The TeraPac® supports 8 removable SATA 3.5” hard drives providing up to 48TB of raw storage and 42TB of Raid 5 protection. These 8 removable drives are connected to the host computer via two eSASx4 supplied cables. These cables connect to a special Raid controller which has been enhanced with external I/O kits. Raid 0 stripping for performance without redundancy or Raid 1 mirror or Raid 5 for failed drive without loss of data protection. Advanced users can also take advantage of Raid 6 for multiple failed drive support.
The workstations use the HDPac family of removable drive magazines. The HDPac4 four drive magazine is used with the MaxPac XL, SL and ML as well as the MaxCube and MaxRax product offerings. The TeraPac® can support two HDPac4 magazines or a single HDPac8 eight drive magazine. If four mirrored pairs of drives are used, the HDPac2 is available. These can be arranged in combination of HDPacs that sum to 8 drives. HDPacs can be shuffled in the TeraPac® in any order without loss of data integrity and without concern for mating a particular drive in a particular TeraPac® hard drive slot. Furthermore, drives can be shuffled within the HDPac magazine without concern for order or loss of configuration.
The HDPac removable Raid magazines can be interchanged between systems using the LSI MegaRAID.
A unique feature of the HDPac is the ability to hot swap individual failed hard drives without having to shut down the system or take them off line. This can be done without removing the HDPac magazine. The individual drives can be removed from the magazine without removing it from the TeraPac® or the MaxPac.
Each TeraPac® has its own self-contained global power supply, cooling and air filtration system. Also included is a customized Pelican 1430 water tight roller case for transporting the TeraPac®3 system and cables.
Each HDPac4 and HDPac8 hard drive magazine is available with a custom Pelican case which is convenient for transporting secure data separate from the computer or TeraPac®3. The HDPac4 uses a custom Pelican 1300 and the HDPac8 uses a custom Pelican 1400.
SATA or SAS hard drives are available in sizes of 2TB, 4TB and 6TB. All drives in the same HDPac must be identical size and type.
