SF HA LUN limits

I’m answering a RFP over here in Brazil, and is about SF HA. The RFP asks for this: “1200 logical volumes support with 450TB of total data, per cluster subsystem”. Does SFHA support this limit?

    There is no logical volume limit set by SFHA. It follows OS device/target limit. For example, on Linux, the default OS limit is 256, to increase, you just need to change the OS configuration file. Regarding total volume, SFHA supports some EB of data per system, as long as OS supports it.

    Support wise shouldn't be an issue but thinking from cluster design, configuring these many volumes in one cluster subsystem would definitely introduce delays in failovers ..

    Cluster/groups design should be done in this case with good planning
