You can't get the staff

You can't get the staff

You just can't get the staff: that's the problem with mainframes. Anyone with a weather eye on what's happening in datacentres will know that the mainframe is far from dead -- in fact, it's undergoing a mini-revival, as enterprises re-centralise their infrastructures.

Apple nails the service providers

Apple nails the service providers

It may not surprise you to know that Apple plays hardball when it negotiates with service providers over the iPhone. It may surprise you to know that Apple doesn't negotiate at all, at least according to an informal discussion I recently had with a representative from a mobile comms provider.

Dedupe processing chews your CPU

Dedupe processing chews your CPU

There's just too much stuff out there, and it's filling storage devices as fast as they can be upgraded -- 50 percent data growth a year, I'm told, is par for the course. We 're talking about standard end-user data, what the storage industry refers to as unstructured data, as opposed to databases.

Living in the cloud

Living in the cloud

Over lunch the other day with VirtualSharp (of which more at a later date), I was asked what I saw as being the hot areas (as it were) for the datacentre.

Are you a cloudy sceptic?

Are you a cloudy sceptic?

Is the time for scepticism over cloud computing drawing to a close? As someone who rails against whatever is hailed as the latest and greatest, and refuses to believe uncritically in the wisdom of crowds, the hoopla around the cloud has oft given me pause for thought.

Is IBM's cunning mainframe weaving magic?

Is IBM's cunning mainframe weaving magic?

Mainframes have never gone away, despite what many in the PC business would like to think. And as servers start to look less and less like PCs and, as they consolidate in the datacentre using techniques such as virtualisation, increasingly like mainframes, you'll soon start asking why you should bother with servers at all?

Is good enough good enough?

I was browsing my bookshelves the other day when I came across a book that I acquired (and I think I reviewed while working on PCW) over 20 years ago, called 'LANs Explained'. It was released in 1988.

How low can a datacentre get?

How low can a datacentre get?

The datacentre is a hot area right now -- mainly because of cooling. The key here -- as you won't be surprised to learn -- is that cooling costs are rocketing so there's a case to be made for investing in smarter ways of cooling them.

It's summer: are your servers drowsy?

Have you ever heard of drowsy servers? Sadly, it's not about lounging on a hot summer's afternoon while drinking white wine and watching the garden grow, but servers that can throttle back on the basis of workload.
