QLogic SB3810-08A8 or Brocade BR320?

Question

Iron

Hello colleagues!
There is a need to build a small cluster of two storage systems and three virtualization servers.
Now we are faced with the choice of an FC-Switch, the contenders are in the title.
I must say right away that 8 ports for the eyes, more than eight will not be for sure.
Here's what vendors have to say about it:

Latency for Brocade is 0.7 ms, for QLogic it is 0.2 ms.
QLogic fully supports NPIV, Brocade only in gateway (not switch) mode.
QLogic supports transparent routing.

What confuses me? That with the best characteristics of QLogic costs one and a half pieces cheaper.
Please help me make a choice.
UPD. If this is important, then two switches are planned, as in the picture

Answer 1

I don’t know the prices, but there may be a difference due to the delivery kit, for example, when selling switches, a brocade is often included in the kit:
Software Included - Brocade Advanced Zoning, Brocade Fabric Watch, Brocade Advanced Performance Monitoring, Brocade Extended Fabrics, Brocade Advanced Web Tools, Brocade Data Center Fabric Manager, Brocade Adaptive Networking

Answer 2

Definitely QLogic . It’s just that it’s more popular and you can even steal a BU at a low price.
Well, another point, think over the scheme better. As I understand it, the second storage system will be like an active copy in case the first storage system fails? Then you must also have stackable switches, etc., otherwise this whole scheme does not make sense at all.
