Draft Document for Review February 7, 2020 3:15 pm 8464ch07_Upgrade.fm – The first 200 TB of the base frame is enabled through 10 20 TB increments. Then,  201 TB - 2.3 PB is enabled in 100 TB increments. – At least 1 TB of licensed capacity must be enabled on the next set of drawer pairs  (through FC 5262 and 5263) before the next drawer pair can be installed. Adding  physical drawer pairs without at least 1 TB of licensed capacity enabled is not  supported.  – Feature numbers 5262 and 5263 should be ordered on 3957-VED – At least one feature number 5262 for 20 TB cache enablement increment minimum  must be plant-installed. GLYPH<SM590000> Enable 1 TB Active Premigration Queue capacity (FC 5274) GLYPH<SM590000> Enable 16 Gb FICON second port. Use FC 3401 GLYPH<SM590000> Incremental data throughput GLYPH<SM590000> Selective Device Access Control GLYPH<SM590000> Increased logical volumes Each instance of FC 5274 (Enable 1 TB Active Premigration Queue Capacity) enables up  to 1 TB of data to be pending migration to physical tape or cloud storage tier. Up to 10  instances can be installed. Each instance of FC 5279 (Enable 5 TB Active Premigration Queue Capacity) enables up  to 5 TB of data to be pending migration to physical tape or cloud storage tier. Up to 10  instances can be installed after 10 instances of FC 5274 are installed for an active  premigration queue size to 60 TB and higher. GLYPH<SM590000> Enable 5 TB Active Premigration Queue Capacity (FC 5279) You can add a 100 MBps increment of peak data throughput, up to your system’s  hardware capacity. When the maximum number of performance increments are installed,  the system no longer restricts performance. Use FC 5268 (100 MBps increment) to  achieve this upgrade. The maximum number of features 5268 is 39. This installation is  performed through the TS7700 MI by entering the license key that is obtained with the  purchase of FC 5268 (100 MBps increment). You can grant exclusive access to one or more logical volume ranges by only certain  logical control units (LCUs) or subsystem IDs within a composite library for host-initiated  mounts, ejects, and changes to attributes or categories. Use FC 5271, Selective Device  Access Control (SDAC) to add this upgrade.  Consideration:  The feature must be installed on all clusters in the grid before the  function becomes enabled. The default number of logical volumes that is supported is 1,000,000. You can add support  for extra logical volumes in 200,000 volume increments by using FC 5270. Up to a total of  4,000,000 logical volumes are supported by the maximum quantity of 15 FC 5270  components. 266  IBM TS7700 Release 5.0 Guide
