Hi,
If I have an OSD attached by a FC SAN device with the connection like this:
OSD HBA-->FC Switch-->SAN storage device.
Then Map a LUN in the SAN to the OSD as its only disk device to save
data. if I have a client also has an HBA and the topology diagram looks
like:
osd client
------- ------- -------
-------
| HBA | | NIC | <---------------> | NIC | | HBA |
---+--- -------- ------- -------
\ /
\ /
\ /
\ --------------
| FC Switch |
--------------
|
SAN
Suppose the created LUN above for OSD can be accessed by both osd and
client though FC I/F, the question is:
if I create a rbd block device in osd and map it to client, make a file
system and mount it in client side, then create a file in the mounted
FS. The read/write operation followed for this file will transfer data
though ethernet path or FC path?
BRs,
Dennis
