US 2019/0296925 A1 · UPDATING DATA OBJECTS ON A SYSTEM

Abstract

A computer system includes a first server including a first data management module and a second server including a second data management module, and a first and second storage controller. The first and second storage controllers are interconnected by a network configured for reliable data multicasting. The computer system further includes a cross system manager for controlling one or more core storage functions on each of the first and second storage controllers. The computer system further includes computer program instructions to, responsive to a core storage function triggered by the cross system manager: Create a multicast group for each of the first server and the second server in the network, wherein the multicast group is created by a reliable multicast mechanism, and Multicast data write operations of each of the first server and the second server to the first storage controller and the second storage controller of the multicast group.

Dependent claims

A computer-implemented method, comprising:

identifying, by one or more processors, a request directed to a first server to perform a core storage function for a first data object stored on a first storage device, wherein the core storage function is at least one of:
(i) real-time replication, (ii) real-time mirroring, or (iii) real-time migration;
generating, by one or more processors, in response to identifying the request to perform the core storage function, a multicast group that includes at least:
(i) the first server, (ii) a first storage controller located on the first storage device, (iii) a second server and (iv) a second storage controller located on a second storage device;
and
multicasting, by one or more processors, one or more data write operations associated with the core storage function to:
(i) the first storage controller, (ii) the second server and (iii) the second storage controller included in the multicast group.

4 more elements

A computer program product, the computer program product comprising one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising instructions to:

identify a request directed to a first server to perform a core storage function for a first data object stored on a first storage device, wherein the core storage function is at least one of:
(i) real-time replication, (ii) real-time mirroring, or (iii) real-time migration;
generate, in response to identifying the request to perform the core storage function, a multicast group that includes at least:
(i) the first server, (ii) a first storage controller located on the first storage device, (iii) a second server and (iv) a second storage controller located on a second storage device;
and
multicast one or more data write operations associated with the core storage function to:
(i) the first storage controller, (ii) the second server and (iii) the second storage controller included in the multicast group.

4 more elements

A computer system, the computer system comprising:

one or more computer processors;
one or more computer readable storage media;
computer program instructions;
the computer program instructions being stored on the one or more computer readable storage media for execution by the one or more computer processors;
and
the computer program instructions comprising instructions to:
identify a request directed to a first server to perform a core storage function for a first data object stored on a first storage device, wherein the core storage function is at least one of:
(i) real-time replication, (ii) real-time mirroring, or (iii) real-time migration;
generate, in response to identifying the request to perform the core storage function, a multicast group that includes at least:
(i) the first server, (ii) a first storage controller located on the first storage device, (iii) a second server and (iv) a second storage controller located on a second storage device;
and
multicast one or more data write operations associated with the core storage function to:
(i) the first storage controller, (ii) the second server and (iii) the second storage controller included in the multicast group.
