We're currently about 2 weeks in to eval of a 580. I've been really impressed with the compression so far. We've been doing test backups of our 2.5Tb SAP instance - after the first backup the post compression size of that was 500Gb. We've since been throwing a mix of data at it, from Windows file server, Exchange, misc Oracle and SQL, and we're up to about 10 to 1 compression.
My biggest issue with the device is the hard limit on how much data it can process. No matter what I/O options you go with - i.e. VTL or GigE - you'll always be limited to 220Mb per second. No matter how fast you get the data there, that's as fast as the DataDomain box can process it. Getting a tape based solution to match these speeds is quite easy - a properly configured fibre based tape library solution with, say 8 LTO3 drives, could easily handle 500+Mb per second. Obviously comparing the two is kind of an apples-and-oranges thing, but what I'm saying is that I don't like having to max out a products capabilities just to get it to work as I want. I'd rather have it be able to handle whatever I throw at and have extra capacity to spare. Especially for the price tag that the DataDomain devices carry. +---------------------------------------------------------------------- |This was sent by [EMAIL PROTECTED] via Backup Central. |Forward SPAM to [EMAIL PROTECTED] +---------------------------------------------------------------------- _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
