You design and size an HPE StoreViriual solution for an SMB customer environment according to these
requirements
High availability between two data centers is needed
3 TB of data should be replicated
2×1 Gb/s links are needed between Sites A and B
A round trip time of 1.8 ms is needed between sites A and B
A third site, Site C, is needed for Failover Manager (F OM) connected with 100 MB/s
There is a latency of 55 ms between Site C and the other sites.
Which potential issue be discussed the customer before proposing the HPE StoreVirtual solution?
A.
Maximum latency requirements are not met for Site C
B.
Maximum bandwidth requirements between Site C and B are not met
C.
Maximum round trip time for Sites A and B is not met
D.
Maximum bandwidth requirements for Site C are not met
B. Maximum bandwidth requirements between Site C and B are not met
0

A.Maximum latency requirements are not met for Site C
Limite of lantency is 50

Answer is A, as FOM needs 100MB/s bandwidth and 5ms latency
0

HP StoreVirtual Storage technical whitepaper says on page 22:
HP StoreVirtual Fail-Over Manager (FOM) is not in the data path and has to be connected using at least Fast Ethernet connections (100 Mb/s) with a latency not exceeding 50ms. No iSCSI data traverses between storage nodes and the FOM.
