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

Hallo, i hope, i am right here!? Have anyone experience with Allnet All6200 NAS or any clone like Longshine LCS - 8200, Netronix NH-200. I'm interested in activating telnet on it and so on. In the moment i found only this german site to start something:

I are trying to backup a SQL database using multiple streams. I can shutdown the database using bpstart_notify.bat, both streams kick off and run, however when one stream finishes it restarts the database using the bpend_notify.bat script... This of course makes my...

Hi, We're going to be purchasing a database server from IBM. Although the database itself will be housed on a 10-drive SCSI-based external storage unit, the operating system will reside on two drives housed in the server itself. The drives will be mirrored (RAID 1). I noticed that the server quote...

Hey. I'm in a situation in which I'm having to bone up on a bunch of VxVM stuff w/o access to a system: doing it all by reading Veritas manuals and SunOS/VxVM man-pages on the web, and taking notes (which helps me learn). A few weeks ago, I looked for Veritas-dedicated Usenet groups and found...

We are seeing a bunch of problems with LTO media over the last couple of weeks and months. Anyone know where I can find a comparison of LTO manufacturers reliability stats? We have seen a bunch of Imations fail over the last couple of months. Has anyone else seen this?

Hi First of all, what is the difference between a RAID controller and a RAID card. Promise (www.promise.com) seem to have two product ranges of the above products. And also, what is the best RAID controller/card (not just promise) to go for, that won't slow the performace of my PC in any way,...

hello I am looking for a cheap NAS for our firm. I have found Open-E NAS ENTERPRISE (http://www.open-e.com/index.php?g=product&lang=eng&aid=151). What do you think about this solutions?? Anyone use this NAS??? Maybe another solutions?? --- Best Regards, Halemb

I am trying to dump raw blocks from a floppy tape device to disk file in a DOS/Windows environment. I am having little luck. I am unable to dd with mks as the floppy driver doesn't perform with the tape drive. Obviously I can't treat it like a scsi device. Does anyone know of any functional...

Only if you want to ever recover anything. ;) You should also be backing up the database every day as well. --- W. Curtis Preston Author of O'Reilly's Backup & Recovery and Using SANs and NAS VP Data Protection GlassHouse Technologies

Hi, I wish to create a backup solution that will backup all my home data (nightly/incrementally) off site to my brother's home network over the internet using broadband. I'm assuming that I will need to connect via a VPN to join the two networks. I will use software to capture the dynamic IP...

Hi All, Apologies in advance if I'm being particularly simple. With SSD drives coming down in price, and becoming a standard feature in Intel's forthcoming Centrino 2 architecture, will this make caching redundant in operating systems? Current operating systems such as Windows XP and much more...

hi, Can anyone recommend a fibre Channel hub which will provide failover for a W2k cluster with a Metastor E2400 and QLA2300F/66 2Gb PCI HBA's. Would a IBM Netfinity Fibre Channel Hub - 3523 or Emulex LH1005 do the job? I'm looking for something less expensive than 8 port switch. cheers

Hi all. I have a second hand Storagetek D173 disk array, that I am struggling with performance (or lack of) It has six 10k, 73GB disks and dual 1Gbit controllers (everything is fibre) Currently all the disks are configured in RAID0 (it was RAID5, but thought it might have been that slowing it...

I'm wondering how much difference there exists between SATA and, say FCAL drives when it comes to robustness. I'm talking drives that will be more than 20% busy with seeks, always spinning, in news servers. I've seen a too-high rate on FCAL disks used as JBOD - about half the drives developing bad...

I'm starting to feel like an idiot for not being able to get Win2K to 'eject' an external USB drive that I got as a Christmas present for my wife and daughter. Each time I request that it be 'ejected' (to make it safe to remove it, presumably by flushing Win2K's internal file cache to it) it...

esto es la prueba

I am close to making a big investment on a Cisco SAN implementation. Anyone played with MDS series before. Your feedback is appreciated.

I have a 30gb Maxtor drive with a small problem. I'm not sure how I did it, but drive suddenly shows up as unformatted. Using Partitionmagic, I was able to put a small partition on it (as a test), and disk editor says that my data is still intact. How do I get it back?

Hey - I figured this was the perfect place for my question. I'm in the process of studying up for the SNCP FC-Level 2 exam. I know when I looked into this about a year ago Tom Clarks first book was the one to read. Is that still true ? I'm just a little nervous and want to make sure...
