Hi, We are thinking of purchasing the EMC Clariion CX 600. We are going to store our databases on it. We are told that its easy to make a clone of a LUN. We have a 200 GB database that we want to clone very hour. The cloned database will be used as read-only database for clients. Has...

I have what may turn out to be a very basic question about connecting a Dell server to a DataDirect Networks SAN. I should mention that all of the existing setup was done by someone else, and although I have the DataDirect User's Guide I have no real SAN experience to fall back on. The gist is...

Does anyone have a solution to the following problem: requirements: 1)A storage unit-system 2)with a data transfer rate of up to 5 GByte/sec (yes that is Giga) 3)Storage capacity of up to 20 TByte. 4)Preferably an off the self solution (though suggesting an architecture of eg. a specific raid...

Hi all, I am trying to get an FC tape library configured and I'm almost there but for one issue - I can't access the tape drives very well. Here's what I have. Sun Enterprise 250 with Solaris 9 JNI FCI-1063 PCI HBA with JNIfcaPCI (v2.6.13 driver) package Veritas Netbackup 4.5 MP6 Quantum/ATL P2000...

Hi guys, I've written a short guide to the most common levels of RAID in use, mainly so people new to computers and storage solutions can get to grips with it. I know I would have found a guide useful a year ago when I was new to RAID. I know there are many resources out there, but I tried to make...

The company I work for has NetApp file servers and according to our IT people, they can't keep proper time using NTP. Why not? Consequently, builds across network drives are a nuisance. Apparently the clock drifts fast and our ops set the time slow to compensate. We don't have to have the...

Hi folks, I have a QUANTUM DLT7000 1624. It's mounted internally. The base of the unit gets hot. Too hot to touch for more than 5 or 6 seconds. Is this normal/expected/unusual? -- Dan Langille The Technical BSD Conference - http://www.bsdcan.org/

I posted a little while ago concerning failover solutions for a Windows 2000 server. Unfortunately, budget limitations prohibit the solutions recommended. So....here's our situation now....have a 2000 member server that needs to be replicated to a seperate server (no shared storage...just local...

Hi, Is there some information on what the file system created by NTBackup looks like. I am new to storage technologies but I am familiar with FAT and NTFS file systems. If you can point me to the right source or explain the overall architecture, I'd be grateful. Thanks, Ahmad

Hi, I would like to make a two-nodes cluster from standard PCs and i'm looking for a SAN solution to give these nodes a shared storage subsystem. I'm not a hardware guru so please forgive me 8). It should be able to have 8 hot swap bays and the maximum capacity should be 2TB. I'm interested in...

Hi: A very happy EMC Clariion CX customer says that he will not consider buying an IBM FAStT because in case of power failures, the CX automatically downloads unwritten data from cache to disks using their self power cells. Does anybody know about workarounds to have this kind of safety with IBM...

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.

Hi, I've got a problem using hardware compression with a Seagate STT20000A IDE Travan TR-5 tape drive. I am using the backup program that is native to Windows 2000 Server and can't get more than 10GB on a tape. These tapes should handle up to 20GB of data if compressed. I have selected the 'use...

How can I query TSM to find how much storage is currently in use now (tape) for all the files (corporate-wide) that are backed up (under TSM's control)? I was just asked a question do we want to get rid of the tape robot and move to JBOD instead. Thoughts on doing that kind of move? Mike

I need to architect 2TB of disk storage with absolute maximum read capabilities. I have an application that sequentially reads and analyzes large flat data base files and the faster I can read them the faster I can analyze. CPU and memory are not a factor - currently the disk "reads" are my...

There is a problem the users were warned about dealing with sharing files on windows boxes over a T1 between North America and Europe. Now I'm trying to find possible solutions on how to fix this problem. One idea I think I've heard of is a filesystem that can be shared, like AFS, that exchanges...

I am trying to understand my options for a project that requires a lot of low-cost storage, but limited access. It will be a low-usage streaming video application. The video will not need a SLA guarantee, but I would have to find a way to recover *when* disk(s) crash. I was thinking that I could...

my underestanding is tht netapp snapshots are almost a zero penalty scheme while those with emc put a heavy penalty. here is why netapp snapshot scheme block a from active file system has to be changed to a1. the operations are as below find a new free block which is very fast due to...

As a home user I am in need of a budget solution. As a RAID newbie I'm in need of a little bit of advice. The background - I need to get a lot of data onto a lot of drives as quickly as possible, and it has to be done via 100Mbps ethernet. The ethernet is my current bottleneck and I intend to...

Hello, Navisphere is showing a hosts as unmanaged due to host agent not reacheable. For some odd reason, the host agent seems to be resolving incorrectly. The hosts in the navisphere is referring to the private IP address on the host. That should have been the public address. Since private IP is...
