Abstract
Management applications (hosts) implement management operations on a storage system by passing system calls (syscalls) to a management system. In some embodiments, all management traffic is passed from one or more instances of a management application to a management daemon executing in the context of the storage system operating system. The management daemon sorts syscalls received from the management applications and implements the syscalls using one or more array control devices. The array control devices are special target devices configured on external control hosts for sending management commands to the storage system operating system and receiving information from the storage system. In some embodiments, Non-Volatile Memory express (NVMe) devices to be used as array control devices, and enable TCP connections to be used as logical array control devices. Adding multiple protocol support in the existing management software infrastructure enables users to seamlessly migrate to the new data center technologies.
