 ENUS202-033.PDF (40KB)


At a Glance

IBM Automated Tape Allocation Manager provides unattended management of tape storage availability. It works directly with tape control unit hardware to ensure that idle tape storage devices are fully accessible on demand.

Automated Tape Allocation Manager:

  • Reduces storage I/O bottlenecks, and eliminates idle time for valuable tape resources
  • Keeps tape units free for use across multiple images, and minimizes backlogs of job requests
  • Reduces or eliminates the need for operator intervention in tape unit allocation
  • Assists tape resource planning with extensive performance reports
  • Allows dynamic change of configuration parameters without downtime
  • Automatically and reliably manages contention for tape unit resources through direct communication with tape drive unit control blocks (UCBs)
  • Provides fast implementation with an ISPF panel interface and online help
  • Fits any z/OS or OS/390 environment

Overview

IBM Automated Tape Allocation Manager supports maximum I/O of your existing tape hardware capacities. It reduces or eliminates idle time for tape drive units servicing multiple images.

Instead of images establishing and unnecessarily holding connections to tape drive units (and excluding other images from using those tapes), Automated Tape Allocation Manager patrols the use of tape drives making certain that any idle tape units are available to new incoming requests from jobs and end users.

Extensive reporting on tape drive usage supports capacity analysis. The result is higher throughput to and from tape, a more efficient storage environment, less administrative overhead, and better returns on tape hardware investments.

Key Prerequisites

Automated Tape Allocation Manager can be used on any supported release of z/OS™ or OS/390®. When used with 3480 tape drives, it requires Model G or later drives.

Planned Availability Date

February 22, 2002

Description

Contention for tape resources in mission-critical dataplexes can create problems for businesses:

  • Long wait times for application or process execution, and delay of related business processes
  • Significant operator attention to balancing tape storage needs against available resources
  • Pressure to purchase costly excess tape unit capacity, without a full understanding of how it will be used
  • Longer ROI on hardware investments

Automated Tape Allocation Manager is a z/OS storage solution that directly addresses these problems by managing tape storage availability for optimal usage, 24 x 7 across multiple images, and by logging and reporting tape demand activity and the success rate of its fulfillment.

Maximum Capacity Utilization

Tape sharing management ensures that tape resources do not sit idle waiting for responses from data images, jobs, or users that have allocated them for use but no longer have I/O to process. With contention for tape resources issuing from potentially thousands of simultaneous sources, recurring idle times of even a few seconds each can result in significant accumulated waste, noticeable bottlenecks, and premature addition of new hardware due to perceived ceilings in capacity that may not yet have been reached.

Manual detection and intervention in such situations is labor intensive and impractical, as operators will often be unable to respond to an idle time "window" before it closes, or may simply be unavailable at all for such tasks.

Automated Tape Allocation Manager solves these problems by responding to actual user and job requests for tape resources and varies offline those units that may be allocated but not in actual use. Response is nearly instantaneous, and eliminates the need for any operator intervention.

Designed to fit any z/OS, OS/390, or MVS™ environment, Automated Tape Allocation Manager can be tuned and configured to respond to your changing work loads and priorities, and these configurations can be changed dynamically without any downtime in the product's operation through the easy-to-use ISPF panel interface and accompanying online help.

Simplified Strategy for Performance and Reliability

Available software solutions for tape sharing management typically follow the strategy of continually updating a control file that records tape drive status, and then taking action based on what can be read from that control file. However, this approach requires successful communication (through CTC or other methods) between the control file and multiple dataplexes and their respective UCBs before corrective action can be taken. This presents issues in installation, administration, and performance management. Potential vulnerabilities also arise since every instance of managed tape allocation for the enterprise is made dependent upon the integrity of a single control file which may have no special protections and the function of which may be poorly understood by operators.

Automated Tape Allocation Manager instead takes a more hardware-centric approach through a started task that — at set intervals or in response to actual user and job requests — issues commands to vary offline each successive tape drive unit placed under its management by the operator.

