This application claims the benefits of and priority to U.S. Provisional Patent Application Ser. No. 62/608,383 filed Dec. 20, 2017, the disclosure of which is incorporated herein by reference in its entirety.
TECHNICAL FIELDThe present disclosure relates generally to a data storage system including data storage devices, more particularly, to a system and method for providing a local management console for managing data storage devices.
BACKGROUNDHyperscale computing and new generations of cloud services and networking technologies are redefining data storage and management schemes in a datacenter. As the underlying technologies advance, the existing hardware and infrastructure of the datacenter needs to be reconfigured or scaled, or new infrastructure needs to be built to accommodate the increasing demands for compute, memory, networking, and storage.
Solid-state drives (SSDs) are rapidly becoming main storage elements of modern datacenter infrastructure quickly replacing traditional storage devices such as hard disk drives (HDDs). SSDs offer low latency, high data read/write throughput, and reliable persistent storage of user data. Non-volatile memory express (NVMe) over fabrics (NVMe-oF) is an emerging technology that allows hundreds and thousands of SSDs to be connected over a fabric network such as Ethernet, Fibre Channel, and Infiniband.
The NVMe-oF protocol enables remote direct-attached storage (rDAS) allowing a large number of NVMe SSDs to be connected to a remote host over the established fabric network. The NVMe-oF protocol may use the remote direct memory access (RDMA) to provide a reliable transport service to carry NVMe commands, data, and responses over the network. iWARP, RoCE v1, and RoCE v2 are some examples of the transport protocols that provide an RDMA service. While RDMA has been the primary motivation of enabling NVMe-oF, Fibre Channel over Ethernet (FC-oE) and Transmission Control Protocol (TCP) are/have been also enabled as newer transport protocols for the same purpose.
A traditional storage server includes an x86-based (or similar) central processing unit (CPU) that runs an operating system (OS) to provide interfaces to coupled hardware devices. For example, a server loaded with a standardized operating system (e.g., LINUX) has one or more input ports for providing interfaces to various input devices such as a keyboard and a mouse and a display port to connect a local display device such as a video graphics array (VGA) port, a display port, or a high-definition multimedia interface (HDMI) port. In addition, the server can be connected to a remote display device through a remote session to provide an interface for a service administrator to upkeep the connected hardware devices. For a local user, the interface provides configurability, usability, debug, and status of the locally connected hardware devices.
SSDs compatible with the NVMe-oF standard, eSSDs (Ethernet SSD) in short, can remove the requirement of a costly CPU by fusing networking with storage and supporting a network storage protocol. The protocol translation is handled as much in a hardware-based mechanism such as a field-programmable gate array (FPGA) that provides performance and speed while removing bottlenecks that are inherent in the conventional x86-based CPU-heavy architecture.
A storage rack in a datacenter includes a plurality of enclosures referred to as chassis, and each chassis can include a plurality of storage devices such as eSSDs. Within an eSSD chassis, a low-cost baseboard management controller (BMC) directly manages the connected eSSDs to provide a remote interface to a system administrator to configure, control and report status to a system administrator. Typically, the eSSD chassis does not have a display port for providing a display interface of the eSSDs in a specific eSSD chassis.

The present disclosure a system and method for providing a local management console (LMC) for a chassis that includes a plurality of data storage devices. An example of the data storage device is an NVMe-oF compatible solid-state drive (SSD), herein referred to as an eSSD, and the chassis including plurality of eSSDs is herein also referred to as an Ethernet chassis or an eSSD chassis. The LMC can provide various usages that are currently unavailable with a conventional eSSD chassis.
The LMC can connect to one or more eSSD chassis wiredly and wirelessly. A local administrator may physically carry the LMC in a datacenter, or the LMC may be placed at a strategic location within the datacenter. The LMC can collect data from each of the connected eSSD chassis and act on the data that collected from the eSSD chassis. The local administrator can use the LMC to monitor and query a status, and configure parameters of the eSSDs in the eSSD chassis and can even override, if necessary, and if authorized, any eSSD parameters configured by a remote system administrator (herein also referred to as a super administrator). The LMC can provide a granularity of managing eSSDs in the eSSD chassis, or collectively configuring and managing eSSDs and eSSD chassis using the collected data.
