The best method of Storage virtualization has been one of the most debated
and argued issues within the industry. Nobody argues that while it is nothing
more than an abstraction between the storage device and its application, the
benefits that come with it such as consolidation, ease of management, online
migrations etc. make it a fundamental aspect of the constantly
non-heterogeneous emerging world of storage.
Of course virtualization is on everyone's lips with the advent of VMotion and
Vstorage offered by the Server-based storage virtualization solution of
VMware. Veritas Volume Manager and SUN's ZFS are others which come to mind
which have made virtualization an inbred of the Storage management arena.
But it was not so long ago back in the pre- VMAX days that most of the debate
revolved around whether virtualization should be via the SAN or via the

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
Mergers & Acquisitions on Ulitzer
With only the ‘you may now kiss the bride’ custom to follow, the
Oracle/Sun marriage (or dare I say Sun/Oracle) is now finally complete. After
months of legal wrangling which has caused nothing but embarrassment and
dwindled Sun’s stature within the market sphere, reports also came out that
half of Sun's 27,000 staff will be made redundant. Thus initial indications
are clear that Oracle, known for its past agnosticism to open source has an
eye for the merger being based on maximizing profit. In the meantime Sun’s
competitors are probably smiling... (more)
On a recent excursion to a tech event I had the pleasure of meeting a
well-known ‘VM Guru', (who shall remain nameless). Having read some of this
individual's material I was excited and intrigued to know his thoughts on how
he was tackling the Storage challenges related to VMware especially with
Fibre Channel SANs.
"Storage, that's nothing to do with me, I'm a VirtGuy", he proudly announced.
To which I retorted, "yes but if there are physical layer issues in your SAN
fabric, or poorly configured Storage etc. it will affect the performance of
your Virtual Machines and their applic... (more)
Generally IT folk, whether in Storage, Virtualization, Change Management or
Project Management love the use of acronyms and synonyms to express key
concepts amongst each other. What other industry would allow an individual to
spurt a line such as "Have SOX seen the BCP and CAB approval for our VDC's DR
SAN and will this then be added to the CMDB by CoB today?" without
immediately flinching or bringing in a logopaedics specialist for help. More
often than not, IT folk have also used these synonyms and acronyms as
smokescreens to prevent outsiders from realizing "well this IT stuff... (more)
