  • Page 25: About Volume Cache Options

    You can optimize a volume for sequential reads or streaming data by changing its read-ahead cache settings. Read ahead is triggered by two back-to-back accesses to consecutive LBA ranges, whether forward (increasing LBAs) or reverse (decreasing LBAs). HP StorageWorks P2000 G3 MSA System SMU Reference Guide...

  • Page 26: Related Topics

    You can change the amount of data read in advance after two back-to-back reads are made. Increasing the read-ahead cache size can greatly improve performance for multiple sequential read streams; however, increasing read-ahead size will likely decrease random read performance. •...

    3. On completion, the new volume is a completely independent copy of the snapshot. The snapshot remains, though you can choose to delete it. Figure 3 Creating a volume copy from a master volume or a snapshot HP StorageWorks P2000 G3 MSA System SMU Reference Guide...

  • Page 30: Related Topics

    Snapshot operations are I/O-intensive. Every write to a unique location in a master volume after a snapshot is taken will cause an internal read and write operation to occur in order to preserve the snapshot data. If you intend to create snapshots of, create volume copies of, or replicate volumes in a vdisk, ensure that the vdisk contains no more than four master volumes, snap pools, or both.

If you delete the current sync point, then if a replication-set failure occurs, a prior sync point will be used. If you delete the only sync point then the next replication will require a full sync to be performed (all data to be re-replicated from the primary volume to a secondary volume).

    This sync point can be used to determine the delta data from that sync point to a later snapshot. Actions 1–4 are the initial replication. HP StorageWorks P2000 G3 MSA System SMU Reference Guide 107...

    • Delta replications: Delta data is the “list” of 64-Kb blocks that differs between the last snapshot replicated and the next snapshot to be replicated. This delta data is then replicated from the replication snapshot on the primary volume to the secondary volume. Once the initial replication has completed, all future replications for that replication set will be delta replications so long as sync points are maintained.

    NOTE: Normally, if you want to remove a replication set you must select its primary volume. However, if the primary volume is inaccessible, you can set the secondary volume to be the primary volume (as described in Changing the primary volume for a replication set on page 1 17) and then perform a Remove Replication Set operation.