Each eSSD chassis may include a baseboard management controller (BMC). According to one embodiment, the LMC can use an NVMe management interface (NVMe-MI) for communicating with the BMC of each eSSD chassis. The LMC can persist various statistical data including performance related data of the eSSDs over a period of time for offline review and diagnostics for vendor-specific and generic datacenter details. Based on the collected data, the local administrator in possession of the LMC can send instructions to the BMC of the eSSD chassis to perform various configuration and monitoring actions for the eSSD chassis and the eSSDs in the eSSD chassis.
According to one embodiment, the LMC can securely communicate with the BMC. The LMC can not only display the collected data from eSSDs in the eSSD chassis but also securely process and provide statistical data of the eSSDs in the eSSD chassis. The LMC can show data specific to an eSSD chassis and a rack-level or datacenter-level statistical data combining data of multiple eSSD chassis to provide information of a rack, or multiple racks across the datacenter. The remote administrator can offload certain levels of datacenter management tasks to the local administrator through the LMC.
The Ethernet switch 161 provides network connectivity between the host 110 and the eSSDs 170. The Ethernet switch 161 may have large-capacity (e.g., 100 Gbps) uplinks to connect to one or more hosts. The Ethernet switch 161 also has multiple lower-capacity (e.g., 25 Gbps) downlinks to connect to the eSSDs 170. For example, the Ethernet switch 161 contains 12 uplinks of 100 Gbps and 24 or 48 downlinks of 25 Gbps. The Ethernet switch 161 may have a special configuration/management port to the BMC 162.
The BMC 162 manages the internal components of the chassis 160 including the Ethernet switch 161, the PCIe switch 163, and the eSSDs 170. The BMC 162 can support PCIe and/or system management bus (SMBus) interfaces for the system management. The BMC 162 can configure the eSSDs 170 and program the Ethernet switch 161.
Similar to server based all-flash arrays (AFAs), eSSDs 170 are housed together in a server-less enclosure (i.e., the chassis 160) that contains a bunch of eSSDs, a network switch (i.e., the Ethernet switch 161) to connect them with the outside world's hosts and the BMC 162 to manage them. The BMC 162 handles the boot and control paths to the eSSD devices. Unlike a full-fledged x86 CPU, the BMC 162 may not do all those tasks that a CPU can handle and hence does the minimal enclosure management functions. The BMC 162 does keep a health check on the connected eSSDs 170 and related hardware for connectivity, status, temperature, logs, and errors through the SMBus.
The CPU-based host 210 runs the operating system and file system 212 to employ host drivers and services to query, control, and apply the services to the eSSDs in the eSSD chassis. The BMC of the eSSD chassis 260 may not have a capability to run the operating system to provide an interface to a local administrator to provide status and other indicators of the eSSDs.
According to one embodiment, the BMC for each eSSD chassis can run a service to provide a remote interface to a local administrator and a super administrator who manage the operation of the datacenter. The service employed by the BMC can be built with minimal elements required to provide a control path to the eSSDs. The BMC may not include an x86 CPU. Instead, the BMC may be an integrated chip including limited memory and logic capable of running embedded applications and firmware code for providing the remote service and other management functions of the chassis.
Although the present examples shown in
The present system and method provides an NVMe-oF system including an LMC that provides local management for disaggregated NVMe-oF Ethernet SSD chassis (eSSD chassis or chassis in short) and the eSSDs included therein for local management in conjunction with a remote administrator. The eSSD chassis eSSD chassis provides a large number SSDs to be connected to remote initiators (e.g., the application 211 of
The present system and method provides an LMC to configure eSSDs and the chassis for connectivity setup, data protection/reduction and other features, and deployment and removal/replacement of the eSSDs. The LMC can display information at various levels including eSSD, chassis, rack, and datacenter to show serviceability messages, status, performance, etc. Legacy CPU-based servers having a CPU can run an operating system to interact with the datacenter administrator. The present data storage system does not need such CPU-based servers. The LMC can connect with the BMC for each chassis to display data to a local administrator. The LMC can work with a remote administrator to display service messages for the local administrator. The LMC can have a small screen or a grander display depending on a usage and application. The LMC can be connected to the BMC directly or wirelessly. The LMC can digest the BMC-provided data per each chassis to collect and provide chassis-level, rack level, or datacenter-level information.
