8464ch04_Planning.fm Draft Document for Review February 7, 2020 3:15 pm Note:  If external key management is later enabled, these USB sticks are no longer  needed.  The External Key Encryption (FC 5276) must have FC 5272 installed on the TS7770 server  before initial installation. Consider the following points: GLYPH<SM590000> All TS7700 configurations with any encryption type enabled is always shipped with local  key management enabled first. GLYPH<SM590000> After a TS7770 with FC 5272 is configured in a customer environment and can  communicate with an external key server, FC 5276 can be activated to transition to  external key management. External key management can be concurrently enabled after the TS7770 is installed in  customer site. Only distributed version of ISKLM are supported (not z/OS). KMIP is used for  the protocol. Connection is TLS 1.2 protected. 4.5 Tape analysis and sizing the TS7700 4.5.1 IBM tape tools This section documents the process of the use of various tools to analyze current tape  environments and to size the TS7700 to meet specific requirements. It also shows you how to  access a tools library that offers many jobs to analyze the current environment, and a  procedure to unload specific System Management Facility (SMF) records for a  comprehensive sizing with  BatchMagic , which must be done by an IBM SSR or  IBM Business Partner. Although most IBM tape tools are available to you, some tools, such as BatchMagic, are  available to IBM personnel and IBM Business Partners only. You can download the tools that  are generally available from this IBM Software FTP web page. The web page features a list of  .TXT ,  .PDF , and  .EXE  files. To start, open the  OVERVIEW.PDF  file  to see a brief description of all the various tool jobs. All jobs are in the  IBMTOOLS.EXE  file,  which is a self-extracting compressed file. After this file is downloaded to your PC, you can  expand it into the following files: Two areas of investigation can assist you in tuning your current tape environment by  identifying the factors that influence the overall performance of the TS7700. An example of  factors is bad block sizes; that is, smaller than 16 KB, and low compression ratios, both of  which can negatively affect performance. System Management Facilities (SMF) is a component of the mainframe z/OS that provides a  standardized method for writing out records of activity to a data set. The volume and variety of  information in the SMF records enable installations to produce many types of analysis reports  and summary reports.
