The grid communication feature is designed to help keep data available, even if one of the remote sites experiences an outage; up to eight TS7700 systems can be configured to participate in a grid environment. This function helps maintain availability during planned maintenance, service or system upgrades, or unexpected outages and helps avoid the physical transportation of tape cartridges in the event of a disaster.
Advanced policy management
Enable cache management for volume retention and deletion with advanced policy management. Volume pooling allows grouping of logical volumes on physically separate cartridges or cartridge pools. Copy export allows sets of logical volumes to be written to physical tape for movement to remote sites. Logical write-once-read-many (WORM) can protect volumes from deletion. Cross-site replication creates a copy of a logical volume at different sites.
Disk and tape drive encryption
Help secure sensitive at-rest data with support for both disk and tape drive-based encryption.
Copy export acceleration
Improve the speed of large copy export operations and reduce the number of physical volumes that contain a copy of the database used for recovery.
Synchronous mode copy
Leverage true synchronous copy through real-time duplexing (simultaneous local mount and remote mount) and copy consistency at two locations up to any implicit or explicit sync point providing a zero recovery point objective.
IBM FlashCopy support for disaster-recovery testing
Perform disaster-recovery tests without interfering with production runs.
Remote-mount IP link failover
Improve remote read/write operations by utilizing alternate links in the event of path failure. If a failure occurs, the failover path searches another IP link to continue the job, without stopping or impacting the host or customer.
Enhanced compression options available
In addition to the standard compression built into the FICON adapters used by TS7700, two enhanced compression options are available to balance performance requirements with storage requirements: LZ4 compression and ZSTD compression algorithms. All clusters in a grid must be running R4.1.2 machine code, or higher, before either enhanced compression option may be selected.
See Hardware and Technical Specifications;
- More than 2.4 PB of user data capacity, before compression
- More than 13 PB capacity after compression (depending on data compressibility characteristics)
