Digital VMS White Papers

The Virtualization Spectrum From Hyperthreads to Grids

Overview Modern Virtual Machines (VMs) can be opaque to conventional performance management tools because VM technology has surpassed standard measurement paradigms. The paper attempt to ameliorate that problem by; observing that disparate types of VMs lie on a discrete spectrum bounded by hyperthreading at one extreme and GRID-like services at the other, and; recognizing that poll-based scheduling is the common architectural element in many VM implementations. The associated polling frequency (from GHz to pHz) positions each VM in its respective region of the VM-spectrum. Several case studies are analyzed to illustrate how this insight can make VMs more visible to performance management techniques.

The Ovum View: 3G in Malaysia

In part, the allocation of only two blocks of spectrum can be viewed as part of the long-awaited process of telecommunications industry consolidation in Malaysia. So what does the allocation of spectrum mean for Malaysian communications?

Roll up, roll up, get your broadband spectrum here

These firms - including, it is understood, BT - believe that rural wireless broadband will only be commercially viable if 2GHz is used, rather than a higher frequency part of the spectrum. Companies will soon be able to bid for licences allowing...

Peter Cochrane's Uncommon Sense: You wear it well

Fortunately we have used less than 10 per cent of the frequency spectrum available. The key question is - how is the limited radio spectrum going to cope? Between 30 and 300GHz almost none of the spectrum is used as molecular resonances make it...

Peter Cochrane's Uncommon Sense: Mobile guesses

First, we have so far, only used up to 10 per cent of the frequency spectrum available. A key question: will the limited radio spectrum cope with all this? Every few hours each element can check to see if it is still optimised relative to the...

Grid computing reaches new prime

The prime number search, a conceptual cousin to the SETI@home quest to detect alien communications in radio telescope signals, is at one end of a spectrum of technology for pooling computing resources.

Ofcom auction: High-frequency spectrum to highest bidders

Telecoms regulator Ofcom is to auction four bands of high-frequency spectrum which could be used for wireless broadband services. Ofcom will conduct an online auction of individual lots of the spectrum on a "technology- and service-neutral basis".

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
