Listen up, VMware admins: If the array won't support it, VVOL won't help you...

Comment VMware's VVOL allows VMware admins to manage storage arrays through the API – but it doesn't necessarily mean they get to use all the VVOL data services. PernixData's Tech Evangelist Frank Denneman told us: "The interesting bits in the VVOL announcement are the supported 'Data Service' capabilities. As VVOL is an API, you can …

Dedupe, dedupe... dedupe, dedupe, dedupe: Oracle polishes ZFS diamond

Oracle's ZFS is widely lauded as a great file system even though several suppliers that use it for their own products have replaced its deduplication code with their own. One such was GreenBytes, a startup which developed an all-flash array for virtualised servers and focused on VDI. It switched to a software-only model after …

Is HP pulling a fast one on deduplication?

Is HP pulling the deduplication wool over our eyes by claiming its dedupe box can run at 100TB/hour while EMC's best rate is 31TB/hour? Should a 4-pool dedupe system realistically be compared to single pool design? Yesterday at the HP Discover event in Las Vegas, the company announced its Store Once Catalyst software and B6200 …

The HP 3PAR StorServ 7000 series arrays

What's that you say? HP's going to do WHAT to 3PAR StoreServs?

Blocks and Files Rumours circulating today suggest HP is going to add full data deduplication to its StoreServ (3PAR) storage arrays. Deduplication identifies and removes duplicated blocks to prevent space being taken up by repetitive content. With a flash array, this also helps to reduce the amount of data written to the silicon which prolongs …

Deduplication: a power-hungry way to streamline storage

Windows Server 8 is coming, and it is bringing storage enhancements with it. Data deduplication in particular has caught my eye: it is something I have wanted on my Windows file servers for a long time. This technology is nothing new; ZFS has had deduplication for a while now, and this technology is (experimentally) available …

Storagebod Storage marketing is one of maddest and craziest parts of the technology industry: there are so many claims that don’t necessarily stand up to scrutiny and pretty much all of them require the caveat: "It depends…" It is very important to understand that it really does depend on a number of factors. For example, when your flash …
