Uempty 1.1. R11A microcode enhancements

TS3500 R11A (Bxxx code) features and functions

The R11A (Bxxx) version of 3584 microcode, includes the following enhancements along with various fixes.

LTFS

IBM Linear Tape File System (LTFS) is the first file system to set a new standard for ease of use and portability for open systems tape storage. With LTFS, accessing data stored on an IBM tape cartridge became as easy and intuitive as using a USB Flash drive. With LTFS and the operating systems graphical file manager, reading data on a tape cartridge is as easy as dragging and dropping. Users can run any application designed for disk filesagainst tape data without concern for the fact that the data is physicallystored on tape. LTFS will be covered later in this topic.

Advanced Library Management System (ALMS) new functions

Two new functions that were added to ALMS are a modified library error log view that shows multiple entries instead of having to page through the log entries one at a time. The other ALMS new function is for auto eject of expired cleaning cartridges which will automatically eject a cleaning cartridge when it reaches the end of its clean cycles. Both of these new functions will be covered in this topic.

TS1140 (3592-E07)

Library Models L23 and D23 now integrate and support the IBM System Storage TS1140 Tape Drive Model E07 with its enhanced native data rate of up to 250 MB/sec and 4 TB native 3592 format advanced data cartridge physical capacity. Existing TS3500 Tape Libraries Models L22 and D22 also support the new TS1140 Tape Drive. An overview of the 3592-E07 will be presented later in this topic.

Support for 8GB FC switch

New 8GB FC switches to support the TS7740 Virtualization Engine using 3592-E07 backend tape drives will be covered in more detail in this topic.

Self-Study Booklet



Support for legacy x22 frame models

Continued support for x22 3584 library frames that have Enhanced node cards installed.

3584-SC1 Shuttle Complex

The new 3584-SC1 shuttle enables scalability of over 300,000 cartridges (or over 900 PB of uncompressed TS1140 data) in a single library image by supporting transport of cartridges from one 3584 library string to another 3584 library string. Application software supporting this new capability can move tape cartridges directly from its home logical library to the destination logical library. Shuttle connections will span High Density TS3500 S24 or S54 frames from different TS3500 library strings. The 3584-SC1 shuttle supports new and existing TS3500 tape library installations. The 3584-SC1 will be covered in topic 2.

LTFS

Since the invention of disk storage, tape has been viewed as complex and difficult to use since, until now, it has required tape device specific software to read, write and manage data stored on tape cartridges in tape libraries. Even with tape management software, file access was not intuitive since it required knowledge of what cartridge volume contained the file you needed. And, the standard disk interfaces of operating systems did not enable direct reading and writing to tape cartridges stored in tape libraries. Operating systems were not typically shipped with 'built-in' tape library support.

IBM recognizes that in order to be an attractive, more widely usable storage medium, tape must be as easy to use as the other storage media like disk and removable flash media. This requires a file system interface that behaves like disk, as well as the flash drive-like ability to share data without regard to platform.

Built on the Linear Tape-Open (LTO) Ultrium5 format standard, IBM Linear Tape File System (LTFS) provides direct, intuitive, graphical access to data stored in IBM tape drives and libraries using LTO generation 5, and the new enhanced 3592 cartridges.

Some of its features include:

• Makes tape appear and work like removeable media like USB or removeable drives

Self-Study Booklet

Self-Study Booklet



ALMS new function modified library error log view

Advanced Library Management System (ALMS) has been updated with a new modified library error log view at R11A (Bxxx) code.

• From the system summary screen, service pulldown, select view library error log

• Note the view is different showing multiple entries instead of one log at a time in prior versions

ALMS new function auto eject expired cleaning cartridges

Another new function added to ALMS is a selection to eject expired cleaning cartridges. In the past when a cartridge expired the customer would not find out till a cleaning tape was loaded and a flag was set indicating the cartridge had reached the end of its useable cleaning cycles. Then the cartridge would have to be manually replaced. With this new function when the cartridge expires it will be automatically ejected from the 3584 library.

• From the system summary screen from the library pulldown, select library preferences

• Place a check in the auto-eject expired cleaning cartridges box, then click apply

Uempty 1.2. 3592-E07 overview

The IBM System Storage TS1140™ (machine type 3592, model E07) offers higher capacity and performance over the prior generation 3592 model E06.

3592 E07 highlights

The TS1140 E07 is the next generation of the 3592 enterprise tape drive family. When installed in a TS3500 (3584) library the 3592-E07 requires a minimum library microcode level of R11A (Bxxx code). Some of the 3592 capabilities include:

• Native data rate performance of up to 250 MB/sec (up to 650 MB/sec compressed) versus 160 MB/sec of the TS1130 (3592-E06)

• 8 Gbps dual fibre channel interface

• Encryption designed to work with the IBM Tivoli® Key Lifecycle Manager

The high reliability of the 3592 tape drive and media is maintained and improved with these features:

• Same form factor as 3592 J1A, E05, and E06

• Larger firmware image of ~ 11mb on 3592-E07 versus ~ 6mb on 3592-E06 results in longer drive power on, drive reset, and code update times

• Giant Magneto Resistive (GMR) 32-channel head technology

• Media partitioning capability for improved tape data management

Self-Study Booklet



• Head overcoat technology into tape offers improved head protection and wear characteristics

• Standby power management improvements that automatically reduce fan speed when idle to lower power dissipation and reduce the risk of airborne debris contamination over extended idle periods

New cartridge types

The TS1140 is designed to provide up to 4.0 TB uncompressed capacity with the new IBM tape cartridge 3592 (Type JC) media.

