*snip*

I've started using the 3Ware IDE RAID controller and been
very impressed with it so far. Using a pair of IBM 75GXP drives
in mirroring mode, disk reads are very fast. The mirroring
works as advertised. I can "fail" a drive by unplugging it
and it keeps running. Rebuilding onto the failed drive 
to return to full mirroring functionality can be done while
the system is running. Sweet.

Only weird thing I note is that if I put my Tekram D390U3W card
in with a Seagate X15 drive it seems I cannot access it. I think
the 3Ware and the Tekram card conflict.

Date: 26 Feb 2001 16:54:09 +0000

A user needs at least 300GB of disk space and that's after formatting,
file system overhead, etc. So I'm reckoning I need at least 6 IBM 60GB
disks and I would prefer to have only one per channel, ie no hard
disks running as slaves. So I could use a little help!

* If I just use three ordinary ATA-100 cards will that cause me any
  problems? (Performance, boot, etc.)

* Will I gain much by using Promise ATA RAID cards? Is there better
  performance, does it reduce the number of IRQs I'm using? Are
  there boot problems if I try to make a RAID device my boot device?

* Anything else I haven't thought if?


Thanks for taking the trouble.

Subject: FastTrak100 - accessing and booting from RAID 0 array
Date: Mon, 26 Feb 2001 17:07:28 GMT

OK, here is how my Promise FastTrak100 is setup:

Channel 1 master/slave has two 45GB drives striped to form an array
with geometry of 11213/255/63.

Channel 2 master has a 28GB drive by itself to form a single-disk span
array with geometry of 3467/255/63.

When installing Red Hat Linux 7.0, I can switch over to the command
prompt and do a 'cat /proc/pci' and get some info on the Promise
controller. Here is a snippet of the info:

0x9400
0x9800
0x9c00
0xa000
0xa400

With this info, I can use the boot parameter 'ide#=#x####,#x####' and
get access to individual drives only. So, when I go to install Red Hat
Linux 7.0, I use:

expert ide2=0x9400,9x9802 ide3=0x9c00,0xa002

Using this, it shows that I have access to 3 drives with geometry
5606/255/63, 5606/255/63, and 3467/255/63. The first two are obviously
members of the striped array and the third is the lone 28GB drive.

I can install to the 28GB drive and Red Hat'll install, boot, and run
just fine. But this is not how I originally wanted to do it, since the
28GB drive is a removable drive, I want Linux on the array. I hesitate
to install to one of the drives in the array because I have this
feeling that it'll corrupt the data that is already there since it is
not reporting the geometry correctly.

Ideally, I want to be able to access and install to the array using
boot parameters. The result of this should be access to a drive of
geometry 11213/255/63.

Does anyone know how to do this? Could the '0xa400' be part of the
solution? That number was not used during the original boot parameter
to access the individual drives.

If you need more info please ask.

Hi,

I have an old 386-20 system, equipped with three modems, which is currently

I can imagine that stringing new wires is a problem, either due to order of the
building owner, and/or the spouse/girlfriend/boyfriend :-).  Or possibly
general klutziness on the part of the installer.  Given that phoneline cards
are somewhat pricey compared to normal ethernet cards, I suspect price of the
cards is not an issue.  Price of an electrician stringing wire would be.  When
I had an electrician string wires to 2 bedrooms and the living room, the cost
was $1,600 (that probably included running cables for the satellite dish to 2
tvs at the same time).

If the only reason you are networking is to share an outside network
connection, it won't matter whether you upgrade to 100bT (unless you maybe have
an OC3 connection to your house, in which case the cost of stringing new wires
is small potatoes).

I forgot to mention that wireless might be the solution instead of using
existing phones.  Going to the 802.11 standard is somewhat more expensive than
the phoneline cards (about $400-600 to connect 2 computers).  I'm currently
using a Orinocco card on my laptop to post this message.  The following link
talks about the various wireless options:

The specifications list 'ETEQ 82C6638AT/6629 AGP' as the chipset,but I 
have read that this is actually a re-branded Via Apollo MVP3 chipset. My 
kernel configuration includes CONFIG_BLK_DEV_VIA82C586=y.

Have you considered that for a requirement of so much disk space access
times to data is also important.

While a RAID5 of 6 60GB EIDE drives would provide the necessary space
would performance be up to the requirement? If so then fine, go ahead and
buy a couple of 4 channel ATA-100 IDE controllers and be happy.

If not then I strongly recommend that you get a real hardware raid card
and a quantity of 10,000 rpm hard drives.

Also bear in mind that you probably want hot swap capability so factor
that in from the outset - it's VERY expensive to have to cobble it on
later.

Your only realistic option is SCSI, preferably using an external

I'm in the market for disk space of this magnitude at the moment as
well.  While the above statement used to be the case, I have heard
a number of *very* informed opinions in support of IDE-SCSI RAID
towers, such as the ones at www.zero-d.com.  It's a tower/rack-mount
full of IDE disks that'll do RAID 0, 1, or 5 (possibly 10, I don't
recall at the moment).  They have hot swappable drives, power supplies
and fans.  Finally, they connect to the host via a SCSI (typically UW or
U2W) connection, so are OS independent.

There was a thread on this on the beowulf mailing list just a bit ago.
You can look at it here:

http://www.beowulf.org/pipermail/beowulf/2001-February/thread.html

These are *far* cheaper than SCSI arrays of similar size.  From initial
quotes I've gotten, I can get 560GB of RAID 5 storage (8*80GB drives)
for ~$6K.  8 73GB SCSI drives alone will run you close to $10K, never
mind the controllers, power supplies, case, etc.

If you don't want an external solution, 3ware sells a PCI card that'll do
RAID 0, 1, and 5 as well.  They have 4 and 8 channel versions, and
fully open source Linux drivers.

Good luck.

If they're going to get heavy use (multiple simultaneous accesses),
then I wouldn't recommend IDE.

What use will this 300Gbyte be put to? Is the data ephemeral or would
there be some need for protection against one of the drives going phut?
