The TS1120-C06 can attach up to sixteen TS1130, TS1120, or 3592-J1A tape drives in a TS3500 library. For this attachment, there must be at least one FC switch per tape controller in a 3953 Model F05 Frame to route data between the controller and its associated tape drives. For reliability, two FC switches can be associated with one controller. The tape drives connected to a particular controller do not need to reside in the same frame. They can be spread across multiple frames in the IBM TS3500 Tape Library frames, as shown in Figure 4-7 on page 99. In this picture, one IBM TS1120-C06 Tape Controller has 16 tape drives attached: four tape drives in each of four separate frames. Another controller also has 16 drives attached, 12 of which reside in one frame and four in another frame.

The TS1120-C06 supports an intermix of 3592-J1A and 3592-E05; however, this intermix results in the 3592-E05 running in J1A emulation mode at J1A capacity and performance ratings.
4.2.4 Installation with an IBM TS3400 Tape Library
The TS1120 controller supports attachment of up to seven TS3400 libraries. Because each TS3400 can house up to two TS1130 or TS1120 drives, you can attach a maximum of fourteen drives installed in TS3400 libraries to one IBM TS1120 Model C06 Tape Controller. If an IBM TS1120 Tape Controller attaches to drives in a TS3400, all other drives attached to this controller also must reside in TS3400s.
Both the controller and the libraries need to be rack-installed. The TS3400 Tape Library does not support 3592-J1A drives.
Figure 4-8 on page 100 shows the maximum configuration of TS3400 tape libraries attached to an IBM TS1120 Tape Controller.

4.2.5 Installation with an IBM 3494 Tape Library
When using a C06 controller with an IBM 3494 Tape Library, the controller resides in a 3952 Tape Frame that is detached from the library.
There are two versions of the 3952 Tape Frame for the TS1120 Model C06: the 3494 attachment frame and the silo-attached frame. A maximum of three IBM TS1120 Model C06 tape controllers can be installed in the frame, as detailed in Table 4-3.
Table 4-3 TS1120 tape controllers in 3952 tape frames
The TS11200 Model C06 connects to the library through a 3494 D24 or 3494 D22 frame. The 3494 D24 frame or 3494 D22 frame contains the FC switches that the controller uses to communicate with the TS1130, TS1120, or 3592-J1A drives, the Ethernet router through which the controller communicates with the Library Manager, and up to 12 IBM TS1130, TS1120, or 3592-J1A tape drives. You can connect additional drives, up to a total of 16 per TS1120 controller, in an adjacent 3494 D22 frame or 3494 L22 frame.
Table 4-4 on page 101 lists the frame capacities for drives and controllers.

4.2.6 IBM TotalStorage 3592 Model J70 Tape Controller
The Model J70 controller is the predecessor of the TS1120 Model C06. It has been withdrawn from marketing, but existing installations can upgrade the microcode level of the J70 to support tape data encryption when encryption-enabled TS1120 tape drives are attached. See Figure 4-9.
The 3592 Model J70 controller supports TS1130, TS1120, 3592-J1A, and 3590 drives in a 3494 Tape Library and TS1130, TS1120, and 3592-J1A drives in a TS3500 library.
To use tape encryption, all tape drives behind the J70 must be TS1130 Model E06, TS1130 Model EU6, or TS1120 Model E05 drives, and in the system-managed (SMStape)
environment, intermixing encryption-enabled and non-encryption-enabled TS1120 Model E05 drives is not supported behind the same tape controller.