• JC, advanced data cartridge

• JK, advanced economy cartridge

• JY, advanced worm cartridge

• Compatible with E05 and E06 drives, new firmware required for drives to recognize the new cartridges

• New JK type diagnostic cartridge for use only in 3592-E07 drives

3592-E06 to E07 model conversion

The 3592-E06 is upgradeable to a model 3592-E07 by System Service Representatives in the field at the customers site. It requires replacing the following components in the drive cannister assembly:

• Drive brick

• DCJ card (and card brackets)

• Drive brick to DCJ card cables

• Ferrite core

• Labels

Topic summary

This topic covered enhancements that were released with the R11A (Bxxx) version of 3584 microcode. An introduction to the Linear tape file system (LTFS) and noted some of its main features including making tape appear and work at the host like a removeable drive. Advantages include the elimination of any additional tape management software, directories and files show up on the desktop, and files can easily be dragged and dropped to and from the tape. LTFS was designed to be cross platform for easy portability on Mac, Linux, or Windows hosts. The partitioning scheme uses a small partition to hold the index file and a large partition for all the data files. LTFS is a multi vendor effort and expected to become and industry standard.

New ALMS functions were added for a modified library error log view which has a new view showing multiple log entries in a list that are selectable instead of showing the log entries one at a time in earlier versions. The other ALMS function introduced was for auto eject of expired cleaning cartridges.

Highlights of the 3592-E07 and the comparisons made to the prior generation model E06 included native data rate of up to 250mb/sec, 8GB dual FC interface, encryption capability, same form factor as earlier generation drives, new head technology, media partitioning capability, improved head protection, and standby power management improvements. New cartridge types and the 3592-E06 to E07 conversion process was introduced. Course number SE3592E5 is required training for SSRs that will be servicing 3592-E07 tape drives.

The new 8GB FC switches introduced at R11A are only supported in L23, and D23 frames. The 8GB FC switch like the prior 4GB FC switch has 3 sets of LEDs; system, port, and power supply/fan LEDs that show the status of the switch.

V5.4.0.3

Uempty 2.1. Shuttle complex overview

In order to meet the needs of large data center archives that have to store increasing amounts of data, the TS3500 Tape Library offers shuttle technology that enables flexible library growth on a z-axis. This growth flexibility enabled by shuttle connections between HD libraries allows a higher maximum capacity for a single library image of multiple TS3500 library strings. This flexibility also accommodates constrained data center layouts that do not have room to expand on the x-axis, as well as data centers with large archives that exceed the maximum cartridge count of an individual TS3500 Tape Library string. In a TS3500 Tape Library shuttle complex, if the home logical library does not have a drive available, cartridges can be moved to a logical library in a different library string that has an available drive.

The 3584-SC1 transports tape cartridges in shuttle cars that pass over the tops of the libraries. This method of transporting cartridges is called direct flight. With direct flight capability the cartridge is moved from its home logical library across a shuttle connection to the destination logical library. These interconnected parallel library strings are called a shuttle complex.

3584-SC1 features

The features of the 3584-SC1 include:

Expanding libraries on the z-axis and flexibility in configurations that do not have room to expand on the x-axis (reference the following figure)

Self-Study Booklet



A shuttle complex is comprised of between 2 and 15 parallel library strings that are interconnected by shuttle connections between HD frames. Each library string in a shuttle complex has access to one or more shuttle cars that each provide at least one direct route to each of the remote library strings. (At least two direct routes are recommended for redundancy.)

A shuttle complex supports library strings with varying numbers of frames to the left or right of each connection. A shuttle complex also supports shuttle connections with varying numbers of spans. This support enables flexible shuttle complex configurations in order to accommodate most data center arrangements. It is required that the front doors of each library string in the shuttle complex face the same direction.

3584-SC1 feature codes

The prerequisites and feature codes for the 3584-SC1 shuttle complex include:

• Library firmware must be at current recommended Bxxx version

Topic summary

The 3584-SC1 shuttle complex is a method of transporting cartridges from one library to another in shuttle cars that pass over the tops of the libraries. The features include allowing the customer to expand their libraries on the z-axis in configurations that may no longer be able to expand on the x-axis due to room constraints.

Shuttles are attached only to High Density frames and can have a minimum of 1 span and a maximum of 224. The shuttles can be assigned to one logical library or remain unassigned.

Various feature codes and prerequisites are needing to be at the current recommended level of Bxxx code on all libraries attached to a span, ALMs and TSSC are both required, and the short and long span features that allow the customer to install with libraries between 30 and 105” apart.

Shuttle components include the shuttle shuttle station, shuttle car, shuttle span, and shuttle connection. The shuttle station can only be installed on a 3584-Sx4 high density frame. If an SSR needs to get trained on the shuttle complex there is a 2 day instructor led course that the SSR would need to attend (course number S9S03).

Small Computer Systems Interface (SCSI). A standard used by computer manufacturers for attaching peripheral devices (such as tape drives, hard disks, CD-ROM players, printers, and scanners) to computers (servers). Pronounced “scuzzy”. Variations of the SCSI interface provide for faster data transmission rates than standard serial and parallel ports (up to 160 megabytes per second). The variations include:

• Fast/Wide SCSI: Uses a 16-bit bus, and supports data rates of up to 20 MBps.

• SCSI-1: Uses an 8-bit bus, and supports data rates of 4 MBps.

• SCSI-2: Same as SCSI-1, but uses a 50-pin connector instead of a 25-pin connector, and supports multiple devices.

• Ultra SCSI: Uses an 8- or 16-bit bus, and supports data rates of 20 or 40 MBps.

• Ultra2 SCSI: Uses an 8- or 16-bit bus and supports data rates of 40 or 80 MBps.

• Ultra3 SCSI: Uses a 16-bit bus and supports data rates of 80 or 160 MBps.

• Ultra160 SCSI: Uses a 16-bit bus and supports data rates of 80 or 160 MBps.
