With regard to GLVM mirroring, which of the following is a true statement?

IBM GLVM imposes a documented 254-mile maximum distance between production and backup sites to keep round-trip latency within bounds that synchronous mirroring can tolerate without causing I/O timeouts or data inconsistency. This is a hard architectural limit of the RPV (Remote Physical Volume) protocol that underlies GLVM's inter-site communication. Exceeding this distance risks write failures and mirror desynchronization under normal workloads.

GLVM mirroring requires a dedicated, high-bandwidth, low-latency network connection - not arbitrary standard TCP/IP infrastructure - because the RPV protocol's synchronous write requirements impose strict network quality constraints that a general TCP/IP network cannot reliably guarantee.

GLVM mirroring is fully transparent to applications because it operates at the LVM layer of the OS; no application needs to be coded or configured as mirror-tolerant since AIX handles all mirror synchronization below the application stack.

GLVM does not require identical IBM Power System server models at both sites - differing hardware generations are supported as long as AIX and GLVM version compatibility is maintained between the two sites.