Tape drives that are in actual use elsewhere will not vary offline, and those allocated but not in use will vary offline immediately, making the next job or user request for them successful. Tape availability is maximized without resorting to prior knowledge of a tape resource's status, complex communication across dataplexes and subsystems, or centralized control files.

Automated Tape Allocation Manager operational parameters are easily adjusted by the operator and can be changed dynamically, leaving enterprise tape management uninterrupted. Management parameters (such as units to be managed in which dataplex, or frequency of polling) are stored in a parameters file that is read by the tape management task at startup, and these parameters persist within the started task independent of the parameters file. Should the parameters file ever not be found at startup, the restarted tape management task will assume the last known issued parameters, assuring proper functioning in unexpected circumstances.

Administrators can expect superior reliability and near-machine speed performance from Automated Tape Allocation Manager.

Detailed Capacity Analysis

At the same time, operators may use the Automated Tape Allocation Manager reporting facility to view the current or historical status of any tape drive, and analyze these reports to better plan capacity. Through the Automated Tape Allocation Manager report facility, management of current or future hardware ROI is made far easier.

Available reports include:

  • All recorded tape unit activity
  • Tape activity by job and step
  • Usage by tape unit
  • Records of failed automatic allocations

Importantly, report detail allows you to assess if, when, and how often jobs must wait for a drive, respond quickly to end user needs, and alleviate bottlenecks by configuring Automated Tape Allocation Manager to better balance jobs against tape resources.

The current status of any drive is also instantly available, assisting with real-time decision making.

With this level of detail and capacity for quick response, administrators achieve much higher confidence in investment decisions should the need for new hardware ever arrive.

Value Unit Based Pricing

Value Unit based pricing will help to align the prices of these Products to the principle of the PSLC pricing curve which provides for a lower price per millions of service units per hour (MSU) for larger capacities.

There is also be a price benefit when customers grow their capacity. Additional capacity will based on the number of Value Units (MSUs) the customer has already installed, that is, additional capacity will not be priced starting at the base with a higher price per unit but on the capacity that is already installed.

Note that Value Units of a given Product cannot be exchanged/interchanged/aggregated with Value Units of another Product.

IPLA and Subscription and Support Considerations

IPLA licenses can be transferred from one machine to another within, but not limited to an enterprise. The customer may aggregate the capacity for all the processors the Product is operated on to achieve a more economic price. This will result in a single Proof of Entitlement. It is the customer's responsibility to manage the distribution of Value Units within the limits of the Entitlement of the Product License.

Subscription and Support must cover the same capacity as the Product License entitlement. Subscription & Support will be available in the country in which the agreement is made.

Product Positioning

Automated Tape Allocation Manager will be of interest to any z/OS or OS/390 customers who need to share and maximize availability of tape drives across multiple images. Automated Tape Allocation competes with third party vendor products such as Computer Associates Multi Image Allocation product (CA MIM/MIA).

Translation from MSUs to Value Units
 
                  MSUs            Value Units
 
Base              1-3                 1.00
Tier A            4-45                 .45
Tier B           46-175                .36
Tier C          176-315                .27
Tier D            316+                 .20

The total number of Value Units is calculated according to the following example:

If the customer has installed 1,000 MSUs the applicable Value Units would be:

3 * 1.00 + 42 * 0.45 + 130 * 0.36 + 140 * 0.27 + 685 * 0.20 = 244 Value Units

When calculating the total number of Value Units the sum is to be rounded up to the next integer.

Value Units for IBM 9672 Processors will be based upon the full capacity of these Systems. This is applicable to all S/390® based Systems that are measured on MSU capacity. Information on MSU capacities can be found in the IBM System/370™, System/390® and zSeries Machine Exhibit (Z125-3901).

