Has anyone used Clariion LUN Migrate function on-line? by
Doug Freyburger
Folks,
I need to build a 400 GB LUN for a snap clone BCV cycle.
My Clariion is nearly full so I did some space reclamation
and now I have 300 GB, 200 GB and 185 GB free in 3
separate RAID Groups. Happy Murphy's Law that none
of the freed LUNs were in the same RAID Group.
I know how to...

Sharing SAN Partition with multiple Linux Clients by
Alan Miller
Hi,
We have an IBM DS4000 SAN array. We want to have two linux servers
attach to one partition and both be able to read/write to the disk at
the same time.
We created a host group and put both hosts into the same group and
gave that group a mapping to the logical drive we want them to share.
They...

QLogic QLA2312F Card by
Will
Does anyone know what the QLogic QLA2312F card is? QLogic says it is OEM
for HP. HP says it isn't their card at all.
On insertion to any Wintel PCI system, the entire system freezes and refuses
to even start up the BIOS.

time to read meta data on 300TB by
[email protected]
Hi,
How long would it take (on a decent NAS filer) to read the meta data
for 300TB of data via NFS?
I know the answer varys for different vendors, but im just looking for
a ballpark... Assuming average file size of 1MB, which is the case in
my environment, I estimate I have about 300 million...

Cabinet to store LTO tapes by
Rob Nicholson
I have the "honour" of keeping our off-site tape backups but I need the
drawer space back :-) Anyone know of a company who sell tape cabinets with
drawers that I can screw to the wall?
Thanks, Rob.
PS. We're UK based.

MAID systems by
Curtis Preston
You power down/up your laptop (and maybe PC) all the time. What's so
hard to believe?
Each drive has specs for how many times it can be powered on/off in a
lifetime, and they keep track of that and don't exceed it. They also
keep track of how long it's powered off, and power it on after...

Reading disk temperature from SMART info by
[email protected]
I recently bought an external WD MyBook 500 GB drive. The enclosed
software (WD diagnostics) enables me to read drive's SMART parameters
(I thought this would only be possible with internal drives) which is
good.
However, I'd like to know how to translate its "Temperature" parameter
into something...

Sony AIT-1 IDE tape drive performance by

I'm trying to find some performance references for my Sony tape
drive. My backups are taking 12+ hours and only getting 80Mb/minute
throughput.
Is this typical for IDE tape drives?
I've explored the usual...updated IDE drivers, updated Sony firmware,
updated Sony tape drive driver. Same...

there has to be a better way, or we are stuffed! by
[email protected]
Company I work for has a SAN of about 50 TB.
It is configured as 4 logical disks. So when there is a
failure, that logical disk is out of action while
the RAID rebuilds itself. "Hot swapping" doesn't
help much when 1/4 of the system is paralysed for
hours afterwards. It seems about once a month...

MAID systems by

Is anyone here running a MAID system? Copan is the first one that

I'm interested in experience with a dense HDD system that powers off

In theory and concept this is a good thing, particularly with archive

space consumed by raid6 by
[email protected]
How much overhead does raid6 add? If I had 300GB of data, how much
overhead would be added by the raid6 implementation? Does this also
depend on how much data I have? Will the overhead change if I had
more than 300GB, say 600GB?
