  • Page 19: Introduction

    1 Introduction With CentricStor, a virtual tape robot system is placed in front of the real tape robot system (with the real drives and cartridges). In this way the host and the real archive are fully decoupled. The virtual tape robot system knows what are referred to as virtual (logical) drives and virtual (logical) volumes.

  • Page 20: Objective And Target Group For The Manual, Concept Of The Manual

    Objective and target group for the manual The host is connected using the following connection technologies: ESCON channels ● FibreChannel ● FICON ● Communication between the individual control units takes place via the LAN in CentricStor, the transport of the user data to and from the RAID system via the FibreChannel. The physical drives can be connected to the backend via both FibreChannel and SCSI technology.

    Introduction Global Status The Global Status Monitor provides a graphical display of all important operating data in a window. XTCC The program XTCC is used mainly to monitor the individual CentricStor computers (ISPs) including the peripheral devices connected to the computers. Explanation of console messages This chapter describes the most important of the console messages.

    2 CentricStor - Virtual Tape Library 2.1 The CentricStor principle Conventional host robot system Host Figure 1: Conventional host robot system In a conventional real host robot system, the host system requests certain data cartridges to be mounted in a defined real tape drive. As soon as the storage peripherals (robots, drives) report that this has been completed successfully, data transfer can begin.

    The CentricStor principle Host robot system with CentricStor Host Figure 2: Host robot system with CentricStor With CentricStor, a virtual archive system is installed upstream of the real archive system with the physical drives and data cartridges. This enables the host to be completely isolated from the real archive.

    CentricStor - Virtual Tape Library As soon as a mount job is issued, the Library Manager checks whether the requested volume is already in the disk cache. If so, the volume is immediately released for processing by the application. If not, CentricStor requests the corresponding cartridge to be mounted onto a physical drive, and reads the logical volume into the disk cache.

These processors are referred to collectively as the ISP (Integrated Service Processor). Depending on the peripheral connection, the hardware configuration, the software configuration, and the task in the CentricStor system, a distinction is made between the following processor types: –...

To optimize performance, only two real tape drives should be configured per IDP.

  • Page 30: Raid Systems For The Tape Volume Cache

    Hardware architecture 2.2.2 RAID systems for the Tape Volume Cache A TVC (Tape Volume Cache) is the heart of the entire virtual archive system. It represents all of the Tape File Systems in which the logical volumes can be stored temporarily. One or more RAID systems (up to 8) are used for this.

  • Page 31: Fibrechannel (fc), Fc Switch (fibre Channel Switch)

    CentricStor - Virtual Tape Library The metadata of the logical volumes to be written or read is stored on the 1st RAID system, as a result of which the usable capacity of this RAID system is reduced by 16 GB. A CentricStor can contain up to 8 RAID.

  • Page 32: Host Connection, Software Architecture

    Software architecture This SAN-based design means that each CentricStor component is in a position to access the TVC. 2.2.5 Host connection The host connection on the ICP is implemented using the following connection technologies: Host system Mainframe Open Systems FibreChannel with ESCON or FICON connections can be operated in mixed mode on an ICP.

Although the software can be activated on any of the ICP or IDP systems, it is recommended for perfor- mance reasons that you either provide a separate VLP, or activate the components of the VLP on one of the IDPs, since the CPU utilization is at its lowest here.

    Software architecture VLM (Virtual Library Manager) Each robot job from the requesting host system is registered in the VLM. To support the libraries, corresponding emulations (VLMF, VAMU, VACS, VDAS, VJUK) are used in CentricStor. The TVC is administered exclusively by the VLM. The VLM data maintenance contains the names of the logical volumes with which the TVC is to work.

    CentricStor - Virtual Tape Library 2.4 Operation CentricStor is operated via the graphical user interfaces GXCC (Global Extended Control Center) and XTCC (Extended Tape Control Center). These are used to perform all administration and configuration tasks. Using this control center, it is possible to display the current operating statuses of all CentricStor components, together with a large amount of performance and utilization data.

    Selected system administrator activities Only physical volumes in read status on which the relative proportion of valid data is less than the percentage value configured in the Fill Grade parameter are taken into account. If a physical volume is in write status and the percentage value for its valid data drops below the Fill Grade value, it is placed in read status and is therefore a candidate for reorganization.

    Reorganization 4.4.5 Own physical volumes for reorganization backup The PLM distinguishes between backup requests from the host and backup requests which are caused by a reorganization.

It must be ensured that a dependency on the number of available drives exists and that not too many reorganizations take place in parallel, otherwise these will be delayed unneces- sarily on account of the lack of drives.

    Reorganization When the percentage of valid data on a physical volume which is in write status and is not currently mounted in a Physical Device Service is below this limit value and at the same time a reorganization is in progress because a scratch tape limit value has been fallen below, this physical volume is placed in read status, and it is therefore a candidate for reorganization.

    Technical design In this configuration GXCC runs on the remote computer (e.g. Windows PC) and uses the interfaces of its user interface directly. At short intervals GXCC inquires of the CentricStor VLP whether there is new data. Here only 20 bytes are transferred. If new data is available, the VLP sends the GXCC user data to the remote computer, which edits the data and forwards it to the output screen.

    Appendix If the VLM does not know the LV, no restore command is issued to the PLM for the purpose of actually reading in the LV. The PLM therefore waits for an unlimited time, and no progress can be recognized when you query the jobs (plmif query -j -G TR-PVG). You can then either create this LV in the LVG, or skip this LV using the transfer-in cancel command (see the Options...

    Glossary Header At the start of each physical tape written by CentricStor there is an 80-byte header followed by a Tapemark. In the CentricStor system the ICP is the interface to the host systems connected. These are connected using ESCON, FICON or FCP. The ICP’s principal task is to emulate the physical drives for the host systems connected.
