IBM TotalStorageT Silo Compatible Tape Frame 3590 An IBM 3590 storage solution designed to provide leading-edge tape technology for StorageTek Silos attached to ESCON, FICON, SCSI, and Fibre Channel-connected servers Highlights
A StorageTek silo configuration with an IBM TotalStorage Silo Compatible Tape Drive Frame Overview The IBM TotalStorage Silo Compatible Tape Drive
Frame helps enable StorageTek ACS users to increase the value of
their current automation installation by enhancing it with 3590
technology. This leading-edge solution is designed to provide the
technology path and performance to help leverage current automation
investments while reducing the requirement for additional automation
hardware in addition to lowering environmental and maintenance costs
and reducing floor space requirements. Silo Compatible components The Silo Compatible solution consists of the following
components: Increased capacity 3590 Tape Drives attached to a StorageTek ACS can
use the 3590 Extended High Performance Tape Cartridge, which has
a native capacity of up to 20 GB on Model B1A Tape Drives and up
to 40 GB on Model E1A Tape Drives. With 3:1 LZ1 data compression,
capacities can reach up to 60 GB on Model B1A drives and up to 120
GB on Model E1A drives. IBM TotalStorage Enterprise Tape Controller 3590 Model A60 The IBM TotalStorage Enterprise Tape Controller
3590 Model A60 attaches 3590 Tape Drives to Enterprise System CONnection
(ESCON) and FIbre CONnection (FICON) channels on IBM S/390 enterprise
servers and IBM The 3590 Model A60 provides one to four dual-ported ESCON channel attachment features, enabling up to eight ESCON channel attachments. With native FICON support, up to two FICON features are supported on the A60 Controller providing attachment to one or two FICON channels. The FICON maximum channel link speed of 100 MB/sec full duplex (versus 17 MB/sec simplex for ESCON) can enhance tape performance. Both ESCON and FICON attachments are supported on the Model A60, enabling 3590 Tape Drives to be shared between ESCON and FICON servers. Each channel can have up to 64 logical channels, with multiple logical paths per MVST image. The 3590 A60 now supports high-speed location to relative file position. This new capability can significantly improve read performance for file-stacking applications that access by file number rather than block ID. The A60 can also offer significantly improved write performance for applications that stack multiple small files on a tape. The performance gain is achieved through the elimination of costly redundant, rewritten tape marks, and the associated backhitch. These new performance capabilities of the hardware can be exploited by OS/390® and z/OS® and are designed to be transparent to the user application.
3590 Tape Drives fully integrated in a StorageTek Silo Flexible configurations Up to four 3590 Model C12 frames with 3590 Tape
Drives can attach to every Library Storage Module (LSM) in an ACS.
A maximum of sixteen 3590 Tape Drives can reside in a StorageTek
LSM. 3590/ACS Silo communication To support seamless, reliable operation, each 3590
Tape Drive in a C12 frame communicates with the LSMs Library Control
Unit (LCU) using Storage Tek's library ports. In an ESCON/FICON
environment, 3590 Tape Drives running in 3490 E emulation mode are
identified to the StorageTek Host Software Component (HSC) as an
STK 36-track drive model. When drives are installed in native 3590
mode, they are identified as an STK model that can run as device
type 3590. This enables 3590 Tape Drives to be integrated into an
existing ACS environment typically without host software modifications. Investment protection 3590 Model B1A Tape Drives can be field-upgraded to the Model E1A, helping to protect existing investments in 3590 technology. Media investment is also preserved because the Model E1A drives can both read and write to the previous 3590 High Performance Cartridge Tape. Both Model B1A and Model E1A drives can double existing capacity when upgraded to the Extended Media Support feature enabling the use of 3590 Extended High Performance Cartridge Tape Coexistence capability 3590 Tape Drives can coexist with varying combinations
of StorageTek tape models, based on the level of HSC or ACSLS that
is being used.
3490E emulation 3590 Tape Drives attached through a Model A60 Controller can appear to the host operating system as native 3590 or 3490 E Tape Drives. Defining the 3590 in the ACS as a 3490 E offers flexibility for application set up and drive integration in the Silo environment. New 3590 A60 hardware enhancements improve tape cartridge capacity utilization. Now, applications operating in 3490 E emulation mode that write small blocks can exploit the capacity of the 3590 E model and extended length cartridge. This capacity enhancement can also be exploited by DFSMShsmT. Service IBM provides a comprehensive maintenance service program for StorageTek silos and drives in the United States and other selected countries. For the IBM TotalStorage Silo Compatible Tape Drive Frame, IBM has two service offerings. The first offering includes complete maintenance for both the Enterprise Tape System 3590 and the StorageTek Silo. The second provides service to the Enterprise Tape System 3590 only. 3590 media Media for 3590 Tape Drives can be ordered via 3590
Model C12 feature codes, via IBM 3599 models or from authorized
dealers. To order IBM media and supplies in the United States, call
toll-free 1-888-IBM-MEDIA (1-888-426-6334). Call Home function The IBM "Call Home" function automatically opens a service alert when a problem occurs with a 3590 A60 Controller. A service representative can be sent to the installation and status information can be transmitted to the IBM Support Center for evaluation. In addition, the Call Home function can send alerts to a pager service so that multiple people can be notified. Silo Compatible at a glance
