Abstract: A method is used in enhancing memory buffering by using secondary storage. A buffer cache pool is supplemented with a secondary storage. A portion of a volatile memory of a data storage system is reserved as the buffer cache pool. The buffer cache pool includes a set of buffer cache objects for storing file system data and metadata. The secondary storage includes a set of data blocks. A first buffer cache object of the set of buffer cache objects is aged out by copying contents of the buffer cache object to a data block of the secondary storage. Contents of the first buffer cache object are retrieved from the secondary storage by copying contents of the data block of the secondary storage to a second buffer cache object of the set of buffer cache objects of the buffer cache pool.

Abstract: A process for selecting for analysis data units from multiple threads of traffic through a single data switch is provided. The process includes capturing all data units of one thread of traffic when said thread is selected by a system administrator, encapsulating data units matching first criteria with identification and forwarding information, and triggering on said captured data units according to second criteria selectable during said process. The process further includes filtering said captured data units according to third criteria selectable during said process and forwarding said filtered data units to a data unit analyzer.
