Max. distance between c7000 eclosure's when stacking?

[rrzatc]

Hi all,

does anybody know the max distance between two c7000 enclosures wihtin a VC domain?

I got two enclosure approx. a half mile away from each other. I want to stack them into a single domain to seperate east-west traffic from the core switches.

Thanks for your help!

For longer distances as stated above, it is recommended to use optical fibre cable for stacking.

For the following Virtual Connect modules this would be possible. Review Related Options > Cabling and Transceiver Options > "Ethernet Optical Transceivers" in their respective QuickSpecs for part number for transceivers:

For HP 1/10Gb-F Virtual Connect Ethernet Module for c-Class BladeSystem, the connectivity is only upto a maximum of 300m. Refer it's QuickSpecs.

HP 1/10Gb Virtual Connect Ethernet Module for c-Class BladeSystem does not support stacking as this lacks the computing resources.

For shorter distances the following would be sufficient:

VC-Enet modules support 0.5 m to 7 m (1.64 ft to 23.00 ft) 10GBASE-CX4 stacking cables. The 1000BASE-T links can also be used as stacking links of up to 100 m (328 ft). Ports with different connector types can be aggregated if the link speed is the same. For example, CX4 and SFP+ ports both running at 10G can be aggregated to provide enhanced throughput for the stacking link.

FlexFabric modules support DAC cables. Uplink ports X1-X4 only support 0.5 m to 5m (1.64 ft to 16.40 ft) DAC stacking or uplink cables. Uplink Ports X5-X8 support 0.5 m to 7 m (1.64 ft to 23.00 ft) DAC stacking or uplink cables.
