HP StorageWorks B-Series Remote Replication Solution Best Practices Guide (5697-6731, June 2007)

storage administrator is unaware of the outage, unable to respond or not present - because Cluster
Extension EVA™ requires no server reboots or LUN presentation/mapping changes during failover.
HP StorageWorks Cluster Extension EVA™ software is an integrated solution that provides protection
against system downtime with automatic failover of application services and read/write enabling of
remotely mirrored mid-range storage over metropolitan distances. Cluster Extension EVA ™adapts in real
time, to real life situations, providing protection via rapid site recovery. Cluster Extension EVA ™delivers
true hands-free failover/failback decision making - in the event the human storage administrator is
unaware of the outage, unable to respond or not present - because Cluster Extension EVA requires no
server reboots or LUN presentation/mapping changes d uring failover.
Cluster Extension EVA integration pr ovides effi ciency that preserves operations and delivers investment
protection as it monitors and recovers disk pair synchronization on an application level and offl oads data
replication task s from the host. Cluster Extension EVA supports the entire EVA family of arrays at either
the primary or secondar y site. Implementation of a Cluster Extension EVA solution assures the highest
standards in data integrity by m aximizing the advantages of its integration with Continuous Access EVA
Software, a nd with HP Ser viceguard for Linux in Red Hat and SuSe Linux environments and Microsoft
Cluster Service in Windows 2003 environments .

HP Metrocluster/HP Continentalclusters
HP Metrocluster and HP Continentalclusters are disaster-tolerant solutions for the H P-UX 11i environment.
Both are b
uilt on HP’s foundation clustering software, HP Serviceguard, providing the highest level of
availab
ility and business continuity for enterprise data centers. Both are integrated with Continuous
Access E
VA. HP M etrocluster is a business continuity solution with automatic site failover for up to 16 HP
Integrity or HP 9000 servers connected to array-based storage. It provides automatic and bi-directional
failover of business-critical da ta and applications located at data centers up to 300km apart, so both
data centers can be active, protected, and capable of handling application failover for each other. HP
Continentalclusters is HP’s disaster-tolerant solution for unlimited distances. Since there are no distance
limit
ations on how far apart the data centers can be located, Continentalclusters provides flexibility for
customers in where to locate their c omputing resources. It provides both manual and bi-directional failover
of business-critical data and applications over unlimited distance.
