7116 provides 33 TB SAS storage in a IBM TS7700 3956-XS9 Cache Drawer, providing 11 encryption-capable 3TB 7200 RPM SATA disk drive modules for a total of 33 TB of disk storage capacity for the IBM Mainframe System z platform. The TS7740 and TS7720 speed up tape backups and restores by using a tiered hierarchy of disk and tape to make more efficient use of tape drives for IBM Mainframe System z. The IBM TS7700 virtual tape library for the IBM z platform uses disk drives for cache to accelerate backup operations. The design is intended to protect IBM Mainframe System z data while having shorter backup windows, and ability to provide end-to-end encryption to protect data in motion, on cache hard drives and on tape.
The 7116 feature for the TS7720 3956-XS9 Cache Drawer and all IBM Mainframe System z and TS7700 upgrades, features and parts are IBM Certified, include warranty, can include 1 or 3 year IBM Maintenance Contract with purchase and may be quoted with financing options.
The 3956-XS9 provides approximately 24 TB of usable capacity for a TS7720. The TS7720 maximum supported usable capacity is approximately 240 TB, and maximum supported usable capacity of the TS7720 Encryption Capable Expansion Frame is approximately 384 TB. The TS7720 supports nine 3956-XS9 Cache Drawers in the F05 frame with a 7331. Each 3956-XS9 TS7720 Cache Drawer contains 11 DDMs, each have a raw capacity of 3 TB (2.73 TiB) or 24 TB (21.83 TiB) when used with RAID-6 formatting. The base TS7720 Cache can be configured to contain up to nine 3956-XS9 TS7720 Cache Drawers attached to one TS7720 Cache Controller. Fully configured, the base TS7720 Cache has a total usable capacity of 238.79 TB (217.18 TiB). A fully-configured base TS7720 Cache can be expanded by attaching to a TS7720 Storage Expansion Frame using FC 7332 TS7720 Encryption-capable expansion frame. The TS7720 Storage Expansion Frame adds one 3956-CS9 TS7720 Cache Controller, which can attach to a maximum of fifteen 3956-XS9TS7720 Cache Drawers providing 3 TB each.
A fully-configured base TS7720 Cache can be expanded by attaching to a TS7720 Storage Expansion Frame using 7332 TS7720 Encryption-capable expansion frame. The TS7720 Storage Expansion Frame adds one 3956-CS9 TS7720 Cache Controllers, which attaches to a maximum of 15 TS7720 Cache Drawers (3 TB 3956-XS9). Every TS7720 Cache Controller and its attached TS7720 Cache Drawers are referred to as "strings", with each TS7720 Cache Controller acting as the "head" of the string.
