SAP HANA is one of those demanding workloads that has been steadfastly contained within the clean walls of the core data center. However, this time last year VxRail began to chip away at these walls and brought you SAP HANA certified configurations based on the VxRail all-flash P570F workhorse and powerful quad socket all-NVMe P580N. This year, we are once again in the giving mood and are bringing SAP HANA to the edge. Let us explain.

Dell Technologies defines the edge as “The edge exists wherever the digital world & physical world intersect. It’s where data is securely collected, generated and processed to create new value.” This is a very broad definition that extends the edge from the data center to oil rigs, to mobile response centers for natural disasters. It is a broad claim not only to provide compute and storage in such harsh locations, but also to provide enough of it that meets the strict and demanding needs of SAP HANA, all while not consuming a lot of physical space. After all -- it is the edge where space is at a premium.
Shrinking the amount of rack space needed was the easier of the two challenges, and our 1U E for Everything (or should that be E for Everywhere?) was a perfect fit. The all-flash E560F and all-NVMe E560N, both of which can be enhanced with Intel Optane Persistent Memory, can be thought of as the shorter sibling of our 2U P570F, packing a powerful punch with equivalent processor and memory configurations.
While the E Series fits the bill for space constrained environments, it still needs data center like conditions. This is not the case for the durable D560F, the tough little champion that joined the VxRail family in June of this year, and which is now the only SAP HANA certified ruggedized platform in the industry. Weighing in at a lightweight 28 lbs. and a short depth of 20 inches, this little fighter will run all day at 45°C with eight hour sprints of up to 55°C, all while enduring shock, vibration, dust, humidity, and EMI, as this little box is MIL-STD 810G and DNV-GL Maritime certified. In other words, if your holiday plans involve a trip to hot sand beaches, a ship cruise through a hurricane, or an alpine climb, and you’re bringing SAP HANA with you (we promise we won’t ask why), then the durable D560F is for you.
The best presents sometimes come in small packages. So, we won’t belabor this blog with anything more than to announce that these two little gems, the E560 and the D560, are now SAP HANA certified.

New all-NVMe VxRail platforms deliver highest levels of performance

Two new all-NVMe VxRail platforms deliver highest levels of performance
December 11, 2019
If you have not been tuned into the VxRail announcements at VMworld Barcelona last month, this is news to you. VxRail is adding more performance punch to the family with two new all-NVMe platforms. The VxRail E Series 560N and P Series 580N, with the 2nd Generation Intel® Xeon® Scalable Processors, offer increased performance while enabling customers to take advantage of decreasing NVMe costs.
Balancing workload and budget requirements, the dual-socket E560N provide a cost-effective, space-efficient 1U platform for read-intensive workloads and other complex workloads. Configured with up to 32TB of NVMe capacity, the E560N is the first all-NVMe 1U VxRail platform. Based on the PowerEdge R640, the E560N can run a mix of workloads including data warehouses, ecommerce, databases, and high-performance computing. With support for Nvidia T4 GPUs, the E560N is also equipped to run a wide range of modern cloud-based applications, including machine learning, deep learning, and virtual desktop workloads.
Built for memory-intensive high-compute workloads, the new P580N is the first quad-socket and also the first all-NVMe 2U VxRail platform. Based on the PowerEdge R840, the P580N can be configured with up to 80TB of NVMe capacity. This platform is ideal for in-memory databases and has been certified by SAP for SAP HANA. The P580N provides 2x the CPU compared to the P570/F and offers 25% more processing potential over virtual storage appliance (VSA) based 4-socket HCI platforms that require a dedicated socket to run (VSA).
The completion of the SAP HANA certification for the P580N which coincides with the P580N’s general availability demonstrates the ongoing commitment to position VxRail as the HCI platform of choice for SAP HANA solutions. The P580N provides even more memory and processing power than the SAP HANA certified P570F platform. An updated Validation Guide for SAP HANA on VxRail will be available in early January on the Dell EMC SAP solutions landing page for VxRail.

Enhancing Satellite Node Management at Scale
Tue, 15 Mar 2022 20:30:40 -0000

Satellite nodes are a great addition to the VxRail portfolio, empowering users at the edge, as described in David Glynn’s blog Satellite Nodes: Because sometimes even a 2-node cluster is too much. Although satellite nodes are still new, we’ve been working hard and have already started making improvements. Dell’s latest VxRail 7.0.350 release has a number of new VxRail enhancements and in this blog we’ll focus on these new satellite node features:
- Improved life cycle management (LCM)
- New APIs
- Improved security
Improved LCM
The first way we’ve improved satellite nodes is by reducing the required maintenance window. To do this, the satellite node update process has now been split in two. Instead of staging the recovery bundle and performing the update in one step, you can now stage the recovery bundle and perform the update separately.
Staging the bundle in advance is great because we know bandwidth can be limited at the edge and this allows ample time to transfer the bundle in advance to ensure your update happens during your scheduled maintenance window. Once your bundles are staged, it’s as simple as scheduling the updates and letting VxRail execute the node update. This improvement ensures that you can complete the update within the expected timeframe to minimize downtime. Satellite nodes sit outside the cluster and, as a result, workloads will go offline while the node is updated.
New APIs
Do you have a large number of edge locations that could use satellite nodes and need an easier way to manage at scale? Good news! These new APIs are perfect for making edge life at scale easier.
The new APIs include:
- Satellite node LCM
- Add a satellite node to a managed folder
- Remove a satellite node from a managed folder
The introductory release of VxRail satellite nodes featured LCM operations through the VxRail Manager plug-in, which could be quite time consuming if you are managing a large number of satellite nodes. We saw room for improvement so now administrators can use VxRail APIs to add, update, and remove satellite nodes to simplify and speed up operations.
You can use the satellite node LCM API to adjust configuration settings that benefit management at scale, such as adjusting the number of satellite nodes you want to update in parallel. For example, although the default is to update 20 nodes in parallel, you can initiate updates for up to 30 satellite nodes in parallel, as needed.
There is also a failure rate feature that will set a condition to exit from an LCM operation. For example, if you are updating multiple satellite nodes at one time and nodes are failing to update, the failure rate setting is a way to abort the operation altogether if the rate surpasses a set threshold. The default threshold is 20% but can be set anywhere from 1% to 100%. Using the VxRail API, you can adjust settings like this that are not available in the VxRail Manager.
These new APIs are great for users with a large number of VxRail satellite nodes. Adding, removing, and updating satellite nodes can now be automated through the new APIs, saving you precious time across your edge locations.
Improved Security
VxRail satellite nodes can now use Secure Enterprise Key Management (SEKM), made available through the Dell PowerEdge servers that VxRail is built on. What is SEKM you might ask? Well, SEKM gives you the ability to secure drive access using encryption keys stored on a central key management server (not on the satellite node).
SEKM is great for many reasons. First, an edge location might be more exposed and have less physical security than your typical data center but that doesn’t mean securing your data is any less important. SEKM keeps your data drives locked even if the entire server is stolen. When paired with self-encrypting drives, you can secure the data even further. Second, the encryption keys are stored in a centralized location, making it easier to manage the security of large numbers of satellite nodes instead of having to manage each satellite node individually.
In this blog we’ve highlighted some exciting new satellite node features, including an improved update process, new APIs, and enhanced security, all of which enhance managing the edge at scale.
