FC switch requirementsFor additional B-series and C-series FC switches, local and remote MPX200 Multifunction Router pairsmust be connected to the same Fibre Channel switch product line series.NOTE:The MPX200 Fibre Channel ports operate at 2, 4, and 8 Gb/s.IP network requirementsHP requires that the following standards be met for the IP network:• Supported network protocols are TCP/IP IPv4 and IPv6 Ethernet 1,000 Mb/s.See EVA storage system rules and guidelines, page 113 for minimum IP bandwidth requirements.• For MPX200 IP data—Local and remote pairs are supported for up to 100 ms of IP network delayone-way, or 200 ms round-trip for HP Continuous Access EVA. HP requires dedicated IP bandwidth(see Table 14).• For MPX200 IP management—LAN and WAN are supported.Table 14 Network requirements for the MPX200 with XCS and VCSDescriptionSpecificationMust be dedicated to the HP Continuous Access storage replica-tion Bandwidth function. There is no support for dynamic pacingof the gateway.Bandwidth1See Table 13 for minimum supported bandwidth based on theaverage maximum number of DR groups packet-loss ratio andone-way intersite latencies.Maximum number of DR groups1,500 bytesMTU of the IP networkEVA: 100 ms one-way or 200 ms round-tripMaximum latency1Low-loss network: 0.0012% average over 24 hoursHigh-loss network: 0.2% average over 24 hours; must not exceed0.5% for more than 5 minutes in a 2-hour windowAverage packet-loss ratio2Must not exceed 10 ms over 24 hours.Latency jitter31Pre-existing restriction2A high packet-loss ratio indicates the need to retransmit data across the intersite link. Each retransmissiondelays transmissions queued behind the current packet, thus increasing the time to complete pendingtransactions.3Latency jitter is the difference between the minimum and maximum values, and indicates how stable orpredictable the network delay. The greater the jitter, the greater the variance in the delay, which lowers theperformance predictability.MPX200 FCIP114
