Game changer for customers needing active-active compute and storage configurations
Global-active device will allow customers to move to an active-active fully fault tolerant storage configuration‒ All that is required is global-active device, multipathing software, and
VSP G1000 systems, excluding the quorum.‒ Enterprise-class customers seeking the strictest IT availability
requirements will gain from global-active device when failure is not an option

Synchronous remote copy of a data volume
Active / Active configuration
Campus Distance configuration a host is connected to both storage systems
Metro Distance configuration a host has a primary path and a non-preferred path to insure the shortest path to the data is always used
What is Global Active Device
© Hitachi Data Systems Corporation 2014. All rights reserved.17
Host sees a single volume on a single storage system‒ Secondary storage system has a virtual storage machine (VSM) that
looks like the primary storage system
‒ The primary and secondary volumes are assigned the same virtual LDEV number in the VSM
‒ Pair volumes are seen by the host as a single volume on a single storage system
‒ Both volumes receive the same data from the host

Main DKC/Reserve DKC HA mirrored volumes for production servers Mirrored volumes accept Read/Write I/O on
both sides Requires 2 G1000 storage systems
Quorum DKC Quorum disk, determines HA owner node in
the case of a failure Any storage system can be used as long as it
is supported by UVM
Production Servers Clustered App/DBMS Active-Active processing with sharing the
same data
Global Active Device achieves concurrent references/updates of mirrored volumes, while keeping data consistency

Storage Management Server Clustered HCS server is running,
where the local HCS server enables HA management
In the case of local site failure, the remote HCS server takes over the HA management
HCS DB should be replicated with either TC or HA
Pair Management Servers Runs HDvM Agent/CCI HCS management requests to
configure/operate the HA mirrors via the command device
HCS offers efficient management of Global-Active Devices While providing central control of multiple DKCs

GAD Failure Cases
Failure Cases and Failback procedures‒ Single path Failure
‒ Primary Storage System Failure
‒ All Active path to P-Vol fail for a single host in the cluster
‒ Quorum Disk Failure
‒ Storage Replication link failure
‒ WAN Storage Connection Failure
‒ Primary Site Failure
‒ Secondary Site Failure
