You won't have read about this in many places but there's a humongous new enterprise-level switch in town.Alcatel-Lucent has just released news of the OmniSwitch 10K, a chassis-based 10 Gigabit Ethernet (10GigE) switch aimed at the datacentre.
What's going on in networking, operating systems, servers, storage and data centres?

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.
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.
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.
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. I responded, predictably enough perhaps, that I saw the intertwined issues of power, cooling and efficiency as the most important issues that datacentre designers and managers will be focusing on for the foreseeable future.
Mobility is where we're all going, say the sages, and evidence seems to bear them out. From the kids at home to workers in the office, laptops are ousting desktops in a whole host of situations.
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.
Have you ever wondered what IT security officers do on their days off? The answer seems to be that they're as security-conscious at home as they are at work, according to this article.
It started as a young bloke building PCs in his front room. Now Dell is starting to look like one of the world's technology powerhouses.
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?
A crowded train full of families on their way up to London might not, at first blush, be the natural place to think about security. But in many ways it's perfect.
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.
Recent weeks have seen a fascinating discussion emerging in the storage area of the LinkedIn business networking site on the merits of disk versus tape. Its the old story: tape is old but reliable and uses zero energy while it's storing archived data.
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.
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.
