Re: [Veritas-bu] Quantum's DXi Series of Dedupe Appliances

We have run the DD460 and DD690 (and continue to run the latter). Back in November we got the DXi 6500 to replace our two DD460s.

Performance wise I really like the Data Domain products – they do the compression they promise. So far I’ve seen nothing with the DXi 6500 that leads me to believe it isn’t just as good. We use it for our main Production (4 TB) DB and other large backups. The PROD backup is finishing in a window shorter than it did on the DD690. We went to the Quantum stuff as part of a big data center move that gave us better pricing for the DXi than we would have gotten on a DD not for any technical issues with the DD itself.

Subject: [Veritas-bu] Quantum's DXi Series of Dedupe Appliances

We are a NetBackup shop looking to implement a disk based backup infrastructure utilizing data deduplication, to evolve our tape infrastructure to more of a secondary copy, archival media. For the central data center at least we are leaning towards a deduplication appliance solution. Of course we're taking a serious look at Data Domain. Their Jan 18 announcement's performance numbers for the DD890 and the Global Dedupe Array are impressive.

I'm intrigued, though, by this lesser known player, Quantum. Their DXi8500 certainly boasts more modest performance numbers does than the DD890, but it has three features that catch my attention: 1) SAS drives; 2) Direct-To-Tape; 3) The options to inline, post-process or not dedupe at all a segment of data.

I'd appreciate any comments from folks who run or have run a model from Quantum's DXi series, as well as from anyone who evaluated them vs. Data Domain. Thanks.
