BACKGROUND
In a data center, multiple appliances are utilized to scale out and scale up compute power and storage capacities. Networking appliances, for example, network switches and network routers are used to connect servers to each other and also to multiple storage appliances. Large numbers of servers are used for computing, which therefore require a large number of network switches, for example, Ethernet switches, fibre channel switches, etc., to connect servers to each other and to storage appliances. Storage appliances such as disk storage arrays and tape libraries are used in a data center to provide a large storage space for user data and for data backup. Due to the servers, storage appliances, and network appliances, the challenges faced in data centers are, for example, large space requirements, high energy consumption by different appliances, high energy consumption to maintain the operational temperature of the appliances, high heat emission, numerous applications required to maintain different types of server appliances, storage appliances, and network appliances, a team of various skilled professionals required to maintain the data center, high capital, substantial operational expenses, etc.
The compute power, storage and networking of servers keep growing in data centers to improve and boost application performance of the server appliances. To facilitate high performance of application servers, data centers add superior server processors, fast networking technologies, and multiple redundant storage elements. However, the server processors, fast networking technologies, and storage elements are not optimally used due to architectural limitations of the data centers. For example, a conventional architecture of servers, network appliances, and data storage arrays depends on multiple software layers from a host operating system to input and output interface controllers. Such an architecture adds high latency to input/output (I/O) throughput.
Cloud and parallel data processing and storage have become paramount as the need for data storage, data processing, and intelligent storage has increased. Numerous techniques and solutions available in the field of cloud data processing and parallel data processing rely on efficient hardware and software solutions. Data centers have resorted to private, public and/or hybrid cloud solutions as incorporating computing power within or away from storage is not a choice anymore. Furthermore, the basic idea behind a cloud infrastructure is to grow with the use of computing and storage power. However, the dynamic growth of data processing and storage within the cloud infrastructure poses challenges to the current infrastructure. The cloud industry or data centers typically fine-tune their solutions and technologies associated with servers, network appliances, and storage to cater to a constant demand of exponential data growth for efficiency. Ensuring efficiency of data processing and growth in computing requires large investments in terms of capital, power, cooling techniques, etc. Therefore, an Infrastructure as a Service (IaaS) provider spends more time and money to obtain appropriate solutions for an offered infrastructure.
A conventional architecture of a server, a network appliance, or a data storage array utilizes a host bus adapter (HBA) containing a System on Chip (SoC) to handle input and output of data flow on a respective system board. The SoC is a set of hardware components, for example, a central processing unit (CPU), a memory controller, a system bus controller, and a peripheral interconnect bus controller that enables the host bus adapter to run software that manages the data flow through the host bus adapter and target devices, for example, disk drives, network ports, etc. This SoC runs software for data communication to and from a target device, for example, a data storage device, or a data storage appliance, or a network server, or a network appliance. The combination of hardware and software for data access and communication reduces data throughput of the overall system. Furthermore, there are additional issues in conventional architecture based appliances that hinder the performance of the system, for example, underutilization of hardware appliances, low adaptability to dynamic growth, low performance, interoperability issues between appliances manufactured by different vendors, a high total cost of ownership that involves large space requirements, high energy consumption, requirements for skilled maintenance teams, etc.
In a conventional architecture of a server, network switch, network router and data storage array, connecting element controllers, for example, small computer system interfaces, advanced technology attachments, serial attached small computer system interfaces, serial advanced technology attachments, fibre channel controllers, Ethernet controllers, etc., are mounted on system boards of servers, network switches, network routers, and data storage arrays as host bus adapters or line cards. The host bus adapters contain specific hardware to manage connecting ports to target devices, for example, hard disk drives, network switches, network routers, and other servers. Each host bus adapter also contains a System on Chip (SoC). Typically, a data center houses hundreds and thousands of servers, network switches, network routers, and storage arrays that are built on the above mentioned conventional architecture. SoC hardware and software on the SoC introduces additional layers that cause additional latency to the data flow, increases the energy consumption, and increases heat emission. As the new era of data centers emerge, the work load on the servers, the network switches, the network routers, and the storage arrays suffers due to the above mentioned conventional architecture that utilizes multiple hardware and software layers. To improve the architecture to be future ready and to withstand and take more work load, there is a need for reducing the hardware and software layers, for incorporating multiple hardware components and associated software on one functional plane, that is, on a system board, and for developing a specialized software without hindering the software implementation of existing application servers.
