Introduction
Overview of functions
Maximum capacity of the unit
The maximum capacity of one set in the basic system is 547.2 TB (for 152 magazines [3.6 TB], unformatted).
The maximum capacity of the maximum system configuration, which consists of five Extension Modules as well as
the basic system above, is 1915.2 TB (for 532 magazines [3.6 TB], unformatted).
Read/Write speed
The maximum read/write speed per drive system is 432 MB/sec (RAID 0/3.6 TB magazine).
Interface
A Serial Attached SCSI (“SAS”) system and a control interface designed to control devices such as the changer unit
are mounted as drive interfaces.
In addition, DATA ARCHIVER Control Software (DA control software), which is to be installed on the server to be
connected to the unit, has an SCSI host interface designed to be connected to an application.
Compatibility with 19-inch rack
The unit can be installed in a 19-inch rack with a depth of 1,000 mm (39.4
z
) that conforms to the EIA standard.
Obtain a rack that meets the following requirements:
≥
A standard 19 inch rack that conforms to EIA standards
≥
A server rack (must have front and rear panel mount frames and square mounting holes)
≥
A rack that has mounting holes with universal spacing
≥
A rack with a mounting hole size of at least
9.3 mm (0.4
q
)
≥
A rack with a height of at least 16U (Base Module (LB-DH70A): 6U, Bottom Module (LB-DF81): 4U, Extension
Module (with the Writer Unit) (LB-DF72A): 6U)
≥
A rack that can withstand a load exceeding the combined weight of the modules to be mounted (
* A rack with a depth of at least 1,000 mm (39.4
q
) is recommended.
≥
Install the panel mount frames so that the ones on the front and rear sides are 660 mm (26.0
q
) to 790 mm (31.1
q
)
apart.
≥
Install the drawer-side’s panel mount frames so that the distance between an imaginary line formed by these
frames and an imaginary line extending horizontally from the projection on the inner surface of the rack’s drawer-
side door will be 55 mm (2.2
q
) to 115 mm (4.5
q
). (The frames can be adjusted in 3 steps at 20 mm (0.8
q
) intervals)
