I have a DPT SmartRAID V that I'm using for all of the disks on a RedHat
6 system. Works beautifully, although it did require a module on
install.
> Has anyone tried this on a ICP/Adaptec RAID system?
Well, DPT has been purchased by Adaptec, so, sort of. If you're
thinking of the AAA cards, DON'T BUY ONE. They are just a fancy SCSI
controller, they DO NOT do hardware RAID. They have drivers for NT and
Netware that allow you to boot from the controller, but it's SOFTWARE
RAID. Get a DPT card, Mylex, or AMI card. All have Linux drivers, and
are real hardware RAID controllers.

Jim,
What's your reasoning behind this recommendation? Is it for performance or
ease of use? I'm just curious as I recompiled my kernel with all drivers
compiled into it, nothing left modular and I didn't notice any change in
performance or anything... Not even a seat-o-da-pants feeling of better
performance...
Thanks,

If I abandon my current board, and can find a replacement that has slot
1 PIII's, with DIMM's, along with the 64x66 PCI you mention, I'd be
ecstatic (this causes no harm to electrical devices :). I don't know the
brand SM by this abbreviation though, do you have a URL that mentions
these boards? I have no qualms about abandoning SuperMicro now, but cost
always matters, and recycling current components is a huge plus (rdram,
for example is an extreme cost and disappointment).

Don't mistake bus speed for harddrive speed. Burst is important though,
for not tying up the bus for long periods of time, for raid, or simply
multiple devices hogging things for less time.

The situation is this - we have two servers that are to be replaced. They
have DDS2 tape drives. They will be replaced with newer servers equipped
with DDS3 tape drives. What we want to do is to be able to save data on the
new server's DDS3 drive to a DDS tape, below the 2GB limit of the old DDS2
drives, and then use that tape from the new server to keep the old server
more or less synchronised with regard to possible hardware failure or
integration problems with the "new" server.

There are different raid levels. I've heard roughly equivalent, but
different meanings of the acronym, e.g., Redundant Array of Inexpensive
Disks.
The idea is that each device can store data only so fast, or retrieve it
only so fast. If you split the data across more than one drive, in
theory, you can cut time required to read or write down, since each of n
disks only stores or reads 1/n of the data. There are variations on the
scheme, for example, straight mirroring, which means if one drive dies,
your system simply reports the fact and continues on via the mirror
side. If it is simply a mirror, and both contain the same data, write
time does not improve...but read does. Pure striping splits data,
interwoven, between 2 or more drives, and if any one device dies, it is
lost...but both read and write are faster. Then there are combinations
of mirrored interleaved data, both complete mirror, and mirror of only
CRC checksums. Costs, advantages, disadvantages, vary greatly with the
version. If you run a software only raid, the cpu of the system has to
handle the load of splitting things, or recombining them, thus dual cpu
has a big advantage on software raid. Or you can buy a raid card, and
the cpu sees it only as a hard drive, with the card offloading
things...usually with some sort of hot swap or warm swap added abilities
(and expensive).

have you tried running Xconfigurator as root and see what that detects the

detected and set it up for me with no worries.

Hi there!
And yes you stand corrected. The whole point of my question was that I
remember using this command to "Turbo" my boxen. Many modern
motherboards don't have connection for turbo switch, or it is only for
decorative purposes like changing the numbers on 3 digit LED display, so
I was supprised to have this command available at all.
Have fun...

yepper, like somebody else has said you can use samba to allow your win95
box to access the linux one. You don't have to remove your win95 machine
from the NT domain, just make sure that any services the 95 machine is
currently accessing off the NT server are replicated on your linux
install. (eg nameservers and stuff like that)

If you only have one other machine connected to the linux machine then you
should only need one NIC. (either if you go via a hub or crossover) you
shouldn't have to worry about a second one unless you wnated to join the
two networks together.

First of all, there is a special newsgruup for tape drives which you will
probably find very useful.
linux.dev.tape
to use this drive you have to use the device /dev/ht0 and /dev/nht0
later is NOT self-rewinding.
And programs like kbakup or at least taper
try
tar cf /dev/nht0 <dir-to-backup>
also
man mt

The tape is addressed via the character device associated at boot time.
Look for lines in dmesg output with 'ide-tape'. On my machine 'tar cvzf
/dev/nht0 ./home' and 'tar cvzf /dev/tape ./home' are identical, but
'tar cvzf /dev/hdb ./home' would not work.
Link /dev/tape to the norewind device.
# ls -l /dev/*ht*
crw-rw-rw- 1 root disk 37, 0 May 5 1998 /dev/ht0
crw-rw-rw- 1 root disk 37, 128 May 5 1998 /dev/nht0
# ln -s /dev/nht0 /dev/tape
Get a good mt package. Versions earlier than this have broken
positioning commands. Useful are the seek, tell, status and fsf
commands.

2.2.16 (tried -3, -8 & -12) I have problems accessing ATAPI CD-ROM
Drives from Guest OSs within a Virtual Machine (VMware 2.0.1/2.0.2)!
>From within the Guest OS Data CDs detect as Audio CDs and are unreadable,
then after existing the VM the same Data CD can NO longer be mounted

kernel: attempt to access beyond end of device
kernel: 16:00: rw=0, want=33, limit=0

lies with 2.2.16 or VMware's access of the 2.2.16 ATAPI Driver?
I tried two different CD-ROM Drives in the same PII System, so I do
NOT believe it is a "problem" with the physical drives themselves!
Todate I have NOT received any replies to my posts on the VMware Newsgroups,
hence I do NOT know if I am alone with this "problem"? Bothersome that any
application should be able to adversely the functioning of the ATAPI Driver
and that sequence of operations is determinant!!! Especially curious since
2.2.16 is expected to be used in the upcoming Red Hat 7.0, so hopefully
this can be resolved!!!

I'm considering (strongly) getting a real soundcard and dropping
my onboard garbage for use under Mandrake 7.1. I searched the
supported list at the mandrake site, but still have questions.
The supported list includes:
-SoundBlaster (SB 16/32/64, DS, ESS, Jazz16, Live, or SB clone)
Does "clone" here mean that I can get *any* card that says it's
100% SB compatible? I'm looking at a PCI (with a real audio
processor) that seems like quite a cool card. I know it will
work under my win98, but Linux is where I'll be spending my time
after I get sound and communications going.
Please forgive the stupid question. Thanks for any help.
