Dell Technologies Kinetic Infrastructure: On the Path to Fully Composable Infrastructure

first_imgCo-Authors: Jon Hass, Senior Distinguished Engineer, Server Infrastructure Solutions, Office of CTOSudhir Shetty, Distinguished Engineer, Server Infrastructure Solutions, Systems ManagementWhere we are on the pathOver the last several years, we have written about composable infrastructure and our vision for delivering full composability. A few samples of these writings can be found here and here. We thought now would be a good time to give an update on some concrete steps we have taken on the road for delivering our vision.Kinetic Infrastructure is the term we use to embody both our composable architecture vision and the real embodiments of technology we deliver on the way. Gartner recently released a report, “Understanding the Hype, Hope and Reality of Composable Infrastructure,” commenting on the industry state of composable infrastructure. In their report, Gartner lists many of the customer benefits of composable infrastructure. Their list, which we believe, matches closely to kinetic infrastructure benefits of which we have previously blogged, includes increased efficiency in resource utilization, increased flexibility in server configurations, and enabling hardware as a service capability.Gartner’s report also lists several items that need to be addressed to realize the full potential of composability. We believe two of these items are the need for additional management software for automation and the need for standard APIs.To address the need for standard APIs for composability, kinetic architecture is utilizing the mechanisms of DMTF Redfish and the principles described in the Redfish Composability White Paper. Dell Technologies have been leaders in the development and adoption of the Redfish standard and our last two generations of servers have enabled the Redfish APIs for server management. We believe that Redfish’s RESTful API is the best mechanism for allowing the interaction between higher level workload orchestration software layers, like VMware Cloud Foundation™, and composable hardware infrastructure. Through tight integration with orchestration layers, we can address the need for automation of the composable infrastructure management.The path to delivering the kinetic architecture journey: MX7000 and VMware Cloud Foundation In late 2019, Dell Technologies and VMware released composability integration between VMware Cloud Foundation and Dell EMC PowerEdge MX. VMWare Cloud Foundation (VCF) is an integrated software stack that delivers a faster path to a true integrated hybrid cloud. It automates the deployment and lifecycle management of a software-defined data center on standardized hyperconverged architecture and offers a consistent operational model based on well-known vSphere and vSAN tools and processes.PowerEdge MX platform provides a kinetic infrastructure of compute, storage and networking resources that can grow with customer workload demands. A single PowerEdge MX7000 chassis has 8-slots that can be used for compute sleds or storage sleds. A storage sled has 16 SAS drives each of which can be assigned to a compute sled. In a multi-chassis group, there can be up-to 20 chassis that are managed from the lead chassis.The Management Module embedded in the chassis hosts the Redfish Composition Service that permits a client to discover the available resources within the platform, understand the assignment constraints and perform the assignment of resources to compose a server. This functionality is available as soon as the hardware is brought online without requiring any additional software layer to be installed, which simplifies and minimizes the overall deployment and setup time for customers who are deploying VMware Cloud Foundation.Figure 1 VMware Cloud Foundation/MX integrationThe MX7000 Redfish Composition Service has 3 key constructs.Resource Blocks -the building blocks of hardware resources that can be composed by an external client to create a full-fledged computer system.Resource Zones – are used to represent the constraints to the client on what resource blocks can be composed together. So, resources within the same resource zone can be composed together.Composition Requests –The client can evaluate the workload or user request for a computer system and evaluate the zoning and block information to create a composition request. The client can a) add/remove resource blocks to an existing computer system or b) create a composition request of the desired computer system.The PowerEdge MX firmware supports resource block types of Computer System and Storage and add/remove resource block requests.VMware Cloud Foundation supports the notion of composable infrastructure by interfacing with a Redfish end-point that supports the Redfish composition service. It provides a flexible interface that permits the user to define the type of computer system desired. The user can filter for the type of computer system by specifying the range of resource values (e.g. CPU cores, CPU speed) and storage required to fulfill a workload need. The VMware Cloud Foundation composability layer can create a composed server by allocating the appropriate storage drives to a compute sled.  Once composed, a server can be commissioned to be used in a workload domain.The VMware Cloud Foundation interface also allows the decomposition of a composed system (which removes all assigned resource blocks such as storage) or add/remove storage capacity.The path aheadGartner says “Today, composable infrastructure is held back by a lack of technology to disaggregate DRAM from processors, industry-standard configurable fabrics and cross-vendor APIs.[i]” We believe the best way to address the cross-vendor API issue is through Redfish. The work Dell Technologies and VMware have done shows how we can manage composability through workload orchestration software utilizing standard APIs. Navigating the path forward and addressing Gartner’s other concerns which we believe requires expanding the mechanisms we developed with the MX7000 and VMware Cloud Foundation beyond SAS storage composition. Industry efforts such as NVMe-over-Fabrics (NVMeOF) will allow the disaggregation of NVMe storage devices. Other industry efforts, such as Gen-Z, will allow the disaggregation of memory devices, like storage class memory (SCM), and accelerators. Dell Technologies’ kinetic infrastructure with its utilization of industry standard Redfish APIs can adopt new technologies as they mature, expanding the types of resources that can be composed.If you are attending Dell Technologies World 2020 be sure to attend the breakout track, “Bringing Cloud Automation and Agility to Your Data Center with Dell Technologies Cloud,” where we will discuss how a software-defined data center approach with kinetic architecture and VMware Cloud Foundation can provide customization and flexibility for bridging your data center operations on the ground into SDDC and cloud.

