VPLEX Close to Storage
We are strungling with rackspace for our new EMC equipments based on VMAX and VPLEX. So, Rackspace is an issue here. My questions are: Is VPLEX connected directly to VMAX and what is the max distance of the fibers allowed. In other words should it be wise putting those two racks (VPLEX and VMAX) next to each other.

Please consider moving this question as-is (no need to recreate) to the proper forum for maximum visibility. Questions written to the users' own "Discussions" space don't get the same amount of attention and can go unanswered for a long time.
You can do so by selecting "Move" under ACTIONS along the upper-right. Then search for and select: "VPLEX".

I'm no VPLEX expert, but my guess is that you need to stay within the limits of the patch fibers you're using, just like your hosts. As long as you don't place your VPLEX miles away from your array I wouldn't worry too much. Keep it somewhere in the neighborhood, so if that's max 10, 15 racks from the array you are fine.

VPLEX backend and frontend ports are cables to your FC switches. The BE ports are zoned to your storage arrays, and the FE ports are zoned to your hosts. There are no explicit distance requirements for VPLEX Local FC cabling that I'm aware of, beyond the standard distance limits for 8gbit multimode FC -- 50 meters for 8gbit on 50 micron OM2 cables, or 150 meters for 8gbit on 50 micron OM3 cables.

How paranoid can you be?
Did it ever matter if a fiber patch was 10m or 50m?
But you're right, it's a safe assumption. Let's wait a bit more to see if somebody jumps in and acknowledges this. But if I was allowed to place bets, I'd do it. Distance doesn't matter as long as it's only fiber patches that connect the two (taking the supported distances into account).

Enjoy that VPLEX of yours!
