OS driven Software-Defined Storage (SDS) with Linux

In the tech world, a “layered cake” approach allows IT shops to enable new software capabilities while minimizing disruption. Need a new feature? Add a new layer. But like “too much of a good thing,” this approach has caused the IT stack to grow over the years. Software layer bloat and complexity can lead to […]

Linux Data Deduplication and Compression: One more reason to use block level data replication.

Having recently returned from my 6th Red Hat Summit (RHS), I’m writing this blog to answer a common question: “why replicate at the block level?” Using block-level replication, we can easily add high availability or disaster recovery features to any application that doesn’t natively support them. The most frequently asked question we heard at RHS […]

Dreaded Day of Downtime

Some say that no one dreads a day of downtime like a storage admin. I disagree. Sure, the storage admins might be responsible for recovering a whole organization if an outage occurs; and sure, they might be the ones who lose their jobs from an unexpected debacle, but I would speculate that others have more […]

No one likes losing payroll data, shipments, customer information, financial transactions, or […]

FINALLY! Open Source Deduplication for Linux!

Pair this deduplication software (which also has optional compression) with our DRBD software, and you get extremely efficient, low overhead, data replication. The problem is Permabit built a solution […]
