“IT Runs the Business – Downtime is Not an Option”“Need to Address Regulatory Requirements” “But How Do I Fund This?”
“It’s all About the Application Being Available to the Users…….I’ve Done the Business Impact Assessment – Now IT Needs to Meet The Business Needs”
•“As Long as My Servers Are Up I’m OK”
“Need to protect data in transit and at rest. Access control, segmentation, encryption, protection ”
“I Can’t Keep Up with The Amount of Storage that Needs to be Backed Up, Replicated and Archived ”
•“I Need to Provide Lots of Bandwidth Between Data Centers and Make Sure Users Can Get to the Apps ”

Recovery Time Objective (RTO)What’s the maximum tolerable outage? When must operations resume after a disaster?

SAN Extension in the Enterprise
● Enterprise customers need a range of SAN extension solutions:● DWDM for massive channel aggregation● SONET/SDH for high-performance long-haul applications● FCIP for asynchronous replication, remote backup● Use most cost-effective transport for each application● Lower-tier services complement higher-tier services
● Multiple tiers of service = multiple platforms + multiple vendors?
