The Case for Persistent Full Clones: A Better Alternative to Linked Clones for VDI

Most of the VDI case studies floating around the internet, and in fact most of the truly successful VDI implementations, have used Linked Clones to support task workers. Task workers, who run a small number of applications and may share workstations in hospitals, call centers and the like are the low hanging fruit of VDI.  They’re low on the corporate totem pole and don’t have the intimate relationship with their PCs that executives and other knowledge workers do.

This Technology Report, produced for GreenBytes, makes the case for solving the VDI storage problem not in the VDI environment via Linked Clones but in the storage layer with real data deduplication.  It expands the argument Howard started on his NetworkComputing blog Solving VDI Problems with SSDs and Data Deduplication.

Flattening the Data Center Network – Ethernet Fabric Revolutionizes Data Center Network Design

Over the past decade or more we’ve used basically the same Ethernet technology in the data center and across the campus.  This however has been changing as new Ethernet technologies directly targeting the data center like VM migration detection and fabric technologies come to market.

When Brocade briefed us on their new VDX series of data center switches Howard’s first reaction was “the fabric means I could build a moderate sized data center without the expensive core swiches”. The folks at Brocade thought it was such a good idea they commissioned this Technology Validation Report to compare the cost and complexity of conventional and Cisco Nexus based solutions to a coreless VCS fabric.

The Storage Efficiency Imperative

This Technology Report explores the issues revolving around storage efficiency technologies including snapshots, data deduplication and compression for primary storage. It then looks in detail at how SolidFire has used these techniques in their all solid state. Scale out storage system.

Amplistor Delivers eXtreme Performance Object Storage System Ingests Data at Near Line Speed

As the tsunami of unstructured data continues to inundate data centers object storage systems have immerged as a solution.  Many users however are concerned that object storage systems that use advanced technologies like erasure, or even better dispersal, coding to protect data may not be fast enough for their needs.

For this Technology Validation Report Howard flew off to Amplidata’s headquarters outside Ghent in Flanders, the Dutch speaking part of Belgium to run an Amplistor system through its paces.  Turns out for larger object sizes Amplistor can ingest and return data at well over 1Gbps.
