Comparison – Hybrid Cloud Data Protection – Mechanisms

This is the first of many comparisons and commentaries on data protection within the hybrid cloud. We are looking at the mechanisms used to achieve data protection. Mechanisms—how boring—yet from an architectural and data management view, mechanisms become increasingly important. The mechanisms available can impact the costs of your data protection. One example: it is often thought that data protection is instantaneous. It isn’t. It has a window of execution measured in hours, not microseconds. If you need microsecond data protection, you may need other tools to fill that need.

The first things to decide are what you need in the way of time to recover your application (recovery time objective, or RTO) as well as how much data loss you can stomach during recovery (recovery point objective, or RPO). RPO determines how often data protection should be used, while RTO governs how soon recovery will be completed once started. This pair of critical factors will control what mechanisms are important within your organization. Beyond those two, there are other, equally important mechanisms that influence the types of recovery mechanisms in use.

IO IO it is off to Storage and IO metrics we go

By Greg Schulz, Server and StorageIO @storageio

IO, IO, it’s off to storage and IO metrics we go shifting gears a bit from the recent four part series around SSD topics for physical and virtual environment. A while back I did a post about Why VASA is import to have in your VMware CASA along with another piece about Windows boot IO and storage performance impact on VDI planning. Among other things those two pieces have in common is a theme around the importance of storage and IO metrics that matter.

Desktop virtualization, a year in review

The desktop virtualization year opened with a bang at CES with the explosion of vendor announcements introducing the next generation of mobile tablets.  The obvious winner this year being Apple and the iPad but with many more vendors showing off Windows-based tablets including  HP, Archos and Pegatron, as well as Android tablets from manufacturers such as Archos (again), Compal, Dell, HP (again), and Motorola.  The key challenge of course being the delivery of existing enterprise applications onto these platforms, something that’s desktop virtualization and presentation virtualization is ideally suited for.  The inescapable consequence of this was a steady stream of announcements from Citrix, VMware, and Wyse as they leapfrogged each other’s announcements on availability, functionality, and usability of their respective mobile tablet client offerings.  The level of competitiveness here producing major benefits for potential adopters as each strove to outdo the other in terms of user experience innovation and performance.