The present system and method supports a remote direct attached storage (rDAS) model with better latency and IOPs performance. The BMC included in each chassis acts an agent through which the remote administrator can configure and manage the eSSDs in the chassis. The BMC can use the NVMe-MI protocol over the PCIe or SMBus interface to configure, monitor, and manage the eSSDs. The remote administrator may use SwordFish/RedFish or other proprietary communication protocols to communicate with the BMC.
Since the remote administrator is remotely connected, there is a need for local management for the eSSD chassis and other assets available in a storage rack. The LMC provides a mechanism to provide support for the local administrator who may be physically present in the same datacenter in which the storage devices (e.g., eSSDs) physically reside and are managed. A conventional model that allows communication between the BMC to the remote administrator can be expanded to support the communication between the BMC and the local administrator. The local communication between the BMC and the LMC facilitates status updates of the eSSDs to the local administrator. This can also facilitate changes to the eSSDs by the local administrator overriding previously set configurations. The present system and method enables facilitated communication between the BMC and the local administrator using various types of local management consoles, and capability to configure and change attributes and parameters of the eSSDs that are exposed to the local administrator.
The LMC provides a mechanism that can be used by the local administrator to monitor, configure, and manage a NVMe-oF Ethernet SSD chassis and a rack including multiple chassis. In the rDAS model, there can be situations where it may be desirable to have a visibility of a local administrator into the status of the eSSDs. In these situations, it would be desirable to provide configuration capability to the local administrator.
The NVMe-oF Ethernet SSDs, eSSDs in short, provides high performance disaggregated storage of data. The NVMe-oF standard is an emerging technology that allows hundreds and thousands of SSDs to be connected to the remote initiators. Such disaggregated storage needs local storage monitoring and configuration capabilities in addition to traditional administrative functions. The LMC that works with the BMC in the chassis can assist the local administrator. The LMC has a communication link to a BMC, a display unit, and a user input device such as touch screen or key pad.
The local administrator can view various vital stats, current health status, logs, and performance levels of the eSSDs. The local administrator is also capable to effect changes to the configuration of each eSSD through the BMC. An LMC may be able to communicate with other LMCs to form a hierarchy of LMCs or a form a central LMC system for the whole datacenter.
A remote administrator 364 can manage the operation of each chassis 360 via the Ethernet 350. The chassis 360 may not have a display port for connecting to a display device. Instead, the chassis 360 can connect to a local management console (LMC) 380 wiredly or wirelessly. The LMC 380 can provide a communication interface to connect to the chassis 360 and a display for displaying a status of the eSSDs 370 included in the chassis 360. For example, the display of the LMC 380 can display data specific to the chassis 360 and/or eSSDs 370 such as connectivity, input/output (I/O) activity with access requests information such as a size, bytes, I/O counts, distribution, temperature, and detailed information regarding the storage drive and network interface. According to one embodiment, the LMC 380 provides general activities of the eSSDs 370 in the form of a message, for example, an SFF-8489 type message.
According to one embodiment, the LMC 380 can provide an interface to assist an administrator (e.g., a local administrator 365 and a remote administrator 364) in upkeeping of the connected eSSDs 370. For example, the local administrator 365 can use the interface provided by the LMC 380 to configure, control, debug, and display status of the connected eSSDs 370. In one embodiment, the LMC 380 can provide visual indicators to the local administrator 365. The visual indicators may include data, messages, graphics, signs, or the like. For example, the LMC 380 may display a service light to identify a chassis and a rack or other locality-based indicators including, but not limited to, a voice call or a text message.
The LMC 380 may be connected to the chassis 360 in various ways. The BMC 362 of the chassis 360 can drive the connection to the LMC 380 through a directly wired connection such as SMbus, PCIe, and Ethernet or a wireless connection such as wireless local area network (WLAN), Wi-Fi, Bluetooth, Bluetooth Low Energy (BLE) to provide single and status information of the eSSDs 370 within the chassis 360. The LMC 380 can be connected to all chassis within a rack to show a broader rack-level view. The LMC 380 can also be connected to multiple racks within a region of a datacenter or the entire datacenter for a global datacenter-level view.
The LMC 380 may have intelligence to interpret and process the data received from the BMC 362 of the chassis 360. The BMC 362 can merely collect data collected from the eSSDs 370 and send the unprocessed data to the LMC 380.
