http://storusint.com/pdf/SCSI_vs_FC.pdf seems very helpful!

I have not surveyed the FC offerings for small servers, PCs, Laptops. While it might be SAN oriented, I see they are available in popular form factors:

FC hard drive price compare - Google Search

Seems a bit faster than the hottest SCSI, and maybe with simpler/cheaper controller, cabling, termination. Controller comes as a plug in or motherboard.

Since it fits into the SCSI configuration metaphor, it is not surprising that it inherits many configuration attributes from SCSI.

I wonder if FC has more latency and lower random performance than SCSI, with the serial access and optical encoding/decoding, not to mention higher contention if many/more devices are on a channel.

Re-using disks

I would like to know if I can move the disks from a V240 chassis into a V440 chassis to use the increased resources (CPU & Memory) to boost performance. I know you can move disks between V210/240 chassis's, but I'm not sure if this would work between 240s & 440s. Any help would be much appreciated. (4 Replies)

tapeinfo

TAPEINFO(1)						      General Commands Manual						       TAPEINFO(1)

NAME

       tapeinfo - report SCSI tape device info

SYNOPSIS

       tapeinfo -f <scsi-generic-device>

DESCRIPTION

       The  tapeinfo  command  reads  various information from SCSI tape drives that is not generally available via most vendors' tape drivers. It
       issues raw commands directly to the tape drive, using either the  operating  system's  SCSI  generic  device  (	e.g.  /dev/sg0	on  Linux,
       /dev/pass0 on FreeBSD) or the raw SCSI I/O ioctl on a tape device on some operating systems.

       One  good  time	to  use 'tapeinfo' is immediately after a tape i/o operation has failed. On tape drives that support HP's 'tapealert' API,
       'tapeinfo' will report a more exact description of what went wrong.

       Do be aware that 'tapeinfo' is not a substitute for your operating system's own 'mt' or similar tape driver control program. It is intended
       to supplement, not replace, programs like 'mt' that access your operating system's tape driver in order to report or set information.

OPTIONS

       The first argument, given following -f , is the SCSI generic device corresponding to your tape drive.  Consult your operating system's doc-
       umentation for more information (for example, under Linux these are generally start at /dev/sg0 under FreeBSD these start at /dev/pass0).

       Under FreeBSD, 'camcontrol devlist' will tell you what SCSI devices you have, along with which 'pass' device controls  them.  Under  Linux,
       "cat /proc/scsi/scsi" will tell you what SCSI devices you have.

BUGS AND LIMITATIONS

       This program has only been tested on Linux with a limited number of tape drives (HP DDS4, Seagate AIT).

AVAILABILITY

       tapeinfo  is  currently being maintained by Eric Lee Green <eric@badtux.org> formerly of Enhanced Software Technologies Inc. The 'mtx' home
       page is http://mtx.sourceforge.net and the actual code is currently available there and via CVS from http://sourceforge.net/projects/mtx/ .
