TS7770 with 3956-CSB Cache Controller
The TS7700 Cache Controller consists of a redundant array of independent disks (RAID) controller and encryption-capable disk storage media, which act as cache storage for data.
The TS7700 Cache Controller contains 12
disk drive modules (DDMs).
Note: Total cache capacity that is shown reflects raw capacity and does
not directly correlate to usable capacity.

The CSB may be utilized for all models of TS7700 and is offered with 10TB NL-SAS 7.2k RPM drives.
The CSB and corresponding XSB drawers supports encryption abilities, as before, including internal key management and external key management.
Highlights of the CSB are:- 2U bays supporting 12 3.5” disks
- SAS drive technology utilizing SAS backbone between drawers o Supporting both SAS and NL-SAS disks, including SAS SSD
- Dual active 16 Gb FC connectivity to host
- Negligible performance impact for encryption.
- Internal key management
- External ISKLM/TKLM/GKLM support
- Thales CipherTrust Manager support for CSB
- TS7760 Cache Controller
- The TS7760 Cache Controller (3956-CSA) contains 12 DDMs, which each have a capacity of 4 TB (3.63 TiB) or 8 TB (7.27 TiB). You can mix 4 TB or 8 TB drives within a frame but you cannot mix them within a drawer or enclosure. The 3956-CSA and corresponding 3956-XSA drawers support all encryption abilities as the 3956-CS9 controllers, including cryptographical erase, internal key management, external key management, and retro-active enablement. The 3956-CSA cache controller and supported 3956-XSA expansion drawers support the ability of Dynamic Disk Pools (DDP). This virtual RAID6 technology can provide an RAID6 level of reliability while drastically cutting down the drive rebuild times after a drive failure.
