How to manually set the speed of an FC-VI card in a Stretched MetroCluster to 2G, 4G or 8G
Applies to
- Streched MetroCluster
- ONTAP 8
- ONTAP 9
Description
In a Stretched MetroCluster configuration the use of an FC-VI card for the HA Interconnect is mandatory. Currently the following FC-VI cards are supported.
- X1927A-R6 - 2/4/8G FC-VI, connecting at 8G by default, does not support Single Mode SFP
- X1928A-R6 - 4/8/16G FC-VI, connecting at 16G by default
Note: For more details on which platforms a specific FC-VI card is support please refer to the HardWareUniverse (HWU)
Note: Only the FC-VI card X1928A-R6 support Single Mode SFP.
The following distance limits apply for different speeds, depending on cable quality:
| Speed | OM2 | OM3 |
OM3+,OM4 |
Single Mode (OS1/OS2) |
| 2 | 300 | 500 | 500 | 500 |
| 4 | 150 | 270 | 270 | 500 |
| 8 | 50 | 150 | 170 | 500 |
| 16 | 35 | 100 | 125 | 500 |
For the latest information on distance support for Stretched MetroCluster, see the current MetroCluster Compatibility Matrix.
By default, the FC-VI card connects at the highest common speed of both cards. However, to achieve longer distances, the connecting speed of the FC-VI card might have to be set to speeds lower than the maximum speed supported by the card.
