Disaster Recovery
»Disaster defined● An adverse, unfortunate and unforeseen event!● Being down● Being unable to service/support customers
»What is the largest enemy in a disaster?● Having an untested plan● Time!
4
Types of Disasters
»Natural (fire, flood, wind, earthquake, etc.)
»Malicious intent (virus, burglary, vandalism, etc.)
»Localized outages: ● Hardware ● Power● Telecom ● Software● Data Corruption
5
»Customers?
»Staff?
»The Business could be at risk!
»Disaster Examples● How many businesses never reopened after Katrina?
› Over 80% of companies affected went out of business within 18 months as a consequence

Who is Impacted?
6
Top Disaster Recovery Concerns
»Planning for the disaster»Resources to build and test BCP and DR plans»Communication of the plan» Inherent infrastructure problems»Backup challenges»Archival strategies»Replication strategies
7
What Should we do?
» Conduct a Business Impact Analysis (BIA)
» Create a Business Continuity Planning Office (BCPO)
» Establish Incident Management team (IMT)
» Establish a Life Safety – Emergency Response Team (ERT)
» Define DR plan owner● Define DR strategy

Disaster Recovery
»Where should we recover?● Cold site● Hot site● Production site and Dev/QA site
»When should we test?● Should test as often as possible (at least twice per year)● Involve business in testing● Increase complexity of each test
11
Why Should we worry
»Risk + Probability of failure● Local failure (fault tolerance). Most likely scenario.
› Disk › HBA› SAN Switch› SAN › Core Switch
● Proximity - location increases risk of incident› Highway › Airport (Memphis)› Water
12
DR Requirements
Match your internal fault tolerance and DR capabilities to:● The overall availability requirements of your company
› Do you need 99.999s?
● Recovery Time Objective (RTO) › Determined via BIA› Base your plan on lowest RTO
● Data loss tolerance - RPO › Determined via BIA› Base your plan on lowest RPO
13
Examples
»RTO = 4 hrs, RPO = 0, Availability = 99.999● All local infrastructure fault tolerant● Critical applications are clustered● Synchronous replication to hot site● Tape backup plan for recovery; tapes sent off-site every day
»RTO = 72 hrs, RPO = 24 hours, Availability = 99.5● SAN fault tolerant; core fault tolerant● Little to no clustering● Tape backup plan for recovery at a cold site; tapes sent off-site
every day
14
How will we keep our costs down?
»Virtualize ● Virtualization greatly simplifies DR● Virtualization reduces the cost of DR
»Reducing Backup Pain● De-duplication
› 20x data reduction› Extend disk backup
● Backup to disk (VTL)› Eliminate tapes in remote sites› Enable fast backup AND recovery› Use tapes for long-term archival only
15
How will we keep our costs down?
» Improving efficiency of SAN● Document Management Policy/Practice● Archiving (based on policy)
› Save $1000s on tapes while still protecting your data› Archiving will allow you to quickly restore business critical data › By using a tiered storage solution, you will have already
separated your business critical data from the rest› Improve TCO of SAN
»Use DR site for Dev/QA● Production replicates real time to DR site● Dev/QA replicates at a reduced interval back to SAN at
production site
16
Archiving
»Store more intelligently● Classify and tier
● Archive inactive data
● Eliminate redundant data
● Streamline backups
● Utilize snaps for incr. changes
● Virtualize servers

Archiving
» iSCSI● Least expensive connectivity
● Easy to replicate
● Pay as you grow technology
● Fast deployment

In the Face of a Disaster – Case #1
»What if everything is lost?»CDW’s Enterprise Configuration Center can be
your DR Site» In your time of need, you HAVE to have fast
response»Detroit-area customer
● Fire on Friday● Weekend re-build and re-image● Delivery
19
In the Face of a Disaster – Case #1
»CDW drop-shipped● Imaged desktops and
notebooks● Fully-configured
›Routers›Switches›Firewalls
● Wireless APs● Installed server racks
20
In the Face of a Disaster – Case #2
»What’s your backup plan?
»Environmental consulting firm● 10-ft. under water● Had developed plan with CDW
21
In the Face of a Disaster – Case #2
»BC/DR Plan● Hot site in Mississippi
› Relocation within 48 hours
● Asynchronous replication – SAN
● MPLS (IP-VPN)› Meshed environment