Hence, there is a long felt but unresolved need for a unified converged network, storage and compute system that incorporates the functionalities of a network switch, a network router, a network interface card, a storage array, and a compute functionality of a server into a single physical server for expanding the functionality of the physical server and the connectivity of the physical server to other physical servers in a data center. Moreover, there is a need for a unified converged network, storage and compute system comprising interface components that are free of the System on Chip (SoC) to allow direct access to storage devices and a network and to reduce latency, energy consumption, and heat emission. Furthermore, there is a need for a unified converged network, storage and compute system that reduces hardware and software layers, incorporates multiple hardware components and associated software on a single system board, and comprises a specialized software that does not hinder the software implementation of existing application servers.

The unified converged network, storage and compute system (UCNSCS) disclosed herein addresses the above stated need for incorporating functionalities of a network switch, a network router, a network interface card, a storage array, and a compute functionality of a server into a single platform, thereby expanding the functionality of the UCNSCS and the connectivity of the UCNSCS to other UCNSCSs in a data center. The UCNSCS disclosed herein comprises interface components that are free of a System on Chip (SoC) to allow direct access to storage devices and a network and to reduce latency, energy consumption, and heat emission. Furthermore, the UCNSCS disclosed herein reduces hardware and software layers, incorporates multiple hardware components and associated software on a single system board, and comprises specialized software that does not hinder software implementation of existing application servers.
In an embodiment, the unified converged network, storage and compute system (UCNSCS) is configured in a rack unit chassis of a configurable size, for example, a two rack unit chassis, a three rack unit chassis, a four rack unit chassis, etc. The UCNSCS disclosed herein comprises a system board, a storage interface component free of a System on Chip (SoC), a network interface component free of the SoC, and a unified converged network, storage and compute application (UCNSCA) executable by at least one processor. The storage interface component is operably connected to the system board via system interconnect bus connectors. The storage interface component connects an array of storage devices, for example, disk drives, solid state drives, solid state hybrid drives, etc., to the system board. The storage devices are connected on the local UCNSCS via the storage interface component. The storage interface component comprises disk interface connectors, a system interconnect bus switch, and the system interconnect bus connectors. The disk interface connectors are configured on a first section, for example, a front section of the storage interface component to connect to the array of storage devices. The system interconnect bus switch is configured on a second section, for example, a rear section of the storage interface component to connect the array of storage devices to the system board. The system interconnect bus connectors are configured on the second section, for example, the rear section of the storage interface component to connect to the system board. The network interface component is operably connected to the system board via system interconnect bus connectors. In an embodiment, the network interface component is a converged network switch and router adapter free of the SoC. In another embodiment, the network interface component is a network interface card free of the SoC. The network interface component is configured to form a network of UCNSCSs and/or connect to a network.
