[0020] Referring to FIG. 2, in one example, a memory device 225 stores a set of program modules. In one embodiment of the present invention, a system for implementing optimized data replication across cloud storage nodes comprises a cluster of computer system devices. A processor 205 among the plurality of processor is comprised in a computer system device of the cluster of computer system devices. The processor 205 executes the set of program modules.

[0023] FIG. 3 is a flowchart of a computer implemented method 300 of implementing optimized data replication across cloud storage nodes in accordance with various embodiments of the invention. The method 300 is incorporated in an environment. The environment comprises a first computer system device, a second computer system device and a third computer system device. In one example, the first computer system device, the second computer system device, and the third computer system device are connected as a computer cluster. The first computer system device, the second computer system device, and the third computer system device are at least one of a laptop, a personal computer, a server, a smart phone, a network hardware device, and a smart television. The network hardware device is at least one of a gateway, a router, a network bridge, a modem, a wireless access point, and a network switch. In another example, the first computer system device, the second computer system device, and the third computer system device are gateways to at least one of a wide area network, a local area network, and internet. The first computer system device, the second computer system device, and the third computer system device are connected via a network. The network is at least one of a mobile network, a wide area network, a local area network, and internet. The first computer system device comprises a first memory device and a first processor. The second computer system device comprises a second memory device, and the second processor. The third computer system device comprises the third processor. In one embodiment of the present invention, the computer cluster comprising the first computer system device, the second computer system device, and the third computer system device hosts a system for patching software in a target computer system device. In one example, the target computer system device is at least one of the first computer system device, the second computer system device, and the third computer system device. At least one of the first memory device and the second memory device stores a set of program modules. The method 300 commences at step 305.

[0024] At step 310, each of the first memory device and the second memory device stores a set of program modules comprising an input module, and a data transfer module. At least one processor among the first processor, the second processor, and the third processor executes the set of program modules.

[0025] At step 315, an input module, executed by the processor receives via an input module, a first instruction to add a first computer system device to the cluster, wherein the first computer system device comprises a first memory device.

[0026] At step 320, a data transfer module executed by the processor copies data in at least one memory device in the cluster of computer system devices, to the first memory device, based on number of computer system devices in the cluster being lesser than a predefined number.

[0027] The method 300 ends at step 325.

[0028] In one example, FIGS. 4, 5 and 6 illustrate a system and method that automatically determines and implements optimized data replication across cloud storage nodes. Such system and method allows for the optimization of data replication across cloud data storage nodes, whether such system is comprised of one, two, or three or more computer storage nodes. The CLOUDSEED™ system automatically recognizes when a new node is added to the storage cluster.

[0029] Such optimization is accomplished as each node initially replicates data on itself when the cluster is deemed of insufficient size. When a node is added, as is the case when a single node cluster becomes a two node cluster, data is replicated as between the node, which data is then self-replicated internally to the node. When a third node is added, data is replicated to the third node.

[0030] Referring now specifically to FIG. 4, a schematic diagram of a one node system 400 comprising a computer storage node 410 is shown. Computer storage node 410 has two storage disks 420 and 430. Such is the case because when a storage cluster is first created as a single storage node, the minimum number of disks to automatically create the initial storage cluster redundancy is two, in order to internally mirror the disks in order to provide some amount of optimal redundancy of the data. It is to be understood, however, that the optimal mirror configuration of a single node is based upon the number of available disks. Accordingly, in computer storage node 410 of cluster storage node 400, data is replicated as between storage disks 420 and 430.

[0031] At some point in time, additional storage nodes are likely to be added to the cluster. Accordingly, in step 4000, a storage node is added to the cloud cluster. Step 4000 is the same in each of FIGS. 4, 5 and 6 as a storage node may be added to the system at any time. CLOUDSEED™ either directs the storage nodes to select two other nodes for data replication, or such nodes are capable of random selection.

[0032] Referring now specifically to FIG. 5, a schematic diagram of a two node system 500 comprising computer storage nodes 510 and 540 is shown. Computer storage node 510 has two storage disks 520 and 530, while computer storage node 540 also has two storage disks 550 and 560. Like the single node 410 in the one node system 400, data is replicated as between the disks internal to the node. In other words data on storage disk 520 is replicated on storage disk 530. Additionally, however, data from computer storage node 501 is replicated to computer storage node 540, and vice versa for redundancy. This is because when the second node joins the cluster as in step 4000, the disks are still mirrored internally because the minimum number of nodes to reach a desired replication level of three, is three.

[0033] Referring now specifically to FIG. 6, a schematic diagram of a three or more node system 600 comprising computer storage nodes 610, 640 and 670 is shown. Computer storage node 610 has two storage disks 620 and 630. Likewise, the other computer storage nodes 640 and 670 each have two storage disks 650, 660, 680 and 690, respectively as show in the figure. Here however, when the third node joins the cluster, each node is treated as a single unit, as redundancy is guaranteed with the other nodes in the cluster. At the same time, the mirror configuration is broken apart on the first two nodes and all disks function as single units.
