iXOS-JUKEMAN fully uses the Mercury's parallel capabilities and effectively
serves 14 requests per minute for different CDs with a single Mercury. The four
drives make it a good choice for archives in which high throughput and fast
response times for many client requests are key requirements.
The Mercury is simple to use. Its CD tray enables the server to import and
export CDs without mistakes, and three removeable magazines for 50 CDs each
allow to quickly exchange 50 CDs, 100 CDs, or all 150 CDs.
The Mercury changer is controlled by a serial line with a capacity for up to 16
jukeboxes (even for mixed use with CDR100 jukeboxes on the same line). Note
that the front key must be locked to permit software control.
The order of drives in the device description file must be the same as the
order of the drive numbers (not the order of the SCSI IDs). On the back of
newer Mercury 31/40 (20) jukeboxes there are four (two) switches to set the
SCSI IDs. Older Mercury 31/40 models use IDs 3 to 6 corresponding to drives 1
to 4; Mercury 20 models use IDs 3 and 4 for the two drives. The first drive in
the device description file must be drive 1 of the jukebox, and so on.
Note that as of iXOS-JUKEMAN version 2.1 you can combine the two lines for the
serial line and the robot ID by using the syntax robot=<serial
port>,<robid>.
The tray simplifies import and export of CDs. To import a CD, call:
cdadm insert <device>
and the jukebox opens the tray. Insert a CD and press any button or the tray, and the jukebox closes the tray. The server inspects the new CD and it appears in the server's file system views. If you want to remove a CD, call:
cdadm remove <device>
and the server moves a CD to the tray and opens it. The server preferably removes an invalid CD. If you want to choose a particular CD, you can specify its slot number or name in the default name format. For example,
cdadm remove device 25
causes the jukebox to remove the CD from slot 25, and
cdadm remove device x11r5
causes the jukebox to remove the CD named x11r5.
The Mercury can be fitted with recorders supported by iXOS-JUKEMAN.
Please note that the Mercury jukebox must be locked with the key switch to
operate with iXOS-JUKEMAN.
For
NSM Mercury and Satellite jukeboxes with Plextor drives, iXOS-JUKEMAN supports
accelerated insertion of CDs. To use this feature, enter an additional line
"ftoc=<file name>" in the device description file. The
server will use this file to store information normally read in the first few
seconds after a CD is inserted into a drive. If the same CD is inserted into
the same drive at a later time, the server will send this information to the
drive, so the drive will not need to read it from the CD. The drive will be
ready to read data a few seconds earlier, and the clients accordingly will get
the data a few seconds earlier.
