 0/1. All I/Os can be serviced from RAID 0/1, so disk array performance is - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 86
the percentage of data stored in RAID 5 becomes. The disk array examines all data and moves it to RAID 5 only if it has not been updated recently. Write I/Os are serviced faster from RAID 0/1, so this technique helps maintain disk array performance by keeping data that has the highest probability of - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 87
most writes from RAID 0/1, performance is maintained. But if the number of writes exceeds the current available RAID 0/1 space, the disk array must begin servicing writes from RAID 5 and performance begins to suffer. When data residing in RAID 5 must be updated, it is usually necessary to move - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 88
is divided into entities called logical drives or LUNs. The host operating system treats each disk array logical drive as an individual disk, subdividing it again if necessary into partitions. The disk array can be divided into up to eight logical drives. To maintain data redundancy and improve - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 89
tested and certified for operation in the disk array. Only supported disks are guaranteed to work properly in the disk array. You can include an unsupported disk manually, but there is no assurance that it will operate properly in the disk array. • Failed - the disk is not functional and cannot be - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 90
to a second disk failure until the rebuild is complete. To perform a rebuild (automatic or manual), the disk array must have adequate disk array to complete the rebuild as quickly as possible, but system performance may suffer because host I/Os are delayed. Low rebuild priority instructs the array - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 91
controller. This capability is called Auto Failover. NOTE! To have uninterrupted access to data during Auto Failover, your host disk array driver must support failover capability (multiple paths to the same device). The contents of the controller NVRAM is updated on both controllers simultaneously - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 92
means other than turning off the switch, the array will not have time to perform a successful Shutdown. In this case, the battery can sustain the NVRAM contents for a minimum of one week. Shutdown can be initiated manually using the disk array control panel or using a host software utility.

The data resiliency feature for HP AutoRAID provides a means of recovering data after loss of NVRAM when the disk array is not under some workloads. This feature is supported on controller firmware versions later than HP40. 94 Concepts - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 95
of your data in NVRAM. Each controller module contains dual backup batteries, which provide power to the controller NVRAM when ac power to the disk array enclosure is off. Many factors affect battery life, including not only time of battery use, but also time of battery storage. Controller batteries - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 96
to use its full capacity. In this situation, the array can only use capacity equal to that of the largest disk already installed in the array. For example, if your disk array has only 4.3-Gigabyte disks and you add a single 9.1-Gigabyte disk, the array can only use 4.3 Gigabytes of the high-capacity - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 97
Disk Array Hardware Figure 23. Installing a Second High-Capacity Disk Disk Stamps Because data is distributed across all disks, the array controller must keep track of which disks are installed in the array.

The fan modules provide the air flow necessary to maintain - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 99
SCSI addresses and all other operating parameters are set internally by the disk array controller. There are no hardware jumpers on the disk modules. To ensure optimum performance, the disk modules should be distributed equally across the internal SCSI busses. This is accomplished by simply making - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 100
for each logical drive is distributed across all the disks in the array. • Data Redundancy - capacity required to support the RAID 0/1 and RAID 5 storage techniques used by the disk array for data redundancy. This capacity is managed by the array controller and cannot be altered or reduced. This is - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 101
in this example is 2 Gigabytes. • Gigabytes for parity - This is the capacity used to support the data protection provided by RAID 5. When using disks of different sizes, the disk array divides the capacity into segments.

module into an HP SureStore E Disk Array 12H, the controller firmware of the disk array must be at revision HP54 or higher.

This maintains unallocated and enabling performance - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 104
good idea to backup all your data before upgrading the capacity of the disk array. • The disk modules must be replaced one at a time, and the disk array must be allowed to rebuild the data from the disk module before a another disk module is removed. This ensures that no data is lost as a result of - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 105
performance. • Amount of available RAID 0/1 - In most cases, the more RAID 0/1 space available, the better the disk array performance. With enough RAID 0/1 space, the disk array can service all write I/Os from RAID 0/1, thus allowing an optimum write working set.

the ability to recover ("undelete," or "salvage") files that have been deleted. They can do this because the data remains on the disk media.

RAID stands for "Redundant Array of Independent Disks." The disk array implements this technology to connect several disk drives to one Disk Array Controller. Several different forms of RAID implementations have been defined. The RAID implementations supported by the disk array include RAID 0/1 and - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 268
in order to add more capacity or adjust the RAID mode. The disk array does not require a Reload to make use of additional disk space because of the automatic Balancing and Dynamic Data Migration inherent in HP AutoRAID™ Array Technology. Relocated Blocks are data blocks that are relocated from RAID - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 269

The maximum capacity is therefore 96 Megabytes. The SIMMs provide Error Correction Code (ECC). Status - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 270
loses its source of power. VEB VEB (Very Early Busy) is a SCSI parameter. VEB instructs the disk array to return a BUSY response during its power-on sequence. Following a power-on, it can take the disk array up to three minutes to complete its internal self-test sequence. During this time, the - HP Surestore Disk Array 12h | HP SureStore E Disk Array 12H User's and Service M - Page 271