The communication between the BMC 362 and the LMC 380 is established to be reliable and secure. In one embodiment, the BMC 362 communicates with the eSSDs 370 using the NVMe-MI protocol. The same NVMe-MI protocol can be used for communication between the BMC 362 and the LMC 380. Each LMC 380 can identify itself as a unique device through Identify, Vital Product Data (VPD), and Management data structures as supported in the NVMe-MI protocol to the BMC 362. The VPD utilizes a format defined in the IPMI Platform Management FRU Information Storage Definition. The LMC 380 can advertise its characteristics, features, capabilities, and requirements through the Identify, VPD, and Management data structures. The BMC 362 can periodically poll the LMC 380 to check if the LMC 380 needs to perform any data transfer between the LMC 380 to the BMC 362.
Examples of the data transferred from the LMC 380 to the BMC 362 include, but are not limited to, configuration commands that the LMC 380 performs on the eSSDs 370 or other components in the chassis 360. Examples of the configuration commands that the LMC 380 may set or change through the BMC 362 include, but are not limited to, configuration of a new eSSD or removal of an existing eSSD, updates to existing features for an eSSD, accessibility to an eSSD such as an IP address, an Ethernet address, and switch configuration. The LMC 380 may also instruct the BMC 362 to monitor certain parameters such performance, capacity, or remaining life for certain eSSDs 370. The LMC 380 may provide specific details to the BMC 362 regarding the signals and parameters to monitor, the monitoring frequency, etc.
Examples of the data transferred from the BMC 362 to the LMC 380 include, but are not limited to, various statistical data, status information, logs, or performance data, and the LMC 380 can display the data, generate an email and a text message, or deliver the information to the local administrator 365. The BMC 362 may push such data periodically, or the LMC 380 may pull the data when desired, for example, when the local administrator 365 clicks a button displayed on the LMC 380.
Below is an example pseudo code implemented in a logic of the BMC 362, according to one embodiment. The logic of the BMC 362 includes a data loop through eSSDs in parallel, a data push routine to the LMC 380, and a connection verification routine.
The communication channel established between the BMC 362 and the LMC 380 and between an LMC 380 and another LMC 380 is a secure channel. To establish the secure communication channel, the BMC 362 may perform an authentication check, and once the secure communication channel is established, the BMC 362 communicates with the LMC 380 for the actual data transfer. The remote administrator 364 may setup permissions and restrictions on the functionalities that are allowed or offloaded to a specific LMC 380. Such synchronization between the remote administrator 364 and the local administrator 365 is critical for the integrity of the storage management. A well-defined and agreed upon set of management policies that the local administrator 365 follows are essential for effective and reliable management of the data storage devices in the datacenter.
According to one embodiment, various parameters of the eSSDs 370 and the chassis 360 including the eSSDs 370 are monitored for local storage management. The LMC 380 can render the monitored status and other statistical data for the use by the local administrator 365. The LMC 380 may send an email or a text message, or provide a snapshot of the collected data to the local administrator 365. Examples of the parameters displayed by the LMC 380 include, but are not limited to, SSD health status, remaining life, alerts, I/O performance, network statistics, logs, vendor-defined parameters. The BMC 362 may process the raw data to generate data regarding the performance data of the eSSDs 370. The LMC 380 may only render or forward the data or the LMC 380 may further process the data that the BMC 362 provided.
According to one embodiment, the present data storage system including one or more LMCs can monitor and display parameters of the data storage devices (e.g., eSSDs) on a desirable granularity. Examples of the granularity are: per eSSD, per chassis, per rack, set of eSSDs across chassis or racks, set of chassis, the whole data center.
According to one embodiment, an LMC 380 can report to another LMC such as a central LMC 385 to broaden the scope of the storage monitoring capability. The LMC 380 and the central LMC 385 may have a different level of permissions and restrictions on functionalities to manage the chassis 360 and the eSSDs 370. Such hierarchy of the LMCs can provide a centralized local storage management scheme by providing a datacenter-level view. The local administrator 365 can zoom in to a finer granularity to see a view-per-rack or view-per-chassis as desired. Although the present example describes a single BMC-to-LMC communication, it is possible that multiple BMCs can communicate to a single LMC over a wireless communication channel.
