Failure of brand new drive... possibly due to staggered spinup? by
Dan Lenski
Hi all,
I've just experienced a mystifying failure of a hard disk that was
literally only one day old. It is a Hitachi Travelstar 5K160 (80gb
5400RPM SATA) that came with my new Dell laptop. I had installed
Ubuntu Feisty Linux, and everything seemed to be working fine, and I
even checked the...

Storage across multiple servers? by
JB Orca
I am trying to find out how to do something that does not make much
sense to me. I have spoken to a few people who say they have taken
multiple servers (1u in this case) and striped the drives on those 1u
servers so that all servers in the group were seeing all data on all
servers.
Does this make...

SCSI vs SATA Hih-Perf by

Hello all,
Which of the two following architectures would you choose for a
high-perf NFS server in a cluster env. Most of our data ( 80% ) is
small ( 64 kb ) files. Reads and Writes are similar and mostly random

UFS 'limits'? by

anyone know how extensively Sun or anyone else has tested
the scalability of UFS in real-world write-intensive
environments in terms of number of files and/or dirs?
i'm not talking theoretical limits, but what's actively in
use every day? We've had some issues with NTFS at

SD Card - boot sector by
Peter Sommerfeld
Hi guys,
I am finding that reading the raw data off an SD in my embedded, that
the boot sector is not actually at address 0, but differs from card to
card (ie. my 64 MB has the boot sector at 4E00, and my 128 MB at C600).
Everything else before this is read as 0's.

huge box of ram? by
Paul Rubin
Is there such a thing as a relatively inexpensive box (up to a few K$,
say) that can hold a huge amount of ram, like 200-1000 GB? It doesn't
have to be battery backed or anything like that, but it should have
ECC or at least parity. The application is a high traffic database
cache.

NAS solution, Netapp or EMC by
darren
Hi all,
I am looking for a NAS server to work over NFS for 15-20 pieces of my linux

These servers will be involved in heavy reading and writing (about 30Mbps up
and down each server) of experimental data collected from a network of
probes.

How would you store 100TB data? by
[email protected]
Hi, I'm a student and out of my curiousness I want to know how data
centers usually store their data. Some mail provider liker Gmail and
Hotmail must have huge volume of data, even properly compressed. I just
can't imagine they could store it in hard drives. Is there any special
devices?

Homebrew Snap Server / Netdisk ? by
Jeff Sutter
Does anyone sell a SnapServer-like kit, where you provide your
own drive(s)?
I'm hoping for a network-attached, not firewire/usb device, in a very
small package, so it can go on the road, that allows drives to appear
as multiple 32g FAT32 partitions, so I can still access them from
Windows 95...

Help newbie with understanding SAN configuration by

could help me get through some of the initial rough spots.
The SAN is an almost fully loaded EMC (CX700, I think). From what I've

SCSI is limited to 2 terabytes by
Maurice Volaski
If you stick enough hard drives together, you can easily surpass 2
terabytes of combined space and if you try to connect them via SCSI,
you will apparently not see all your space.
That's because host bus adapters from Adaptec and LSI Logic can't see
anything larger than 2 terabytes.