The unified converged network, storage and compute application (UCNSCA) controls and manages operations of the unified converged network, storage and compute system (UCNSCS) and expands functionality of the UCNSCS to operate as a converged network switch, network router, and storage array. The UCNSCA is a compute module that comprises a storage module and a network module. In an embodiment, the UCNSCA is configured as a hypervisor that hosts virtual machines and incorporates the storage module and the network module therewithin, thereby allowing direct access to storage devices and a network respectively. The UCNSCA configured as a hypervisor acts as a hardware abstraction layer by incorporating software and firmware functions therewithin. In another embodiment, the UCNSCA is configured as a virtual machine operating on a hypervisor and incorporates the storage module and the network module therewithin. The storage module of the UCNSCA is a software module that interacts with the storage interface component via a system interconnect bus to configure the storage interface component, monitor data flow between the storage interface component, the system board, and the array of storage devices, access data stored in the array of storage devices connected to the storage interface component, and access the data stored in storage devices of other UCNSCSs that are connected together in a computer cluster, for example, over an Ethernet network. The network module of the UCNSCA is a software module that interacts with the network interface component via a system interconnect bus to configure the network interface component, monitor data flow through the network interface component, and perform connections to the network, network switching functions, and network router functions.
In the unified converged network, storage and compute system (UCNSCS) disclosed herein, hardware components, for example, the storage interface component and the network interface component are converged onto one functional plane, that is, onto the system board, and specialized software, that is, the unified converged network, storage and compute application (UCNSCA) is developed without hindering software implementation of existing application servers. The UCNSCA disclosed herein performs functions to manage data flow through hardware boards, for example, the system board, the system interconnect bus switch board, etc., and also to manage the hardware. The UCNSCA configured as a hypervisor enables the UCNSCS to run multiple virtual machines that, in turn, run existing application servers as a conventional server.
Moreover, the unified converged network, storage and compute system (UCNSCS) does not require an external network switch or an external network router to interconnect other systems, since the UCNSCS contains the network interface component to implement network switch and network router functionalities within. Furthermore, the storage module of the unified converged network, storage and compute application (UCNSCA) pools storage devices of other systems via a network and creates a logical disk, thereby precluding the need for an external data storage array. The UCNSCS comprising the storage module and the network module within the UCNSCA reduces latency in accessing data, reduces the cost of the UCNSCS, reduces a total cost of ownership (TCO) by converging hardware components, reduces energy consumption, and boosts software performance with high performance server central processing units (CPUs), memory and software architecture. Furthermore, updating software features results in reduced system downtime in a data center.

FIG. 10 exemplarily illustrates internal components of the storage module 108 of the unified converged network, storage and compute application (UCNSCA) 107 or 112 exemplarily illustrated in FIGS. 3-4. In an embodiment as exemplarily illustrated in FIG. 10, the storage module 108 comprises a storage firmware driver 108e, a peripheral driver 108d, a physical disk handler 108c, a volume manager 108b, and a storage control manager 108a. The storage firmware driver 108e identifies and configures the storage interface component 105 exemplarily illustrated in FIGS. 3-4, FIG. 5, and FIG. 7. The storage firmware driver 108e then registers the storage interface component 105 with the system interconnect bus 111 exemplarily illustrated in FIGS. 3-4, FIG. 5, and FIG. 7. The storage firmware driver 108e configures the storage interface component 105 and monitors data flow between the storage interface component 105, the system board 104, and the storage devices 102 exemplarily illustrated in FIGS. 3-4. The storage firmware driver 108e recognises and passes the attached storage devices 102 to the peripheral driver 108d. The peripheral driver 108d recognises the storage devices 102 by their protocol and maintains the storage devices 102 in an enumerated list. The peripheral driver 108d communicates with each storage device 102 by a respective protocol, for example, a small computer system interface protocol, an advanced technology attachment protocol, etc., of each storage device 102.
