5 VIRTUAL DATA STORAGE TIPS
5 Virtual Data Storage Tips
If you’ve decided to move over to virtual storage, you’ll be likely
looking forward to a future of flexible storage using existing resources rather
than the upheaval of periodic hardware upgrades to keep pace.
While virtualized storage can offer much by way of flexibility, using
existing resources efficiently, saving costs and reducing your carbon footprint
it pays to think ahead and adhere to some basic procedures.
Plan
carefully
When moving over to virtualized storage, consider carefully the
software you’ll invest. Not only should it be able to meet current and future
requirements, you need to retain fluidity and that means avoiding vendor
lock-in.
Lock-in is where you find yourself having to buy a piece of hardware or
a software package from a specific manufacturer due to compatibility
considerations. It’s very important to opt for maximum compatibility and
‘hardware agnostic’ software so as to be able to make the most of your existing
resources.
It’s a basic principle amongst users of more modest software such as creative professionals who
often mix and match packages they like to use and that work well together, so
it certainly matters when planning a whole virtual infrastructure.
For example, if you go for hypervisor software from industry leaders
VMware with vSphere or Microsoft with Hyper-V, then you’ll require a virtual
SAN (Storage Area Network) that is compatible with them and can work perfectly
well with your existing commodity servers.
A package such as SvSAN from StorMagic meets the aforementioned criteria, so would
enable you to use your existing hardware and use an industry-leading hypervisor
with no threat of ‘lock-in’.
This also ties in with making things as seamless as possible when it
comes to integrating virtual storage into your setup. Existing resources are
retained and used as far as possible rather than a wholesale and expensive
upheaval.
Taking
your time
Do your homework in evaluating the virtualized storage solution that is
best for you. Ideally, look for a SAN vendor who will allow you to evaluate the
package for a period of time on a ‘test drive’ basis as the vendor mentioned
above offers.
Getting it right first time is imperative as the upheaval and expense
of changing courses later is clearly best avoided, so establish properly that
it meets your requirements.
The
learning curve
While you may already have experienced virtualization of your servers,
there’s still a learning curve when changing to virtualized storage. This is
where a vendor offering a ‘test drive’ of the software comes in very useful,
and even better if they’ll offer some support while you’re evaluating their
solution.
Disaster
recovery
While it’s heavily trumpeted that virtual storage set ups can adapt and
recover quickly from outages and other problems, it’s still important to be
totally familiar with how back ups and data recovery is achieved and how
quickly.
Support
levels
You’ll require good levels of support – and especially support that is
tailored to your requirements. It may be that you need more ‘hand holding’ in
the earlier stages, but look for a vendor who provides various levels of
support so you can choose the most appropriate.

ReplyDeleteWow, cool post. I'd like to write like this too - taking time and real hard work to make a great article... but I put things off too much and never seem to get started. Thanks though. Meridian Norstar
ReplyDeleteI have bookmarked your blog, the articles are way better than other similar blogs.. thanks for a great blog! check this
ReplyDeleteIt is worth focusing on that high access rate because of organization nonattendance, ability of storage limit expansion, information security and adaptation to non-critical failure are some of benefits of DAS. cheap hosting plans