Transforming Storing – and Processing – of Video Data

first_imgInnovation in technology changes more than just the tools organizations use. It also fundamentally changes how organizations operate. This is quite evident for companies working with video. The exponential rise in data exacerbates throughput, efficiency, scalability, and reliability issues. To stay profitable, they must update their equipment as well as transform their internal work processes.Consider the difficulties faced by EarthCam, a provider of webcam technology and managed services consisting of streaming video, time-lapse movies, and 360° reality capture. Every month, the company brings millions of high-resolution images into their network. To date, their database contains over a billion files ranging from one to 24 MB in size. The vast number of files created complexity in their storage system. One way to manage different types of data is to put them in different silos. While this makes it easier to manage each type of data individually, it complicates overall storage management because each silo needs to be managed differently in terms of factors such as RAIDs, RAID groups, and protocols. Scaling was also challenging because each addition to the network increased the complexity of managing the overall storage array.Working with stored data was also quite inefficient. For many of its clients, EarthCam creates time-lapse movies, such as compressing images of a three-month construction project into a one-minute video. Each image in the time-lapse movie needs to be hand-selected from the tremendous number of images available and then enhanced to provide a consistent look and feel. Traditionally, the entire image set is downloaded to the editor’s workstation. Downloading this much data puts a strain on available bandwidth and causes delays across all network workloads.EarthCam also wanted to reduce its operating costs without compromising efficiency, quality, or reliability. And, with rising success came the need to easily scale storage while simplifying overall management of the network.Increased Efficiency, Productivity, and Operational SavingsDell EMC PowerScale storage, the next-generation scale-out storage of the Emmy-winning Isilon lineage, is designed for applications with data requirements ranging from terabytes up to 10 petabytes – the right platform for EarthCam. Typical storage utilization tops out at 66%. The advanced capabilities of PowerScale – including globally coherent cache, load-balancing, and automated tiering – increase performance efficiency for every application and deliver 80%+ utilization.EarthCam’s new system did more than just storing data. By adding a cluster of fast-performing PowerScale nodes, EarthCam was able to shift their video-editing platform to become local with image data. Now, instead of downloading an entire timeline of images, editors work with just the data they need to complete their job.<span style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” data-mce-type=”bookmark” class=”mce_SELRES_start”></span> For example, for a time-lapse movie, editors can select the images to use from thumbnails rather than hi-res originals. These thumbnails are created on processing resources local to the stored images, reducing how much data needs to be downloaded by orders of magnitude. This in turn leads to direct operational savings, both in terms of bandwidth and the time it takes to complete a task. For EarthCam, working locally reduced processing time for the video production team by 20%.The savings did not stop there. PowerScale doubled EarthCam’s storage capacity while actually reducing the rack space needed. Overall, they were able to achieve about 26X greater density and 100X faster sustained throughput compared to their previous storage implementation.Seamless Scalability and Ease of UseAnother important requirement for EarthCam was simplified network management. Typical storage scaling is achieved by adding “bricks” of storage. The problem with this approach is that LUNs need to be set up and each node needs to be managed. With PowerScale, IT plugs in a new node and, without needing to reconfigure the data pool, data is immediately migrated over to the new node to balance the load across the entire array and maximize performance. Adding a node in this way is relatively seamless and can be completed with no downtime.EarthCam was able to simplify day-to-day management by consolidating petabytes of different types of data in one location, eliminating the need for data silos and managing different storage systems. Single volume / single file system / single namespace consolidation both on-premises and in the cloud greatly simplifies workflows. Eliminating silos also enables greater collaboration between groups who can now share collaborative tools and data assets.PowerScale InsightIQ and other tools provide greater visibility into storage processes and network loads. With such visibility, IT doesn’t have to work down into the stack to manage the network. For example, EarthCam can manage their network, such as changing performance on directories based on usage, without having to worry about specific LUNs, and such changes take just minutes to apply. In short, a single person can manage petabytes of different types of data. This frees up IT personnel from managing data storage, enabling them to focus on optimizing applications and how data can be used more efficiently.Upgrading to next-generation PowerScale technologies has been seamless as well. After plugging in new PowerScale nodes, the OS can be configured to begin evacuating data from nodes to be retired into the new nodes. The entire migration can take place with zero downtime.Ease of use has translated directly to the bottom line for EarthCam: since implementing PowerScale, they have had an 82% reduction in systems administration resources and been able to maintain five nines (99.999%) uptime.Transforming a business doesn’t have to be hard. The fact is, simplifying transformation is the core job of technology companies. At Dell Technologies, we understand that increasing the efficiency of business operations is just the first step. Part of bringing innovation to market is helping facilitate the business transformations that are essential to the process of growth.last_img read more

