2011 was a year where despite the economic constraints everything Big was
seemingly good: Big Data, Big Clouds, Big VMs, etc. Caught in the industry's
lust for this excess, 2011 was also the year I lost count of how many
overprovisioned resources to ‘Big' Production VMs I witnessed. More often
than not this was a typical reaction from System Admins trying to alleviate
their fears of potential performance problems to important VMs. It was the
year where I began to hear justifications such as "yes we are
overprovisioning our production VMs..but apart from the cost savings,
overallocating our available underlying resources to a VM isn't a bad thing,
in fact it allows it to be scalable". Despite this 2011 was also the year
where I lost count of the amount of times I had to point out that sometimes
overprovisioning a VM does lead to performance problems - specifically wh... (more)
Roll back several years and certain vendors had you believe that Fibre
Channel was dead and that the future would be iSCSI. A few years later and
certain vendors were then declaring that Fibre Channel was dead again and
that the future was FCoE. So while this article is not a iSCSI vs FC or FC vs
FCoE comparison list (there's plenty of good ones out there and both iSCSI or
FCoE each have immense merit), the point being made here is that Fibre
Channel unlike Elvis really is alive and well. Moreover Fibre Channel still
remains the protocol of choice for most mission-critical applic... (more)
Any new technology adoption happens because of one of the three reasons:
Capability: It allows us to do something which was not feasible earlier
Convenience: It simplifies Cost: It significantly reduces cost of doing
something
What is our expectation from cloud computing? As I had stated earlier, it is
all about cost saving … (1) through elastic capacity and (2) through
economy of scale. So, for any CIO who is interested in moving to cloud, it is
very important to understand what the cost elements are for different cloud
solutions. I am going to look at 3 platforms: Amazon EC2, G... (more)
If you are developer and would like to try out library that provides a set of
functions for emulating a file system and a system registry for an
application, ckeck out BoxedApp SDK.
It is a great way for creating virtual files, fake registry entries, keys and
value.
With BoxedApp SDK you have following features:
Create virtual files Create virtual registry keys
API for intercepting functions Embed DLL Embed ActiveX / OCX Launching a
virtual file-based process Using virtual file system by several processes
simultaneously
If you are wondering when to use this SDK see some examples ... (more)
Talk to the average Storage Engineer who manages the growth of your
datacenter’s modular system about Petaflops, Exabytes, Petabytes of
Archives or 1TB of sustained bandwidth and you’ll probably find them
scratching their heads in disbelief. This is the reality that does exist in
the world of super computing and what is sometimes referred to as Extreme
Storage. While some Storage Managers would feel they are suffering with their
exponential data growth and decreasing budgets, their problems can’t be
classified as ‘Extreme’ unless they’re dealing with ExaBytes (1018
bytes) of ... (more)
