On several occasions I have seen situations where faulty UPS's caused servers wtih RAID 5 arrays to reboot continuosly which caused corruption to either the RAID array itself or the file system. I am considering recommending RAID1 whenever possible because I suspect that it would be more resillient...

A couple of years ago I bought 4 external HDD's, Maxtors, to increase storage capacity on some machines (and offer portability) in my business. After 2 failed in short order I returned the other 2 and swore not to touch external drives again. A couple of months ago my IT supplier convinced me...

Hi, How do ILM products like kazeon that migrate files to alternate storage deal with Windows Explorer that do directory listings and try to open each and every file to read the data (for thumbnails)? Will this cause Kazeon to restore the files from alternate storage back onto the primary...

I work for a consulting firm, and have begun to do troubleshooting on small SANs, mostly HP MSA1500cs based. Many times the problem the customer is talking about is some vague intermittent slowness issue or something like that. In cases like this, my troubleshooting goes something like this: 1. ...

Hi, I'm in need for (budget) storage at home. After doing a little research i decided to build my own NAS server. I've got an "old" AMD Athlon XP 2400+ with one GB of ram, so that will be more than sufficient i guess. I've been thinking of doing the following, but i wonder if it's the best way...

I'd like to play around with a small inexpensive SAN at home. Storage capacity or performance is not a concern something like a 4 or 5 year old EMC, HP or IBM box. Any suggestions?

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...

I want to backup my data in a remote location. The total size of the data is about 500GB but the incremental data is comparably small. A commercial online backup service is one option but I much prefer a backup on a family's computer on a different continent. In any case, here are the...

Do you remember back when we had to specify the Cylinders, Heads and Sectors (CHS) in the BIOS Setup when installing a new hard drive? There was a 'drive type' table that had ready-made sets drive parameters to pick from. You picked one that was the best for the drive and your choice of...

Is there a decent Windows based backup program that allows clients to push their backups to a central server using an agent technolgy rather than having the central server contact the distributed agents and pull the data? The problem with the pull model is that you often end up having a...

Hi, What formats are the full and incremental dumps from a NetApp OnTAP system in? As in, is the backup data in some proprietary NetApp format? Also, what is the difference between NDMP and SnapMirror? Dvy

What's the best SAN solution I can get for $20K? Planned uses include storage for student data (we are a school district) VMware server virtualization (store virtual machines here for failover) Email Archiving Possible Electronic document storage I realize my knowledge is limited and that I am...

My coworker just gave me his used Snap Server 4000. I've connected it to my home network and everything is working correctly, but it's asking me for a user name & password to access the device (either to gain access to the drives or for configuration). He doesn't remember what users he created,...

Hello, I am shopping for a 120 TB SAN solution which will probably be accessed by a cluster of servers through a shared filesystem. Being new in this field, I would welcome some pointers on where I should start looking. I have already find some handy info through archives of this list, but I...

I have a UNIX server that hosts some fairly large Informix tables and recently the servers performance has degraded quite dramatically. After investigating further it appears that this is down to a storage bottleneck, the server is around three years old and I just upgraded it's CPU's (dual...

Hello NewsGroup, I've seen some posts debating the merits of building your RAID or buying your own RAID. I like to point out the benefits of purchasing your storage needs through Real-Storage. I think the benefits are very clear. Thanks for your time.

Or do you have to purchase Clariion support seperately?

If you have a given sector, say 5000th sector (logical), how can you get the physical location in: platters, tracks and sectors?

Currently we are experiencing alot of problems with tape backup and I have had some thoughts. Is it possible to purchase a SAN with a huge amount of disk space (say 1 terrabyte), then partition the SAN storage up and then backup the data from various servers to specific partition on the SAN. This...
