Globalization (Business Expansion)
Improving Business Continuity and Disaster Recovery Processes
Provide near-instant recovery
Badly Behaved Applications on the WAN
Balance approach across CPU, memory, network and storage
Space, Power, and Cooling
Different desktop profile for different groups of users
The Network Must Truly Support the Business at the Speed of Business
Customer Challenges Infrastructure Challenges Disaster Recovery Challenges Virtualization has changed the way we build data centers
Cloud computing is changing how we think about local and remote data centers
Virtualization and cloud based services says that any workload can exist anywhere, at anytime, on demand, and move to any location without disruption
If it’s done the wrong way, the network will become dumb pipes
Virtualization collapsed the different components of compute, networking and storage into a blob where differences in each individual layer are diminished
Cloud computing drives vendors to work together with integrated “stacks” solutions that include server, storage, networking, and management software
The stacks are more about an operational model rather than speeds, feeds, dials and knobs.
In simple words, the stacks solutions change the way we think about “best of breed” vs “integrated system”
Data Center Architecture Data Center Network VMware View Solutions Data Center
Interconnect Environmental SOLUTIONS Space - Power - Cooling These words never used to matter when many of the network systems in use today were being designed 10-15 years ago
Thus low efficiency AC conversion, horizontal airflow, and over-investment ( low density and utilization)
We ran out of space in many data centers: so everyone in the vendor community built denser servers, storage, and switches. Enter the blade server for instance
We ran out of cooling: CRAC units became increasingly more common.
We ran out power : If you need more power, you may have to subsidize a new sub-station. In many cases it is cheaper to move to a new managed facility out-of-state and put a high performance multi-gigabit WAN connection to connect the Data Centers
Data Center Tiering Layout Computer Room Physical Layout SPACE POWER COOLING Logical Physical Floor Plan Cable Pathways Computer Room Physical Layout Cooling Requirement The Downside of Virtualization Data centers that were built up to 2005 were not designed for 10, 20, or even 30 kW per rack
Cooling systems are not capable of efficiently removing heat from a compact area
If all the racks were configured at 20 kW per rack, the average power/cooling could exceed 500 W/square foot
Even some recently built Tier IV data centers are still limited to 100 W to 150 W per square foot average
As a result many high-density projects have had to spread the servers across half empty racks in order to not overheat -- lowering the overall average power per square foot
The Downside of Virtualization Power Requirement By using high-density 1U servers and Blade Servers, a single rack can have more processing power than an entire midsize mainframe of 10 years ago
40 servers stacked in a standard rack can draw up to more than 20 kW requirement
Blade servers provide more space saving benefits, but demand higher power and cooling requirements. But require 6 kW to 8 kW each. With 4 Blade servers per rack, power required is 24 kW to 32 kW per rack
Virtualizing the environment will use less server power when executed properly using fewer servers. However, many existing power distribution systems cannot handle providing 20 kW to 30 kW per rack
Typical maximum power per rack today is 8 kW
