Short description
• This presentation contains information and graphs about the performance and capacity of a TS7700 virtualization engine
• This will show the statistics for only one cluster (even if in a multi-cluster grid)
• If you want the views from other clusters in the grid, you will need to generate separate presentations for each cluster
3
Agenda• This presentation contains the following sections: In PowerPoint, right click
on the section name and then “Open Hyperlink” to go directly to the beginning of that section.
– Overview– Data transfer– Virtual mounts– Virtual mount times– Virtual Drive and Physical Drive usage– Physical mounts– Physical mount times– Data compression ratios– Blocksizes– Tape Volume Cache performance– Throttling– Multi cluster configuration (Grid)– Import/Export Usage– Capacities: Active Volumes and GB stored– Capacities: Cartridges used– Pools (Common Scratch Pool and up to 4 Storage Pools )

Preliminary notes
• In each section:• First will be shown the daily values for
the period of analysis • Second will be shown the hourly values
for a selected day. The hour on the axis is the end-of-hour time.
• To further differentiate these from the daily charts, the hourly charts will have headers in this dark blue color.

Blocksize• Performance depends on the block size used. The
bigger, the better. The following chart shows information about the block sizes used. The block size ranges are: – Less than or equal to 2KB– Less than or equal to 4KB– Less than or equal to 8KB– Less than or equal to 16KB– Less than or equal to 32KB – Less than or equal to 64KB– Greater than 64KB
• The chart shows the percent of total blocks for each block size range.

Tape Volume Cache Performance• Tape Volume Cache Management may be used to influence the use of the
Tape Volume Cache (TVC). This can be done with the Storage Class attribute. This parameter selects Preference Groups (PG0 or PG1).
• With no usage of IART, all volumes default to PG1.• PG0
– Preferential early removal of volumes from cache, largest first.– IART >= 100
• PG1– Removal of volumes after PG0, least recently used first.– IART < 100
• The following charts show:– Number of virtual volumes in cache (PG0 and PG1)– Amount of GB (compressed) in cache (PG0 and PG1)– Duration in cache in hours, separated for PG0 and PG1– Number of virtual volumes removed from cache in the last 4 hours and the last
48 hours, separated for PG0 and PG1

Throttling• Throttling will be occur if the amount of data exceeds
certain thresholds. This is only a simplified definition. The redbook SG24-7312, Chapter 8, Performance and monitoring contains a detailed description of throttling.
• The following charts show if there is – Write throttling (Data arriving faster than can be migrated to
tape)– Copy throttling (Data arriving faster from other clusters than can
be migrated to tape)– GB to Migrate queue (1.5 only)
• These values are the maximum for the day.• Zeros is the best case. Return to Agenda

Capacities: Cartridges used• First there will be an overview about the maximum and
minimum number of cartridges per type in the whole period.
• Following are charts about the usage of each type of cartridge, private and scratch – 3592JJ (60 GB, 100 GB, or 128 GB raw capacities)– 3592JA (300 GB, 500 GB, or 640 GB raw capacities)– 3592JB (700 GB or 1000 GB raw capacities)
• Capacities vary with the model of the 3592 drive used• If all values of a chart are zero, this cartridge type isn't in
use.• Only daily charts will be shown for cartridges
