iNSP allows you to migrate data with no disruption to applications and hosts. You are
also able to increase storage utilization, as well as enable tiering and cross-tier copy services.
iNSP abstracts the SAN data path. This eliminates application downtime that normally
occurs with data migrations and device reconfigurations. iNSP software supports Cisco
MDS 9000 SAN switches, along with storage vendors such as 3PAR, HDS, IBM, and Sun.

Both server and storage virtualization can accomplish some important things for your
organization. First, there’s the obvious honey we’re trying to sell here: You become a more
green organization. By consuming less power, you’re generating less CO . By having less
2
equipment, less needs to be discarded at end-of-life.
However, there are also overall organizational benefits, such as the ability to access
applications from any branch office (or anywhere in the world, for that matter). Also,
adding more storage to your SAN can be as easy as slapping on a new hard drive and
letting your virtualization system use it as necessary.

Savings
So how much can you save by virtualizing your servers and storage? Let’s consider the
fictional software giant CompuGlobalMegaWare, which has decided to make the switch and
is going to virtualize and consolidate its servers and storage. It will be reducing the amount
of physical servers it has from 1000 down to 72—a 14:1 reduction.
The company is also going to reduce its 1000TB of storage spread across 13,700 hard
drives down to 1050 drives, or a 13:1 reduction. Let’s take a closer look.

Server Savings
In terms of storage, an average, run-of-the-mill server will cost US$9052 per year in costs.
Those costs include:
• US$4000 for purchase, support, and maintenance costs. This amount is amortized
over 3 years.
• US$1100 for storage and networking costs.
• US$333 for server provisioning and life cycle replacement costs, which consume
20 hours per server. That also assumes a 10 percent server growth. If your environment
is growing especially fast, expect this amount to be higher.
• US$2720 in ongoing administration.
• US$589 in power and cooling costs.
• US$310 for datacenter space costs.
In the CompuGlobalMegaWare example, reducing its physical servers from 1000 to 72
has the same carbon impact as removing 1124 cars from the roads.
