Concept
Mission
To create systems redundancies which aim to
eliminate interruptions in service attributable to:
 Data center component failure
 Data center facility failure
 Communications link failure
 Building becomes temporarily or permanently
inaccessible
Kraft
Kennedy
& Lesser
Inc.
Assumptions
The plan directs investments toward protecting firm applications
deemed most critical.
Critical applications are defined as those which pose the most risk to
firm operations should they become unavailable for any period of time.
They are:






Messaging
Document Management and Document Processing
Time Entry
Litigation Systems
Contact Management
Conflicts
The remaining less critical applications will be restored as needed if an
outage is determined to be long-term.
Kraft

Capabilities as of 2000/1
Standard top tier law firm practices.
The firm’s data centers are protected by:




Fire control systems
Temperature control systems
Physical security systems
Uninterruptible power supplies
Hardware components are protected by:
 Duplicate power supplies
 Duplexed/RAID hard drives
 Redundant Internet access communications facilities
Firm data is protected by tape backup procedures and data is regularly moved
to off site storage.
No real time ability to utilize that data in case of systems failure.
Kraft
Kennedy
& Lesser

Options for increased
capabilities
 Establish disaster recovery hot-site.
 Establish primary data centers serving as “hotsites” for each other.
 Establish redundant off-site data centers.
Kraft

Disaster Recovery Hot-Site
Advantages:
 Protects multiple offices from disaster in any single location.
 Hot-site is easily scaled to backup addition applications or
locations.
 No reliance on communications for normal operations.
Disadvantages:
 Does not provide full systems recovery.
 Does not protect from component failure.
 Does not leverage economies of consolidation.
 Requires large distributed IT staff.
 Solution is disruptive to implement.
Kraft
Kennedy
& Lesser
Inc.
Internal Hot-Sites
Advantages:
 Allows for rapid recovery.
 Leverages existing firm locations.
 Reduces space required for some data centers.
 Reduces efforts for some systems upgrades.
Disadvantages:
 Need to acquire significant additional space in primary locations.
 Existing locations do not have ideal facilities.
 Does not fully leverage economies of consolidation.
 Requires distributed high level IT staff.
 Solution is most disruptive to implement.
 Solution is most time consuming to complete.
 Must invest in redundant communications links from small offices to
consolidated data centers.
Kraft
Kennedy
& Lesser
Inc.
Redundant Off-Site Data Centers
Advantages:
 Allows for rapid recovery.
 Reduces space required for in office data centers.
 Allows data centers to be located in less expensive locations.
 Allows data centers to be located in buildings with enhanced facilities.
 Increases in DR protection are realized during implementation process.
 Allows for IT staff consolidation.
 Allows for simplification of systems design.
 Dramatically reduces efforts for systems upgrades.
 Dramatically reduces time to support new locations.
 Requires smallest amount of hardware and software.
 Solution is least disruptive to implement.
Disadvantages:
 Must invest in redundant communications links from all offices to data
center locations.

Recommendation
Implement Redundant Off-Site Data Centers
 Provides most comprehensive and highest
levels of protection against data center and
building disasters.
 Option best meets defined mission.
 Utilizes financial industry best practices.

Strengths & Weaknesses of
Current System Architecture
Advantages:
 DMS and messaging are decentralized. Failure in one office does
not affect the rest of the Firm.
 DMS and messaging are not dramatically affected by local
communications link failure.
Disadvantages:
 Minimal system redundancy.
 Vulnerable to local system and power outages.
 Firm data is protected by tape backup only.
 No real time ability to utilize data in case of system failure.
 Maximum of days to weeks of downtime and 24 hours of data loss.
