Server and StorageIO, @storageio The EMC2 Advanced Software Division (ASD) recently announced (more here and here) enhancements to its ViPR (v1.1) software-defined storage management solution, as well as a new version of its Storage Resource Management (SRM) product (v3.0). First, keep in mind that SRM, in the traditional server and storage world, means systems or…

Nutanix OS 3.5: Deduplication, New GUI, SRM, Hyper-V Support

Nutanix, one of the fastest growing IT infrastructure startups around, shows no signs of slowing down with their release of Nutanix OS 3.5. For those not familiar with Nutanix, they offer a truly converged virtualized infrastructure. This generally consists of four nodes in two rack units of space, where each node has CPU, RAM, traditional fixed disk, SSD, and Fusion-IO flash built in. Their secret sauce is really NDFS, the Nutanix Distributed File System, built by the same folks that created Google’s File System, as well as a unified, hypervisor-agnostic management interface.

Whether you use replication as a means of disaster avoidance or disaster recovery, replication of your virtual environment between hot sites has always been a win. With current technology it is even possible to replicate to a replication receiver cloud which could provide a measure of business continuity as well. So who are the players and who provides what service, and how do they do it?

Security in the cloud and the virtual environment is ‘all about the data’ and not specifically about any other subsystem. It is about the data. As such the data has something it knows (the contents of the data), something it is (its signature), and something it has (its digital rights) and since it has these three elements, the data has all it has identity. However, protecting the data requires us to put things between the data and the real world such as firewalls, and complex role based access controls, as well as methods to replicate the data to other locations in a non-intrusive mechanism. The goal to such replication could be to ensure multiple sites have the same data (such as a hot-site) or to have the data available in another locations in case of disaster.
