The realities of server management - a conversation
Please go here
http://resources.zdnet.co.uk/articles/video/0,1000002009,39437728,00.htm
to check out the first (of 3) slices of our recent discussion here on what our summer server OS research has told us about the reality of the UK market.
I think the insights of the panel - respected analyst Katy Ring of The Bathwick Group, a Linux (Debion) and MSFT customer - are well worth hearing.
Did we get to any answers? Well, it'd be nice, we agreed, if we could get a cross-platform unified server management tool... that'd be nice, yes, along with World Peace and a pill that would take off 3 stone overnight. (That was my wish item after seeing meself on screen, not a serious point in the conversation.)
Will put up links to parts 2 and 3 as they come on stream.

UNIX is of course far more than just Linux
A couple of weeks back (28th May) I posted that I recommended an innediate trip to the Laughing Academy for anyone still doing work in a UNIX that was non-Linux.
I had in mind the proprietary OSes of course of the likes of IBM (AIX) and HP (HP-UX) - and I still doubt if anyone is starting fresh endeavours on those platforms, though of course maintenance/legacy work will continue for a good few years yet.
Problem with my analysis: I had of course forgotten that big non-Linux UNIX still very much alive. Step forward our friends at Sun Microsystems and Solaris.
It would be patently daft to prematurely bury Solaris and I stand corrected.
Where this leaves UNIX is still an interesting question, surely - Solaris vs Red Hat vs SuSE versus non-commercial distributions of Linux, it seems.

Cost and control key to server management for foreseeable
Took part in a fascinating debate the other day here at ZDNet.co.uk which we filmed and which will be on the site in the next few days.
This was again exploring issues thrown up by the research but that was just the starting point. This time the experts we had in to kck around the problems were an analyst and two users, one a confirmed Linux (Debion) man and the other primarily (but not exclusively) a Microsoft Server backer.
I don't want to blow the cool stuff in the video before it goes up, obviously, but if there was any one consistent theme it was this: Wish as we might for one meta (mega?) server control layer, the nature of this stuff (its complexity and legacy aspect) means server management will always be a central factor in any IT professional's life.
Sometimes, yes, we will have rock-solid server OSes at the foundation of the stack. BUT we will always have 'the stack' - as in, a web of complexity, made up of new, old, partner, and yes, broken environments to make work.
Wish it were different? Well, me too. But then I wish Portugal had won last night's Euro 2008 quarter final - I am out of the office sweeptsake now :-)

A new threat from the datacentre: you're making your staff deaf!
An interesting side effect of datacentre growth has come to my attention, as part of this month's intense look by ZDNet.co.uk into server use in the UK (based originally into our poll of the ZDNet UK community, but since bolstered by commentary and input from a range of sources from analysts to suppliers to end users): such growth can lead to health and safety violations.
We're talking risk of deafness.
The threat is the sheer noise building up in busy server rooms, as they crank up the volume to cope with all the heat they need to dissipate. Think about it: with their tiny processor fans, how hard do those little machines have to sweat to cope?
The law says the minimum above which danger to hearing can occur is 80 decibels on a daily/weekly exposure - that's about as loud a sound as loud singing from 3 feet away or a noisy car driving by as close as 25 feet from you.
I'd say in my experience we are easily meeting that level in busy server farms!
FYI, according to the government (http://www.hse.gov.uk/noise/), the latest iteration of legislation around noise hazards in the workplace specifically state, 'By law, as an employer, you must assess and identify measures to eliminate or reduce risks from exposure to noise so that you can protect the hearing of your employees'.
Another argument for consolidation/virtualisation/green IT, I'd say.

The research has been scrutinised by suppliers...
Go here to see a panel discussion on the findings of the server OS survey, where I spoke to representatives of Red Hat, VMware and Novell

(It's about a 40 minute conversation split into three chunks)
I also wrote this longer piece of editorial on the survey which goes into more depth on some of the findings
