A computer-implemented method for load-balancing client input/output (I/O) requests in a clustered storage system may include receiving a request by a first node of a clustered storage system from a client to initiate a session between the client and the first node. The request may specify a multi-channel communication session. In response to receiving the request, an Internet Protocol (IP) address of the first and at least a second node may be transmitted to the client. The multi-channel communication session may be established between the client and the first and second nodes in which the client communicates with the first node using a first communication channel and communicates with the second node using a second communication channel. The first node may transmit to the second node session data determined at the first node. The second node may transmit to the first node session data determined at the second node.

Load-balancing input/output requests in clustered storage systems

A computer-implemented method is provided in one general embodiment for concurrent file and object protocol access. The method includes receiving a notification that indicates storage of an object by an object-based client, and creating a clone of the object. Also, the method includes providing a file-based client access to the clone of the object. Further, the method includes, after the file-based client has finished modifying the clone of the object, replacing the object with an updated object based on the modified clone of the object. The file-based client is provided access to the modified clone of the updated object. After the file-based client has finished modifying the modified clone of the updated object, the updated object is replaced with an additional object based on the modification to the modified clone of the updated object.

Concurrent file and object protocol access using space-efficient cloning

An aspect includes a method for in-band management of a network attached storage environment. A client is connected via a standard network attached storage protocol to a network attached storage system using existing authorization and authentication procedures. Advanced management functions are exposed to the client via a special file system structure over the standard network attached storage protocol. The client uses existing standard network attached storage protocol functions on the special file system structure to retrieve and to invoke the advanced management functions. Result data are returned to the client using a feedback channel and the standard network attached storage protocol.

In-band management of a network attached storage environment

In a data management system, examination of first data for malicious content by a malicious content scanner is initiated in response to a request to write first data to a data storage device. In response to the examination revealing no malicious content in the first data, the first data, a first signature representative of a version of the malicious content scanner at a time of the examination of the first data, and second data linking the first signature to the first data as read-only data are written to the data storage device.

Data management of potentially malicious content

A computer-implemented method is provided for concurrent file and object protocol access. The method includes receiving a notification that indicates storage of an object by an object-based client, and creating a clone of the object. Also, the method includes providing a file-based client access to the clone of the object. Further, the method includes returning, in response to one or more read requests for the object received from one or more object-based clients while the file-based client modifies the clone of the object, the object to the one or more object-based clients. Moreover, the method includes, after the file-based client has finished modifying the clone of the object, replacing the object with an updated object based on the modified clone of the object.
