The Road to Data Mobility…

Storage hardware vendors like to refer to themselves as software companies. While it is true that most of them write storage software that runs on off-the-shelf hardware, most of them require that you buy their hardware to get their storage software. EMC, one of the first to claim to be a software, has evolved into a real software company. Other than the obvious software properties, like Networker or Vipr, an increasing percentage of...

ChalkTalk Video: [SDS] has to do More

The first phase of software defined storage (SDS) is bringing many benefits to the data center. Its abstraction of storage software from the storage hardware enables organizations to manage all their storage assets from a single view, along with a reduction of hardware acquisition cost. But SDS needs to do more. In its next phase SDS should also provide rich end-to-end, cross system analytics, and it should automate data placement...

Addressing VDI’s Fork in The Road

Organizations embark on Virtual Desktop Infrastructure (VDI) projects to drive down end-user operational costs and to enhance infrastructure security. These projects often evaluate well. During “test mode” there are a limited number of users, making it easy to meet their demands with a cost efficient, hard disk-based storage array. User counts increase as these systems move from test to production, and IT professionals face a fork in...

All-Flash Overkill for VDI?

Many vendors present all-flash arrays (AFA) as the cure-all for virtual desktop infrastructures. Indeed, AFAs can dramatically increase the number of virtual desktops that an infrastructure can support. AFAs also eliminate almost all performance problems; users love their lightning fast desktops. IT professionals need to ask themselves is upgrading to an AFA overkill and are they exposing themselves in other ways? To read the complete...

Designing Backup to Replace Primary Storage

Users and application owners expect that the systems they use will never go down, and if they do they will be returned to operation quickly with little data loss. In our article “Designing Primary Storage to Ease the Backup Burden” we discussed how to architect a primary storage infrastructure that is able to help meet these challenges. We call this design Protected Primary Storage. But this design can be expensive, especially if it...
