I'm struggling to find any web forums that cover servers and storage and that sort of thing. Long story short we have to change a bunch of kit at work including our main filserver. Ideally we'd like a SAN solution but they cost a small fortune. Assuming a SAN is out of the question, we're...

Background info : EMC Celerra IP : 10.36.96.217 Backup Server IP : 10.36.96.208 Backup between the two works fine, however has to go through a switch and drains the main bandwidth available from the Celerra, so what I have done is directly connected a port on the Celerra via cat6 to another...

We have two Iomega P800 NAS servers running cut down edition of Windows 2000 server. Both have dual 2.4GHz and 1GB RAM each. Server A is online and has 1TB capacity. Approx. 300GB of the storage is currently occupied. This server is used to store customer files. We regularly backup this server to...

Has anyone managed to disable the hardware compression on the Exabyte VXA-2 tape drive ? I just maxed out the tape at 116 GB. I suspect that I might get better compression from my Backup Exec software. Thanks, Lynn McGuire

Is it possible to disable hardware disk cache? Not the software cache. I can read files with no software cache, opening them without buffering (FILE_FLAG_NO_BUFFERING) but I can't avoid the hardware cache. Is it possible to get the hardware disk cache size? Or even disable it? Thanks a lot.

I've just setup 4 scsi 10g disk on a LVM volume, and created one partition which comes up to be 36g. My question is, what happens if one of the hard drives fail? what does LVM do? does the entire group die? I am running ubuntu dapper on a intel pentium III 800mhz server.

Requesting information (or links to information) regarding on how to backup to multiple DVDs via disc spanning. Thank you, Ken

Hi, Lately I have prepared disk & disk array calculator. It's a tool to calculate expected storage performance and capacity. I've put it in the net: http://www.wmarow.com/strcalc/ . Try it out. Any feedback I will appreciate. /Marek wmarow at gmail

I've been trying to add two disk packs currently on the shark to one of the intel (windows) servers. I have defined each disk pack as a raid 5 individually. I couldn't find a way to raid the two disk packs together. Then I tried to add the volumes to the intel server. The volumes were added...

I read in a recent PhD dissertation: "Due to the higher complexity of micro-actuation and track-tracing required during track and head switches, increased disk storage density actually decreases the disk bandwith." Wow! My reference figure for that matter was that disk bandwith keeps increasing at...

The frequency with which disk sectors become unreadable seems to have remained relatively stable over the years, though one might hope that it will decrease significantly with the expected move to 4 KB sectors (at least if correction bits per sector increase somewhere nearly...

Guys I have a situation where i have to play with a NSeries 5000 gateway. This gateway is serving san disks from ESS now and we have to replace this ESS with DS8300... I never worked on these gateways , so searching for some documentations and guides...appreciate any links

Mine is a disk based backup/restore product. It is multithreaded, which means many backups and restores are happening simultaneously. The product has basically three types of interactions with the disk. 1. Read. This is synchronous. Most reads happen on mounted shadow copies (using...

I managed to get my hands on a Clariion CX600 whihc I have running in my basement right now. The only thing wrong is that I have one bad drive. I found a replacement for $100 but it looks like it has the wrong firmware on it which is preventing the Clariion from recognizing it. The firmware version...

I need to build a new database server (SQL server on new HP or Dell hardware) and I have a question about the disk subsystem. I want to separate the OS, logfiles and database files on separate disk arrays. The OS will be placed on RAID1 on the machine's internal RAID controller. I intend to install...

I am interested in our thoughts and comments on a raid system that would be used for storing archival data. Requirements: - maximum capacity - minimum dollars (but not cheap, as in poor quality) - minimal performance need (the data mostly just sits there) - must provide "phone home" capability to...

Can some one point me to a good resource that point out the differences amonng the disk technologies? (or) good brief resources for each of these (ATA,SATA,SAS) Thanks a lot, S
