Hitachi Data Systems announced today the availability of Hitachi Data Instance Director (HDID) v5.5, which includes improvements in a
number of important areas that our customers have requested. The first area is replication management.
The snapshot, clone and remote replication technologies available with Hitachi Virtual Storage Platform (VSP) family storage systems
provide the basis for modern data protection capabilities, including the elimination downtime associated with backup and recovery: you no longer need backup windows, and recovery point objectives (RPO) and recovery time objectives (RTO) can be reduced to near zero.
However, these replication technologies are complex to set up correctly and manage as the environment changes. This release of HDID takes a huge step in eliminating that complexity. The ability to create new replication pairs was enabled in HDID v5.0 and that eliminated the need to manually create Hitachi Open Remote Copy Manager (HORCM) files and custom scripts. HDID can now:
- Adopt existing replication, enabling HDID to easily integrate into existing environments by adopting existing replication (global-active device, TrueCopy, Universal Replicator, and ShadowImage). Adopting existing Thin Image snapshot configurations, however, is not supported in this release.
- Discard replication, which removes the adopted replication from HDID management, while keeping the replication configuration in the array. This can be used in case an incorrect replication is adopted. It does not return the replication to its original state. It is therefore advisable to take a note of the resources prior to doing this to allow effective clean-up.
- Fully orchestrate global-active device (GAD), our active-active storage clustering over distance solution. HDID can now create
GAD replication operations with S-VOL creation and allocation, create synchronized GAD snapshots or clones, and enable both primary and secondary protection with a single policy.
- Support disaster recovery takeover and takeback to provide the ability to automate disaster recovery using a replication
destination. This operation swaps the flow of data between the volumes (the P-VOL becomes the S-VOL and vice versa). Possible use cases include maintenance operations, application failures, network connection failures, or primary storage system failures.
- Monitor and report on Universal Replicator asynchronous replication consistency time (C/T Delta) to provide an indication of Recovery Point Objective (RPO) compliance. If RPO policies are not being met, Hitachi Replication Manager (HRpM) can be used to troubleshoot the cause of performance bottlenecks.
- Monitor and report on the journal usage of Universal Replicator (UR) asynchronous replication to help avoid performance problems. This is important because if the journal becomes full, the replication switches to synchronous mode to avoid data loss, but this may seriously impact the performance of the primary array, especially when the replication is occurring over a long distance with high network latency.
HDID v5.5 also expands application-consistent Thin Image space-efficient snapshot and ShadowImage
full-copy clone support to include:
- Oracle point-in-time recovery, additional Oracle 12c capability support, and Oracle support on Solaris (SPARC) and
- Microsoft SQL Server AlwaysOn Availability Group protection, log truncation and SQL Server 2016 (compatibility mode).
- Microsoft Exchange 2016 (compatibility mode).
- Ability to select individual SQL Server and Exchange databases for protection.
Additionally, HDID can now co-exist in Hitachi Dynamic Link Provisioning (HDLM) environments and now supports Simple Network Monitoring Protocol (SNMP) alerting. Also, the promotional 2TB free HDID license bundled with new HDS storage purchases has been terminated. All licenses now start with the 10TB all-inclusive base license.