The physical disk handler 108c performs physical disk abstraction and keeps track of storage devices 102 such as physical disks that are either directly attached or attached over a network to the unified converged network, storage and compute system (UCNSCS) 100a exemplarily illustrated in FIG. 3, or 100b exemplarily illustrated in FIG. 4. The physical disk handler 108c also abstracts interactions between the attached physical disks by acting as an advanced technology attachment (ATA), a small computer system interface (SCSI), and an Ethernet protocol agnostic layer. The volume manager 108b accumulates the physical disks tracked by the physical disk handler 108c to form a logical disk. As used herein, “logical disk” refers to a virtual device that provides an area of usable storage capacity on one or more storage devices 102 in the UCNSCS 100a or 100b. The logical disk is also referred to as a logical volume or a virtual disk. The storage control manager 108a presents the logical disk as a physical storage device 102 to a consumer. In the implementation of the unified converged network, storage and compute application (UCNSCA) 107 as a hypervisor exemplarily illustrated in FIG. 3, logical disks are provisioned to the UCNSCA 107 as a local disk. In the implementation of the unified converged network, storage and compute application (UCNSCA) 112 as a virtual machine exemplarily illustrated in FIG. 4, the logical disks are provisioned over the network using an Ethernet technology.
FIG. 11 exemplarily illustrates internal components of the network module 109 of the unified converged network, storage and compute application (UCNSCA) 107 or 112 exemplarily illustrated in FIGS. 3-4.

The network firmware driver 109e identifies and configures the network interface component 106, that is, the converged network switch and router adapter (CNSRA) 114 exemplarily illustrated in FIG. 6, or the network interface card 121 exemplarily illustrated in FIG. 8. The network firmware driver 109e then registers the network interface component 106 with the system interconnect bus 111 exemplarily illustrated in FIGS. 3-4, FIG. 5, and FIG. 7. The network firmware driver 109e configures the network interface component 106 and monitors data flow between the system board 104, the network interface component 106, and the network ports 103 exemplarily illustrated in FIG. 5 and FIG. 7. The layer 2 109d configures and maintains a flow table for a flow of network packets. Based on a destination address of a received network packet, the layer 2 109d redirects the flow of network packets to respective network interfaces as set in the flow table. The layer 3 109c configures and maintains a routing table for the flow of network packets. The layer 3 109c also maintains a virtual extensible local area network (VXLAN) domain. The network flow controller 109b recognises flow instructions from the network control manager 109a, for example, based on the OpenFlowTM protocol versions 1.0, 1.1, and 1.2 of the Open Networking Foundation. The network flow controller 109b is an interpreter of OpenflowTM based commands to the native flow instructions. The network control manager 109a configures the network flow controller 109b to setup the flow table for the layer 2 109d and the layer 3 109c. The network control manager 109a provides an interface for interacting with the network firmware driver 109e to configure the network interface component 106.

The UCNSCA 107 as a hypervisor comprises the storage module 108 and a hypervisor storage provision module 127. An array of storage devices 102 are connected to the storage interface component 105 exemplarily illustrated in FIG. 3. Data read from the storage devices 102 is passed to the storage module 108 via the storage interface component 105. The storage module 108 virtualizes the storage devices 102 that are connected through the storage interface component 105. The storage module 108 pools the storage devices 102 that are local to a server appliance and also pools the storage devices that are connected over a network and creates a logical disk. The storage module 108 exposes the logical disk to the hypervisor storage provision module 127. The hypervisor storage provision module 127 provisions the logical disk to a guest virtual machine 128.
FIG. 13 exemplarily illustrates a flowchart showing operation of the unified converged network, storage and compute application (UCNSCA) 107 as a hypervisor exemplarily illustrated in FIG. 3 and FIG. 12. A guest virtual machine 128 that has a logical disk provisioned by the hypervisor storage provision module 127 of the UCNSCA 107 writes or reads data from a storage device connected to the unified converged network, storage and compute system (UCNSCS) 100a exemplarily illustrated in FIG. 3. The hypervisor storage provision module 127 receives an input/output (I/O) request from the guest virtual machine 128 and forwards the I/O request to the storage module 108. The storage module 108 checks 1301 whether the I/O request is for a local storage device 102 or a network storage device, that is, a storage device connected to the UCNSCS 100a over a network. If the I/O request is for a local storage device 102, the storage module 108 retains and handles the I/O request, in communication with the storage interface component 105. If the I/O request is for a network storage device, the storage module 108 forwards the I/O request to the network module 109. The network module 109 forwards the I/O request, via the network interface component 106, to a UCNSCA of another UCNSCS in the network, which is connected to the network storage device directly.
