Site Failure‒ Catastrophic events like an

airplane taking down a datacenter & recovery issues

Business Challenge‒ Non-Stop Operation‒ Reaching zero RPO & RTO

Limited Failure Scenarios Gaining Connectivity from

Surviving Cluster

Customer Challenges

BUSINESS CONTINUITY


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


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

What is Global Active Device (cont.)


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

Global-Active Device Implementation Service


Implementation based on global-active device configuration:‒ Consulting service to arrive at optimum solution design

‒ Integrate global-active device configuration into customer’s environment and validate the system recovery

‒ Configure global-active device, zoning for global-active device cluster, multipathing software, and production pairs

‒ Create design documentation, perform on a test server and demonstrate recovering from various paths and quorum array failures

‒ Provide best practices on platform to limited staff, demonstrate features, functionality, and knowledge transfer

‒ Provide project management and technical oversight
