Ensure IT Resilience
Creating an IT
Infrastructure for Business Continuity
Business
continuity is an issue that no organization can afford to
ignore. In fact, according to The Definitive Handbook for
Business Management, between 60 and 90 percent of companies
without a proactive disaster plan find themselves out of
business within 24 months of experiencing a major disaster.
Increasingly,
IT power and cooling are becoming more important as factors
in ensuring business continuity. These 10 steps provide a
good start for ensuring the integrity and availability of
your IT systems.
1. Assess
your situation.
Review existing power and cooling systems to identify
threats and vulnerabilities to business continuity.
2. Ensure
the physical security of your equipment
While large data centers often have strict access policies
and procedures, smaller locations or more remote locations
may not. It’s important to use racks that come with key or
card swipe locks and contact closures that protect against
unauthorized access. These locks and closures can be
connected to your network so you can easily provide
authorizations and monitor access. Within the rack, smart
PDUs enable control of individual receptacles. This prevents
unauthorized equipment additions that can overload circuits
and create a power outage.
3. Keep your
cool
High heat can reduce the performance of equipment. IT
equipment often requires 24x7 dedicated cooling, precise
temperature, humidity and air filtration control and more
efficient cooling provided only by precision cooling.
Typically, racks with 1kW to 3kW need dedicated cooling,
either through single cabinets with integrated cooling or
through room level cooling.
4. Eliminate
hot spots
Many data center now have high density servers. These can
create hot spots, causing equipment degradation and under
utilization of rack space. At 5kW and above, high-density
cooling often is required. You can resolve hot spots in
single racks with cabinets featuring integrated high density
cooling or in multiple racks by using high density
supplemental cooling in areas already served by room level
cooling.
5. Ensure
power quality
The most commonly used UPSs are line-interactive and do not
condition certain power problems such as frequency
variations and distortions until they go to battery. They
may pass utility power irregularities to the protected
equipment, resulting in the power being dropped. You can
mitigate this risk by using online UPSs, which fully
condition utility power before passing it to the protected
equipment.
6. Get the
UPS capacity you need
Insufficient runtime is the second most common cause of UPS
failure. Ensure that UPS sizing and backup are adequate for
your current environment and for future growth. Calculate
UPS size based on the full load of protected equipment – not
on “nominal loads” which are estimates of average loads and
could result in undersizing UPS capacity.
7. Increase
UPS reliability
Commonly used line-interactive UPSs will drop power if a
component fails. Online UPSs are twice as reliable, as
measured in MTBF. That’s because they has an internal bypass
that allows power to continue to the protected equipment in
the event of a UPS component failure. If total room power
load exceeds 15kW, it may be time to replace multiple rack
UPS systems with a room level system, which reduces the
potential points of failure created by the multiple UPS
systems.
8. Add
redundancy
Dual corded network equipment is designed for redundancy –
two PDUs, two UPSs, two power circuits – to protect
availability in case a single component in the power chain
fails. Redundancy down to the dual corded load, not just the
UPS, is required to maintain highest levels of availability
for critical loads.
9. Ensure
visibility and proactive monitoring
The power and cooling equipment your IT systems depend on
can be configured with Webcards that enable SNMP monitoring
of the IT infrastructure over the existing network. If
monitoring of critical systems is too time consuming,
consider outsourcing remote monitoring. Environmental
conditions – temperature, humidity and water leakage – also
must be monitored.
10. Have a
Strategy for Service
Extending the useful service life of the power and cooling
equipment through proper maintenance, predictive monitoring,
and keeping the equipment up to date increases equipment
lifespan and maximizes performance. Be sure to use
factory-certified service technicians who can work with your
local solutions provider to provide rapid response and
continuous maintenance.