Iran says it also expects Washington to swiftly lift crippling economic sanctions that former President Donald Trump imposed on the country after pulling America out of the atomic accord in 2018 as part of what he called maximum pressure against Iran. Iran’s Cabinet spokesman Ali Rabiei said on Tuesday that the U.S. “will not have all the time in the world” to return to the nuclear deal. President Joe Biden has said pledged to return to the accord.last_img

Moscow court puts Navalny’s allies under house arrest

first_imgA court in Moscow has put the brother and several allies of Russian opposition leader Alexei Navalny under house arrest as authorities sought to stymie more protests over the anti-corruption investigator’s jailing. Navalny’s supporters are calling for rallies on Sunday to demand his freedom. The 44-year-old is the best-known critic of President Vladimir Putin’s government. He, was arrested Jan. 17 upon returning from Germany, where he spent five months recovering from nerve-agent poisoning that he blames on the Kremlin. Russian authorities reject the accusations. Navalny was jailed for 30 days after Russia’s prison service alleged he violated the probation terms of his suspended sentence from a money-laundering conviction that he rejects as politically motivated.last_img

Funeral for Scottsboro Boys Museum founder Sheila Washington

first_imgSCOTTSBORO, Ala. (AP) — A funeral has been held for Sheila Washington, founder of the Scottsboro Boys Museum and Cultural Center in Alabama. The museum is dedicated to exploring the racial injustice committed against nine young African-Americans falsely accused of raping two white women in 1930s Alabama. Washington died Jan. 29 at age 61 and her funeral was held Saturday. She opened the Scottsboro, Alabama, museum in 2010. It sheds light on the case of the nine young Blacks who faced all-white juries. All but the youngest defendant were sentenced to death. Five of the men’s convictions were overturned in 1937 and all were ultimately freed and exonerated.last_img
