величина LUN в vmware

BSD

Случайный прохожий
Всем привет! Какой размер LUN поддерживает vsphere 6.5 ? Какой оптимальный размер LUN делать под виртуальные машины и инфраструктурные сервисы - серверы? Есть ли вообще какие либо рекомендации по нарезке лунов?

SRIOV
SR-IOV Number of virtual functions per host


1024
SR-IOV supports up to 43 virtual functions on supported Intel NICs and up to 64 virtual functions on supported Emulex NICs. The actual number of virtual functions available for passthrough depends on the number of interrupt vectors required by each of them and on the hardware configuration of the host. Each ESXi host has a limited number of interrupt vectors. When the host boots, devices on the host such as storage controllers, physical network adapters, and USB controllers consume a subset of the total number of vectors. Depending upon the number of vectors these devices consume, the maximum number of potentially supported VFs could be reduced.
