There is praise here for using Linux in the datacentre and its use is continuing to grow. However, there is criticism with regard to high availability – even though the linux kernel is “pretty solid”, it is quite clear that setting up high availability is a pain in the proverbial. So instead of all that [...]

Here’s an interesting article from the Aberdeen Group about protecting virtualised environments. Some sound advice here about tiering your applications to understand whether they should be deemed normal, highly available or critical. This is especially true if you are virtualising them – and there is a note to say that over 50% of applications these [...]

When is the Cloud Viable?
A few objections constantly rear their ugly heads when clients consider cloud computing for their business critical applications. A couple of them are mentioned in this article. I would also argue that application latency is a show-stopper, but for now let’s park latency and security. That leaves us with availability. Most cloud offerings utilise tried and [...]

Here’s a good concise article (you may have to create an account to get to it) from InformationWeek about the “Road to High Availability” for SMBs. There are a few nuggets in there comparing Fibre Channel storage throughput with iSCSI. The article unfolds as it explores the complexities of HA (especially as you start using clustering) [...]

So IT complexity is on the rise is it, even with virtualisation? Is it really a surprise? Not when you consider that the majority of systems deployed rely on high availability clustering of some description – these are the systems that deploy failure/restart technology – generally they work but they sure are complex to administer [...]

HA for MS SQL
A succinct overview here of the High Availability options for Microsoft SQL server. It’s not very long but if you are really short of time then skip to the last paragraph. It endorses something that I have mentioned several times – fault tolerant technology. It’s really easy to setup and combines well with SQL mirroring [...]

I like the concept of belt and braces to stop the network falling down and the clear advice dictates that network redundancy requires two of everything. If you have the funds, then go for 4 of everything. When I read this I think of the compute node and ask what is a similar architecture? Fault [...]

Now I do like this article – fault tolerant technology available to the masses and financially viable. Not only should this type of technology provide simply fantastic uptime, they do so in a way that is very easy to manage. IT shops these days seem to be vastly over complex, no wonder then, that when [...]

Just been reading through this one and the dichotomy of automation vs. human control in situations where failures occur. I find it quite hilarious that the Disaster Tolerant Solutions Team remains focussed on very quick recovery and minimal business downtime. It’s not very tolerant then is it? In fact it’s not tolerant at all – [...]
