IOPS is commonly recognized as a standard measurement of performance whether
to measure the Storage Array’s backend drives or the performance of the
SAN. In its most basic terms IOPS are the number of operations issued per
second, whether, read, writes or other and admins will typically use their
Storage Array tools or applications such as Iometer to monitor IOPS.
IOPS will vary on a number of factors that include a system’s balance of
read and write operations, whether the traffic is sequential, random or
mixed, the storage drivers the OS background operations or even the I/O Block
Block size is usually determined by the application with different
applications using different block sizes for various circumstances. So for
example Oracle will typically use block sizes of 2 KB or 4 KB for online
transaction processing and larger block sizes of 8 KB, 16 KB, or 32 K... (more)
Archie Hendryx looks at the benefits and challenges of managing multiple IT
components through a single support solution
Many public sector organisations are not changing their ICT legacy systems.
As a result, they face increasing number of inefficiencies and challenges.
These issues can nevertheless be overcome, and performance increased, by
managing these legacy systems within a converged infrastructural environment.
This approach can also reduce the risks associated with legacy systems, such
as security, missing functionality, increased complexity and operational
I was recently asked my opinion on what were the main considerations for
Cloud Computing with specific emphasis on Internal Clouds.
Eager to assist I quickly gave a rundown of issues which included SLAs,
distinguishing charge rates, security etc, etc.
Pleased with the response received our conversation then veered off into
another direction but then it struck me - I had just fallen victim to the
marketing jargon. Internal Cloud?
What on earth was he asking me and what on earth had I just answered with?
I thought back and reassessed my understanding of the Cloud to what I
2009 seems to have been the year of corporate marriages but whether they are
marriages made in heaven is yet to be seen. The ongoing saga between Oracle
and Sun and their child ZFS is already suffering from the clutches of the
scorned mistress ECC, while the Dell/ Perot and HP/3Com matches are still in
their honeymoon period. One partnership though which does look likely to
stand the test of time and causes the biggest threat to all others is that of
Cisco, EMC and their wonderkid Vmware.
The discussion on how in my opinion these three will monopolise the future of
ILM and cloud ... (more)
While personally, I believe the Sidekick disaster was just a stumbling block
in the embracing of cloud computing for many organizations, today’s news
that the newly formed alliance of SUN and Oracle was possibly to blame adds a
whole new dimension to the issue.
According to some reports the Sidekick service crash involved an Oracle RAC
database and Solaris and Linux servers. Currently unlike EMC who were quick
to retract the finger pointers, Oracle and Sun declined to respond to the
To put a picture on the background of this scenario one needs to firstly look
at the ... (more)
