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 am exploring SAN options at the office and keep reading that EMC is the best. I am not doing FC, but am looking at a CX300i. How good is this product compared to the cheaper HP, Lefthand, and other options? Is their reputation worth the extra cost for maintenance, support, and quality?

Hi to all... I've bought an used LTO HP Ultrium 1, and i want to know how much it was used, i've tryied with the hp l&tt utility (versions 3.5 SR4 e 4.4), but it doesn't say me nothing about the usage. If i well remember with an older version of the l&tt i was able to read that data (with a dds...

Hi, I have a 1.4 TB Volume exported over NFS, accessed from a Linux NFS(v3) client. I have to fill all indoes on this volume. One way of doing it is to create so many files which is time consuming . One more option to use is Snapmirror/Replication technologies to create this Data set. Anything else...

I started thinking about this after a conversation with an acquaintance who runs a large database driven website. Currently he has only one data center, all writes from all over the world come there. So he's planning 3 things: 0. Open up more DCs. 1. Some sort of geographic identification of an...

A recent document on bitsavers http://bitsavers.org/pdf/dec/competitiveAnalysis/Engineering_Strategy_Review_Mar82.pdf has an estimate - in 1983 - of worldwide "large disk" production (including IBM) at about 60,000 units. (I get this by adding the "OEM numbers" to the "IBM numbers"). Capacity...

This is the second time it is happening. I have lost the LaCie drive. It is not listed anywhere. It has two partitions on it with many thousands of files. The first time it happened, I disconnected everything and then reconnected everything, and the drive came back. I did the same thing 3 times...

I'm regularly a PC user but have just purchased a second computer which is a MAC. I backup my data to a 500GB External HD with 5 NTFS partitions of 100GB each. Each partition contains a different type of date, ie Music, Videos, Docs, etc. I used separate partition to avoid the risk of corrupting...

Over last couple of years the certain types of data is exploding in our enterprise (probably true for others too). These include source code, binary images (and many many variations of those), all kinds of documents (word, excel), wikis etc. These are kept like regular files (available via NAS)...

X-No-Archive: Yes Anyone know what's the modern high capacity rewritable media that can be written in a manner like a floppy drive using drag 'n drop that is very reliable? I'd like something that can be permanently archived and can be used over and over again without a significant reliability...

Storage Gurus, We have been using Netbackup for years, and have used it for archives. But our end users are not comfortable with this solution. Saving the bplist output is not an elegant solution for them either. They loose track of where their data was when it was archived and so are unable to...

Hi, In a SAN enviornment, can two servers have access to the same storage device at the the same time? I want to implement a failover, one server doing all the writing, the other only read from the disk. If one server goes down, the other will do both. Is this possible and normal way to use...

I have the option of using 146GB drives (instead of 72GB) on my SAN (FAST700), but am afraid of disk contention issues and rebuild times (raid 5) if one of my drives goes bad. Does anybody have any opinions on these matters? thanks

Hi group. We are in the process of buying a SAN for a small server set-up. We have planed to use 24 x 72 GB disk drives in the SAN and the SAN models we have been looking at are the HP EVA 3000 and the IBM FAStT 600T.

Has anyone seen this? we are new to network appliance, our company has just decided to start getting these units instead of other SAN/NAS solutions that would have a windows kernel rather than unix. It started when one of our developers was alerted to errors in one of their applications. This...

I have a few questions but let me first give a quick background. I have an MS SQL server that is having an IO bottleneck. Disk space isnt much of an issue since the database is only about 10gig, but I'd like to improve IO by increasing the amount of disks and channels. I see 2 options: 1. SCSI...

Hi all, I'm currently monitoring this ng because I need to learn some things about san. The differences between SAN and NAS are clear to me so that does not need any additional explanation. My interests in SAN were raised when I received some hardware from a friend and started to read about it....

I have a nice new server with 15,000RPM SCSI drives in a hardware RAID 5 configuration. I may be wrong, but I don't think it's performing properly at all. The question is, what's reasonable? When using large (500MB) files to swamp out cache effects, I'm getting roughly 12MB/sec (it varies quite...

Hi! We've been using ArcServe for NT/W2K for a number of years. Our software vendor is pushing us to switch over to BackupExec ("it's got a clearer roadmap"). I'm trying to analyse the sales bumpf from both companies to work out if one is clearer better than the other. Have any of you guys used...