Value Units for IBM e(logo)server zSeries will be based upon full MSU capacity as defined in the Machine Exhibits

Value Units for non-MSU-based S/390 Processors: MP3000 Models

  • H30 = 6.00 Value Units
  • H50 = 8.00 Value Units
  • H70 = 12.00 Value Units
  • P/390, R/390, IBM 3006 = 2.00 Value Units

A tool is available that provides support for transforming the MSU based capacities of S/390 Systems to new Value Units by calculating the applicable number of Value Units for a given number of MSUs. The person preparing for an order is required to use this tool to calculate the number of Value Units, based upon the number of MSU (processor capacity). CFSW expects Value Units as configuration input.

Customized Offerings

Product media is shipped only via Customized Offerings (that is, CBPDO, ServerPac, Systempac®). Non-customized items (CDs, diskettes, source media, media kits) will continue to be shipped via the stand-alone product.

Terms and Conditions

Sub-Capacity Charges Terms and Conditions: zSeries software charges at less than full machine capacity for eligible Data Management and Application Development Tools apply when z/OS is running in z/Architecture (64 bit) mode on an IBM e(logo)server zSeries 900, no other MVS™-based operating system is licensed to that server and the required information is provided by the customer in accordance with the applicable terms.

Sub-capacity charges for an eligible AD or DM Tool is based on the z/OS product defined capacity. To obtain charges at less than full machine capacity for eligible AD and DM tools, the customer is required to:

  • Determine the MSUs needed for each machine on which the Tools will run. Only machines on which the customer has implemented sub-capacity WLC according to the above terms and conditions, are eligible for charges at less than full machine capacity for the Tools.
  • Use the product defined capacity for z/OS (as specified on the Sub-Capacity Reports submitted to IBM for sub-capacity WLC) as the sub-capacity(MSUs)for each Tool.
  • Submit any additional MSUs and/or Value Units required for each product along with the current entitlement in Value Units for each Product.

Sub-Capacity Charges for AD and DM Tools: To be eligible for sub-capacity charges for AD and DM Tools, the Machine on which the AD and DM Tools are running must be eligible for WLC sub-capacity charges terms and conditions. The customer must have signed the Attachment for zSeries Workload License Charges-Pre-ILM , (Z125-6516), and submitted at least one Sub-Capacity Report to IBM as defined in the attachment.

With sub-capacity charges, the charge for an eligible AD or DM Tool is based on the z/OS product defined capacity. To obtain charges at less than full machine capacity for each eligible AD and DM Tool for each machine, the customer should:

  • Determine the MSUs needed for the machine on which the Tools will run. In a data sharing environment, determine the aggregate MSUs needed on the machine where the tools run. Use the product defined capacity (MSUs) for z/OS (as specified on the Sub-Capacity Reports submitted to IBM for sub-capacity WLC) as the sub-capacity (MSUs) for each Tool.
  • Submit any additional MSUs and/or Value Units required for each product along with the current entitlement in Value Units for each product.
  • If the use of sub-capacity pricing terms for AD and DM Tools results in a reduced requirement for Value Units, thus "freeing up" entitlements, customers can reallocate the entitlement difference by distributing the Value Units across a larger or different set of systems, or reserve them for future growth. There will be no refunds for these "freed up" Value Units. Subscription and Support volumes and entitlements for existing contracts will continue to be at the same levels as the acquired licenses.

Management of the Value Unit entitlements continues to be a customer responsibility. If one of the following occur on a machine to which AD or DM Tools are licensed, the customer must determine if additional Value Units and Subscription and Support need to be ordered for those Tools to cover the increase:

  • The z/OS defined capacity is increased.
  • The requirements for WLC sub-capacity charges are no longer met.

Licensing: IBM IPLA PoE are required for all authorized use. Part number products only, offered outside of Passport Advantage, where applicable, are license only and do not include Software Maintenance.

The following agreements apply for maintenance and do not require customer signatures:

  • IBM Agreement for Acquisition of Support (Z125-6011)
