Welcome to our October eNewsletter, which includes an interesting – and possibly controversial – discussion of the pros and cons of ‘always on’ deduplication. “If your storage system isn’t intelligent enough to read the metadata and perform inline deduplication, adapting to any given workload you throw at it, you probably have the wrong bit of hardware in place,” argues Kaminario’s Mick Bradley. “As we move towards computing environments that are even more data-intensive than ever before, what you need is a system capable of only applying deduplication to data that it will absolutely work on.”
The growth of all-flash in the enterprise has seen deduplication enjoy something of a renaissance in terms of storage infrastructure strategy. But it appears that it is not the panacea that some vendors have suggested. While virtualised environments in particular appear to be ideal for deduplication, it looks like it could be doing more harm than good in certain types of application. All de-dupe is not the same, seems to be the message.
