The HDPac™ is available in three sizes. The HDPac™2 supports two drives for redundant mirroring (Raid 1) or performance striping (Raid 0). The HDPac™4 supports four drives for either Raid 5 redundancy or Raid 0, streaming stripe performance. Finally the HDPac™ 8 provides a single eight drive removable magazine which can be configured as JBOD, Raid 0, 1, 5 or 6.
Any HDPac size can be installed into any system of equal or greater drive slots. For example, a 4 drive backplane used in the MaxPac X Class workstation could support either two HDPac2 magazines or a single HDPac4. An eight drive backplane could support any combination HDPac's whose drive count was equal to or less than eight. For example four HDPac2 magazines could be used or two HDPac2 units and a single HDPac4 or two HDPac4 units or a single HDPac8.
All drives in a given magazine must be the same size to ensure proper RAID performance. Drives may be selected from 500GB, 1TB, 2GB or 3TB 7200rpm SATA drives. This provides up to 24TB of raw storage in an HDPac™ 8.
Because of the value of the SATA hard drive technology and relatively low price of the HDPac™ system, HDPac™ s using Raid 5 redundancy are an excellent choice for data backup and even archive applications. Because all RAID setup data is storage on the drives within the HDPac™, they can be moved between systems without complications. There is no setup or format issues so long as supplied Raid controllers are used in the host computer.
HDPac™ s can be used on any system with an open PCI-X or PCIe x4 or larger slot. It does not have to be a portable system to be of value.
HDPac™ 4 and HDPac™ 8 magazines can be transported using custom water tight transport cases which are designed to allow the units to survive being dropped in the water or dropped onto concrete from heights of over 3 feet.
