Regarding the description of the technical principle of the DCL small bitmap in remote replication, which items are incorrect of ?

The small bitmap technology can reduce the amount of data copying and the risk of data loss, and improve the copy performance.Reduce RPO.

Small bitmap technology splits a 64KB Chunk into 16KB Chunk with smaller granularity to remember Record the difference.

Small bitmap technology can be applied to asynchronous remote replication.

The small bitmap technology can reduce the amount of data copying and the risk of data loss, and improve the copy performance.Reduce RPO.

Small bitmap technology splits a 64KB Chunk into 16KB Chunk with smaller granularity to remember Record the difference.

According to the principle of small bitmap technology, when there are 6 consecutive different data addresses that need to be synchronized, The granularity of the copy at this time is 4KB.

Regarding the HyperMetro static priority arbitration mode, the correct one is:

When an inter-array link failure occurs, or a non-priority site fails, the LUN on the priority site continues Services will continue to be provided, and LUNs at non-priority sites will cease to provide services.

When the priority site array is powered off for maintenance, the non-priority site array immediately takes over all active-active businesses The business will not be interrupted.

When the priority site array fails, the non-priority site will automatically take over the activeactive service.

The static priority mode has higher reliability than the quorum server mode.

When an inter-array link failure occurs, or a non-priority site fails, the LUN on the priority site continues Services will continue to be provided, and LUNs at non-priority sites will cease to provide services.

When the priority site array is powered off for maintenance, the non-priority site array immediately takes over all active-active businesses The business will not be interrupted.

When the priority site array fails, the non-priority site will automatically take over the activeactive service.
