Looking to build storage of about 3TB -- recommendations? by
daben
Hi All
For my research I need large storage for satellite data files. I am
looking to build storage for about 1TB redundant array and 2TB
volatile array. I have looked around at snap servers or other SAN
solutions. I also have looked at scsi solutions but don't think that
scsi is economicable....

nav vs san by
[email protected]
I know this is a broad question, but here goes...
If performance were not an issue, what is better to stick to in an
enterprise.... NAS or SAN?
What is generally more flexible and easier to manage?

shared disk, two hosts (*without clustering* ) in linux by
javier_cobas
Hello,
i have been searching for a solution to have a shared disk (f.ex. SAN )
visible across two (or perhaps more) hosts, both of them able to read
or write on the disk . The data must be perfectly synchronized between
both hosts. (If no f.s. this should be managed by my application, but
then i...

RAID Controller Failover by
Steve Holly
I'm an IT admin starting to look at building a SAN for my company and I'm
curious if anyone out there can explain how some of the popular RAID vendors
(i.e. EMC, Chaparral, Infortrend) handle failover (resuming I/O with another
RAID controller after one has failed)? I'm mostly interested in...

Destroying Old Media by
Yoann Roman
Perhaps an odd question... We've found a set of really old DAT and DDS
backup tapes that we have neither the backup software nor the drives to
read/write. However, labels indicate these may contain sensitive data.
How would I go about destroying these w/o investment or illegal...

Teaming of paths by
Marcel
Hi all,
In a network environment it's possible to team/trunk multiple lines between
switches and/or hosts to one virtual single connection boosting throughput.
Is this also possible in a san environment?
I ask this because I've recently obtained a Dell Powervault 660F wich is
configurable with...

L1/L2 cache question by
v796
Hi,
An L1 cache is split(I,D) or unified. Most(All?) of the time an L2
cache is unified. Are there any processors out there which use a
split/unified L1 cache backed by a *unified* L2 cache?
Is there any motivation in doing this?
I am confused since IMHO, all the instruction opcodes ought to fit...

Pros and Cons of booting from SAN? by
ohaya
Hi,
This question may be in a FAQ, and if so, please point me to it...
We're considering the possibility of configuring some servers (a mix of
Sun and Wintel) off of a SAN (EMC) for a new system. I kind of
understand the potential positives, e.g., having images stored in a
central place, but my...

Sorry if this post seems a little naive but I don't do a lot with hard

I currently own a single (non SATA) drive computer running XP. I do a fair

i am comparing a emc ns 700 (4 data movers) with a netapp f 980.
the emc box scales to 30 tb while the netapp one scales to 32 tb.
seemingly both seem equivalent but emc is offering the advantage of
mixing serial ata disks with fibre channel disks in the same chassis.

Raid level write verification by
teckytim
Is it true that Raid levels like 1, 1+0, 3, 4 verify on the fly that
both the data write and the ecc write match while levels like raid 5
don't (with few exceptions on the very high end)? Is this dependant
rather on make & model?
TIA
