Exerience Summary in NetApp
Group:EPS
CIFS Protocol: CIFS (Common Internet File System) is a network protocol that performs file sharing and other miscellaneous communication over a network. NetApp maintains its own home-grown CIFS implementation developed by the Core Protocols Group.
Modules Worked On :
CIFS Core Command processing: This module deals with getting network packets from network layer
And converting it into corresponding commands and processing of the CIFS commands .This layer is
Responsible for managing internal memory pools for CIFS sub system .This layer deals with locking
File system interaction etc.This layer deals with Domain controller, ldap servers etc for authentication.
This module is also responsible for holding all in memory data structures for sessions, trees, opened
Files etc.
Quota: CIFS supports quotas that limit the amount of disk space used by a user (Unix or Windows) or a group (Unix), within a volume and a qtree. Quota subsystem is implemented as different threads which
Continuously monitors the usage of users in the volume.NetApp quota is supported on volumes,groups etc
and SMB calls for quota is supported .
Vscan: is the filer's anti-virus feature. VScan provides "on-access" protection for CIFS users. VScan does this by making use of an off-filer server which specializes in virus detection. NetApp provies rpc
Interfaces for the external interfaces to scan files before being written to active file system .This module
Extensively uses message queues for communicating with external vscan servers.
Responsibilities:
Understanding of entire product and functionality of each subsystem
Leading the team and ramping up of new members in team.
Involved in feasibility of feature implementation, part of reviews and audits.
Maintaining the various CIFS module codes and solving the Bugs related to it.
