Your next storage will be invisible (for a while)

In the last two or three years I've talked a lot about "Flash & Trash." A two-tier storage strategy to best cope with the increasing demand of high IOPS and low latency from primary applications on the one hand, and high capacity, associated with throughput at times, on the other. This kind of need depends on the type of …

OSNEXUS: Storage upstart that funded itself before gaining angel wings

Take one ambitious Citrix engineering director who wanted to start his own storage company, sprinkle in $2m of angel funding and seven years later you find a IBM SoftLayer-blessed 20-person startup competing with DataCore. Nexenta and $100m+ funding, and other VC-backed software-defined storage vendors. How did that happen? …

Does it even make sense to buy a VTL today?

Blog I’ve never been fond of VTLs (virtual tape libraries). I like deduplication but it quickly became a feature and is not a product. And lately we all want more out of backups, don’t we? Data Domain did a great job in building a brilliant deduplication-based appliance in 2001, but that was 2001. And, while it lasted, having the …

ZFS comes to Debian, thanks to licensing workaround

The ZFS file system has come to popular Linux distribution Debian, but in a way the distro's backers think won't kick up another row over compatibility of open source licences. Ubuntu 16.04 added ZFS, despite pre-release grumblings from Richard Stallman to the effect that anything licensed under the GNU GPL v2 can only be …

A perfect marriage: YOU and Ubuntu 16.04

Before I dive into what's new in Ubuntu 16.04, it's worth pausing to reflect on what's missing: Scopes online search, now off by default. That means no more potentially socially awkward search results when all you really wanted was to open Brasero (speaking of which, Brasero is gone too). Scopes, introduced four years ago, …

Ubuntu 16.04 LTS arrives today complete with forbidden ZFS

Canonical will today (April 21st) launch version 16.04 of its Ubuntu Linux distribution, Xenial Xerus, the new long-term-support version of the project.

Scale-out storage: Proprietary? Commodity? Or both?

There is no doubting that scale-out storage is now thoroughly achievable. Indeed, scale-out is pretty much the norm for object storage, plus it is now the primary option when it comes to huge volumes of file-based NAS, where scale-out means a highly-scalable file system that supports clustering. It is growing in popularity for …

If Dell and EMC really do merge, expect massive, bloody consolidation

EMC/Dell deal We're far from convinced that Dell acquiring and/or merging with EMC is a good idea, but if it did what kind of entity would we be looking at? The crux of the matter is just how much overlap Dell is willing to endure. And the answer may be "lots". Dell's made much in recent months of giving customers choices. Exhibit A is the …
