Fibre Channel Hard Disk Drive
The Enterprise Virtual Array supports any combination of five different Fibre Channel Hard Disk
Drives (HDD) with multiple capacity points and two different rotational speeds. Three drive
capacity points are supported at 36 GB, 72 GB, and 146 GB. Two rotational speeds are supported
at 10,000 RPM and 15,000 RPM.
The following individual drive capacity/rotational speed combinations are available:
146GB 10,000 RPM Fibre Channel HDD
72GB 15,000 RPM Fibre Channel HDD
72GB 10,000 RPM Fibre Channel HDD
36GB 15,000 RPM Fibre Channel HDD
36GB 10,000 RPM Fibre Channel HDD
Five different Fibre Channel HDDs for the Enterprise Virtual Array provides tremendous
flexibility to the target customer base by allowing mixing and matching of capacity and
performance to application needs. Application areas seen as potential markets include OLTP, ERP,
and any other applications requiring large amounts of online storage.

Ⅴ.Hard disk data organization
1.Primary formatting of hard disk
Before restoring data, hard disk usually needs low-level format, partition, high-level format to be
used. The function is establishing certain data logical structure on physical hard disk. Usually hard
disk is divided into 5 regions: MBR, DBR, DIR, FAT and DATA (Here we do not introduce FAT
and NTFS file system), which altogether store and manage data.