Frame Number of drives and tape controllers 3494 Model L22 Up to four 3592 tape drives and no controller
Note:
If a Model L22 frame is installed with the adjacent frame feature code (FC) 4065, FC4075, FC4085, or FC4086, up to four 3592 or TS1120 drives are supported in the L22 frame.
3494 Model D22 Up to twelve 3592 tape drives and no controller Note:
If a Model D22 frame is installed with the adjacent frame feature FC4065, FC4075, FC4085, or FC4086, the maximum number of attached 3592 drives is eight.
3494 Model D24 Up to eight 3592 tape drives and one 3592 Model J70 or 3590 Model A60 controller
4.3 IBM Virtualization Engine TS7700
The IBM System Storage Virtualization Engine TS7700 is a member of the IBM TS7000 Virtualization Family. It represents the fourth generation of IBM Tape Virtualization for mainframe systems and replaced the highly successful IBM TotalStorage Virtual Tape Server (VTS).
The TS7700 Virtualization Engine is designed to provide improved performance and capacity to help lower the total cost of ownership for tape processing. It introduces a new modular, scalable, high-performing architecture for mainframe tape virtualization. It integrates the advanced performance, capacity, and data integrity design of the IBM TS1120 and IBM TS1130 tape drives, with high-performance disk and a new advanced IBM System p server to form a storage hierarchy managed by robust storage management firmware with extensive self-management capabilities.
The two types of TS7700 at the time of this publication’s development are the TS7720 and the TS7740. The TS7720 is a disk-only virtual tape system with up to 70 TB of disk cache.
Because it does not attach to physical tape, it does not take advantage of tape encryption.
The TS7740 has up to 14 TB of disk cache and attaches to both IBM TS1120 or TS1130 tape drives.
The TS7700 Virtualization Engine integrates the following components into the virtual tape solution:
One IBM Virtualization Engine TS7740 Server Model V06
One IBM Virtualization Engine TS7740 Cache Controller Model CC6
Up to three IBM Virtualization Engine TS7740 cache drawers Model CX6
Figure 4-10 shows the IBM Virtualization Engine TS7700 and a schematic layout of its components.
Figure 4-10 IBM Virtualization Engine TS7700
TS7740 Cache Controller
Chapter 4. IBM System Storage tape automation for encryption 103 The TS7700 Virtualization Engine attaches to System z hosts through FICON connections, either directly or through FICON directors. It supports back-end drives in a TS3500 or 3494 tape library. When the TS7700 attaches to a TS3500 library, an external library manager is no longer required, as of licensed internal code 8.5.0.xx.
TS7700 characteristics
The TS7700 offers a new standards-based management interface and enhanced statistical reporting, compared to the VTS.
We summarize the important characteristics of theTS7700:
The TS7700 Virtualization Engine utilizes outboard policy management to manage physical volume pools, cache management to control selective dual copy, dual copy across a grid network, and copy mode control.
The TS7740 Server provides host connections of up to four FICON channels and connections to the tape library and tape drives for back-end tape processing.
A TS7700 with grid enablement features can be interconnected with one or two other TS7700s (TS7720 or TS7740) to provide peer-to-peer copy capability between virtualization engines for tape using IP network connections.
The TS7740 Cache, comprised of the TS7740 Model CC6 and the TS7740 Model CX6, provides from 1 TB to 14 TB of uncompressed tape volume cache (TVC) capacity.
Each TS7700 supports up to a maximum of 256 3490E virtual tape drives and up to 1,000,000 logical volumes, each with a maximum capacity of 1.2 GB to 12 GB (assuming 3:1 compression and using the 400 to 4000 MB volume sizes).
The TS7700 offers a new standards-based Management Interface (MI) and enhanced statistical reporting, compared to the VTS.
On demand features for cache capacity and performance allow for a lower cost entry configuration with the option to grow with minimal effect on operations.
The copy export function allows for export of secondary copies of volumes for disaster recovery purposes. The export operates on physical cartridge pools. The primary copy of exported volumes stays resident in the TS7700.
The TS7700 supports the TS3500 and the 3494 tape libraries. When it attaches to a TS3500 tape library, it requires an external Library Manager.
You can attach from four to sixteen TS1130, TS1120, or 3592-J1A tape drives to a TS7700. The drives can reside either in a TS3500 or a 3494 tape library. The TS7700 also supports a mix of TS1130 and TS1120 or TS1120 and 3592-J1A drives. In a mixed TS1120 and 3592-J1A configuration, the TS1120 drives run in J1A emulation mode.
TS1120 drives running in J1A emulation mode do not support encryption.
The TS7700 supports System-Managed Encryption. To utilize the encryption capability of TS1120 and TS1130 drives, all drives attached to the TS7700 must be TS1130 or encryption-enabled TS1120 drives.
The following operating systems support attachment of the TS7700 Virtualization Engine:
IBM z/OS V1.7 or later
IBM z/VM V5.1 or later
IBM z/VSE V3.1.2 or later
IBM z/TPF 1.1 or later
IBM TPF 4.1 or later
Earlier releases might support the basic functionality of the TS7700 Virtualization Engine.
