A storage administrator is investigating non-linear variations in throughput when zoning additional hosts to certain front-end adapters. They notice a certain performance characteristic having 10 identical hosts zoned to the same FA ports. After adding the 11th host, the throughput sometimes drops more than 20%.
What is the most likely cause of this behavior?
A storage administrator migrated an AIX host using NDM.
When they commit the migration, how is host access to the source array removed?
An administrator implemented SYMACLs on a PowerMax using host-based Access IDs. The administrator is no longer able to run SYMCLI commands against the volumes belonging to a host.
What is a possible reason for this issue?
A host is issuing I/O to a PowerMax.
What happens if the cache space fills up?
When the cache space fills up, I/O will be queued until an empty cache slot is available. This is because PowerMax operates as a cache-centric architecture, where all data is passed through cache before being stored on disk. Cache is used to buffer incoming and outgoing data, as well as to support various functions such as replication and data reduction. When cache is full, the array cannot accept any more data until some cache slots are freed up by flushing data to disk or invalidating stale data. Therefore, answer B is correct.
A, C, and D are incorrect because they do not describe what happens when cache space fills up. I/O will not be serviced at the speed of the destination device (A), as this would bypass the cache and degrade performance. Cache is not permanently flushed or temporarily disabled (D), as this would result in data loss or corruption.
A disaster occurred at the workload site of an SRDF/Star configuration. The administrator decides to move the workload to the Synchronous site (Site B).
What symstar command should be used before the workload switch?