FIG. 14 exemplarily illustrates an implementation of the unified converged network, storage and compute application (UCNSCA) 112 as a virtual machine. The array of storage devices 102 are connected to the storage interface component 105 exemplarily illustrated in FIG. 4. The storage interface component 105 passes the data read from the storage devices 102 to the storage module 108. The storage module 108 virtualizes the storage devices 102 that are connected through the storage interface component 105. The storage module 108 pools the storage devices 102 that are local to the server appliance and also the storage devices that are connected over a network and creates a logical disk. The storage module 108 exposes the logical disk to a guest virtual machine 128 either on the same server appliance or another server appliance in the network. The storage module 108 provisions the logical disk as a network drive to the guest virtual machine 128.
FIG. 15 exemplarily illustrates a flowchart showing operation of the unified converged network, storage and compute application (UCNSCA) 112 as a virtual machine exemplarily illustrated in FIG. 4 and FIG. 14. A guest virtual machine 128 that has a logical disk provisioned by the UCNSCA 112 writes or reads data from a storage device connected to the unified converged network, storage and compute system (UCNSCS) 100b exemplarily illustrated in FIG. 4. The storage module 108 of the UCNSCA 112 receives an input/output (I/O) request from the guest virtual machine 128 and checks 1501 whether the I/O request is for a local storage device 102 or a network storage device. If the I/O request is for a local storage device 102, the storage module 108 retains and handles the I/O request, in communication with the storage interface component 105. If the I/O request is for a network storage device, the storage module 108 forwards the I/O request to the network module 109. The network module 109 forwards the I/O request, via the network interface component 106, to a UCNSCA of another UCNSCS in the network, which is connected to the network storage device directly.

The UCNSCA 107 enables the storage devices 102 of the UCNSCSs 100a connected in a computer cluster, for example, through an Ethernet network to provide logical volumes to other UCNSCSs 100a for implementing storage virtualization in a data center. A logical volume is an allocation of storage that is less than or more than one physical drive. The UCNSCSs 100a are connected to each other in the computer cluster, for example, using an Ethernet cable 1601 connected to their respective network ports 103 exemplarily illustrated in FIG. 2B. The UCNSCA 107 allows collaboration of storage capacity of the storage devices 102 of each UCNSCS 100a in the computer cluster into a single logical disk to provide logical volumes to each UCNSCS 100a in the computer cluster.

The UCNSCA 112 enables storage devices 102 of the UCNSCSs 100b connected in a computer cluster, for example, through an Ethernet network to provide logical volumes to other UCNSCSs 100b for implementing storage virtualization in a data center. The UCNSCA 112 allows collaboration of storage capacity of the storage devices 102 of each UCNSCS 100b in the computer cluster into a single logical disk to provide logical volumes to each UCNSCS 100b in the computer cluster. FIG. 16 and FIG. 18 exemplarily illustrate the cluster of UCNSCSs 100a and 100b respectively, irrespective of the UCNSCA 107 or 112 being a hypervisor or a virtual machine exemplarily illustrated in FIG. 3-4.

Consider an example where there are N machines, namely, machine 1 1701, machine 2 1702, . . . , and machine N 1703. Each of the machines has four storage devices, for example, P11, P12, P13, and P14 102a, P21, P22, P23, and P24 102b, and PN1, PN2, PN3, and PN4 102c connected locally. The storage module 108 and the network module 109 running in the UCNSCA 112 functioning as a virtual machine pools the four storage devices 102a, 102b, and 102c via a network and creates a logical disk 1704. The UCNSCA 112 as a virtual machine that hosts the storage module 108 and the network module 109 therewithin thereby facilitates creation, configuration, and management of a data center infrastructure.
