Note3: Although the subsystem with a configuration of RAID6, RAID 5, RAID 1, or RAID 1+0 providesdata reliability enhanced by means of redundancy, a possibility remains that user data is lost owing toan unexpected failure of a host computer or hardware/software of the subsystem itself. Therefore,

users are requested to back up all data for restoration in case where the original data is lost.RAID 0+1 is described in place of RAID 1+0 in some places, however, it has the same meaning as RAID1+0.

Note 1:When 12 or more units are mounted on the rack frame, an extra-cost optional PDB is required.

Note2:

The backup time of the data on the Cache memory is based on two fully charged batteries.

The volatility of the data in the cache memory is ensured against power trouble such as a suddenpower failure. It transfers data in the Cache memory to Disk drives by turning off the power

normally, and prevents the battery charge from being wasted. When the array enters the Cache Backup mode, the orange Warning LED on the battery may

illuminate. It indicates that the battery voltage has dropped below a specified level, and that theremaining capacity of the battery is not sufficient to keep the cache alive after a power failure.When this happens, the array automatically disables the write cache function. When the battery ischarged, the warning indication disappears, and the array resumes the operation enabling theWrite Cache function.The warning indication disappears within six hours at the latest. Even when the warning is beingindicated, normal functional operation is assured although the operation is performed in the Write-Through mode and the Read/Write performance is lowered because the Write Cache function isdisabled.The battery can be damaged by long term storage or operating at a high aMBient temperature.Avoid using a battery in unnecessarily continuous operation at high temperature.

If the array is not energized for more than 12 months, over-discharging of the battery occurs and

it may cause unrecoverable damage to the battery. To prevent this charge the battery for at leastsix hours at least once every six months.

22 Power Cables


Power Cable and Plug IdentificationYou must use power cables which meet the safety requirements of countrieswhere the AMS 2100/2300 is used. Common power cables are shown in thefollowing table.

1. ANSI: American National Standards Institute

2. NEMA: National Electrical Manufactures Association

3. IEC: International Electrotechnical Commission

4. CEE: International Commission on Rules for the Approval of Electrical

5. Equipment

6. BS: British Standard Institution

7. AS: Standards Association of Australia

CAUTION! When purchasing the AC power cable, make sure that the cablehas proper rating and meets the countrys safety requirement. Otherwise,an electric shock or machine failure may be caused.

Fibre Channel Connection Specifications

System Configuration

When constructing a system with the Direct Connection or FC-SWConnection, consider the following:

If you connect an AMS 2100/2300 directly to a host, set Loop value tothe Fibre Channel topology setting on theAMS 2100/2300.

If you connect an AMS 2100/2300 with a FC-SW, you should set thePoint to Point value to fibre channel topology setting on the AMS2100/2300.

Since high-speed serial data transfer is performed via Fibre Channel,high-quality Fibre Channel cables that conform to the FC-PH standard.

Number of Logical Blocks by RAID Level

The following table lists the number of logical blocks used with the RAIDlevels used in the AMS 2100/2300.

NOTE:

The values of storage capacity are calculated as 1 GB = 1,000,000,000bytes. This definition is different from the definition of 1 GB normally used

with personal computers (1 KB = 1,024 bytes).A logical unit can divide a RAID group into as many as 2048 logical blocks.Set the number of logical blocks for each logical unit using the followingmultiples in accordance with RAID levels.

ConfigurationsThis chapter lists the storage capacities corresponding to RAIDlevels and configurations for the Hitachi AMS 2000 Family StorageSystem. It covers the following key topics:

RAID 0 Capacities (146 GB)


RAID 5 Capacities (146 GB) RAID 6 Capacities (146 GB)

RAID 1+ 0 Capacities (146 GB)









RAID 6 Capacities (400 GB) RAID 1+ 0 Capacities (400 GB)

NOTE:

The upper and lower values in each cell show the number of mountedDisk drives and disk capacity respectively. Spare disk drives are notincluded.

The values of storage capacity are calculated as 1 GB = 1,000,000,000bytes. This definition is different from the definition of 1 GB =1,024,000,000 bytes that is normally used
