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.

Deploying SAP HANA at the Rugged Edge

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.

VxRail’s Latest Hardware Evolution
Thu, 04 Jan 2024 17:22:21 -0000

December is a time of celebration and anticipation, a month in which we may reflect on the events of the year and look ahead to what is yet to come. Charles Dickens’ “A Christmas Carol” – and its many stage and movie remakes – is one of those literary classics that helps showcase this season’s magic at its finest. It is even said that there is a special kind of magic—one full of excitement, innovation, and productivity—that finds a way to (hyper)converge the past, present, and future for data center administrators all around the world who have been good all year!
No, your wondering eyes do not deceive you. Appearing today are VxRail’s next generation platforms—the VE-660 and VP-760—in all-new, all-NVMe configurations! While Santa’s elves have spent the year building their backlog of toys and planning supply-chain delivery logistics that rival SLA standards of the world’s largest e-tailers, the VxRail team has been hard at work innovating our VxRail family portfolio to ensure that your workloads can run faster than ever before. So, let’s grab a glass of eggnog and invite the holiday spirits along for a tour of VxRail past, present, and future to better understand our latest portfolio addition.
Spirit of VxRail Past
When VxRail first launched almost 8 years ago in early 2016, we introduced the concept of hyperconverged infrastructure to the masses with one easily-managed platform that combined best-of-breed Dell PowerEdge servers with VMware technology. This new age of data center management brought better performance, extended capabilities, and time-saving advantages to data center admins everywhere. Over the years, we’ve sought to improve the offering by taking advantage of the latest hardware standards and technologies.
This was especially true earlier this summer when we launched the VE-660 and VP-760 VxRail platforms based on 16th Generation Dell PowerEdge servers. These next-gen successors to the VxRail E-Series and P-Series platforms not only contained the latest hardware innovations, but also represented a systemic change in the overall VxRail offering.
First, the mainline E- and P-series platforms were respectively re-christened as the VE-660 and VP-760. This was done primarily to invite easier comparison points to the underlying PowerEdge servers on which they’re based – the R660 and R760. Second, we tracked how the use of accelerators in the data center had evolved over the years and made the strategic decision to fold the capabilities of the V-Series platform into the P-Series by way of specific riser configurations. Now, customers have the ability to glean all the benefits of a high-performant 2U system with the choice of either storage-optimized (up to 28 total drive bays) or accelerator-optimized (up to 2x double wide or 6x single wide GPUs) chassis configurations—whichever best aligns to the specifics of their workload needs. And third, VxRail platforms dropped the storage type suffix from the model name. Hybrid and all-flash (and as of today, all-NVME–more on this later) storage variants are now offered as part of the riser configuration selection options of these baseline platforms, where applicable.
These changes are representative of how the breadth and depth of customer needs have grown tremendously over the years. By taking these steps to streamline the VxRail portfolio, we charted an evolutionary path forward that continues our commitment to offer greater customer choice and flexibility.
Spirit of VxRail Present
These themes of greater choice and flexibility are amplified by the architectural improvements underpinning these new VxRail platforms. Primary among them is the introduction of Intel® 4th Generation Xeon® Scalable processors. Intel’s latest generation of processors do more than bump VxRail core density per socket to 56 (112 max per node). They also come with built-in AMX accelerators (Advanced Matrix Extensions) that support AI and HPC workloads without the need for any additional drivers or hardware. For a deeper dive into the Intel® AMX capability set, the Spirit of VxRail Present invites you to read this blog: VxRail and Intel® AMX, Bringing AI Everywhere, authored by Una O’Herlihy.
Intel’s latest processors also usher in support for DDR5 memory and PCIe Gen 5, two other architectural pillars that underpin significant jumps in performance. The following table offers a high-level overview and comparison of these pillars and a useful at-a-glance primer for those considering a technology refresh from earlier generation VxRail:
Table 1. VxRail 14th Generation to 16th Generation comparison
VxRail VE-660 & VP-760 | VxRail E560, P570 & V570 | |
Intel Chipset | 4th Generation Xeon | 2nd Generation Xeon |
Cores | 8 - 56 | 4 - 28 |
TDP | 125W – 350W | 85W – 205W |
Max DRAM Memory | 4TB per socket | 1.5TB per socket |
Memory Channels | 8 (DDR5) | 6 (DDR4) |
Memory Bandwidth | Up to 4800 MT/s | Up to 2933 MT/s |
PCIe Generation | PCIe Gen 5 | PCIe Gen 3 |
PCIe Lanes | 80 | 48 |
PCIe Throughput | 32 GT/s | 8 GT/s |
As the operational needs of a business change day-by-day, finding the right balance between workload density and load balance can often feel like an infinite war for resources. The adoption of DDR5 memory across the latest generation of VxRail platforms offers additional flexibility in the way system resources can be divvied up by virtue of two key benefits: greater memory density and faster bandwidth. The VE-660 and VP-760 wield eight memory channels per processor, with the ability to slot up to two 4800MT/s DIMMs per channel for a maximum memory capacity of 8TB per node. Compared to a VxRail P570, the density and speed improvements are staggering: 33% more memory channels per processor, 2.6x increase in per system total memory, and up to a 64% increase in memory speed! With faster and greater density compute and memory available for workloads, each node in a VxRail cluster can handle more VMs, and if there is ever a case of task bottlenecking, there are plenty of resources still available for optimal load balancing.
When we consider the presence of PCIe Gen 5, we see an even greater increase in the overall performance envelope. PowerEdge’s Next-Generation Tech Note does a great job of contextualizing the capabilities of PCIe Gen 5. The main takeaway for VxRail, however, is that it increases the maximum bandwidth achievable from various peripheral components by roughly 25% when compared to PCIe Gen 4 and roughly 66% when compared to PCIe Gen 3. In particular, the jump in available PCIe lanes (48 lanes to a luxurious 80 lanes) and associated throughput (8 GT/s to 32 GT/s per lane) from Gen 3 to Gen 5 significantly reduces performance bottlenecks, resulting in faster storage transfer rates and more bandwidth for accelerators to process AI and ML workloads.
PCIe Gen 5 is also backwards compatible with previous generation peripherals, enabling a certain degree of flexibility with respect to VxRail’s component extensibility and longevity in the data center. Yesterday’s technologies can still be used, but the VE-660 and VP-760 can adapt to growing workload demands by taking full advantage of the latest peripherals as they are released. They are even equipped with an additional PCIe slot over their E- & P-Series predecessors, providing extra dimensions of configuration. These boons in flexibility ensure any investment into this generation of VxRail enjoys longer relevance as your infrastructure backbone.
Spirit of VxRail Future
Even with all these architectural improvements defining the VP-760 and VE-660, we knew we could find ways of improving the capability set. So, we made our list of desired features (and checked it twice!) and determined that the best way to augment these next-generation hardware enhancements would be with the introduction of all-NVMe storage options.
The Spirit of VxRail Past wishes to remind us that VxRail with all-NVMe storage is not new—NVMe first made its way to the VxRail lineup with the P580N and E560N almost four years ago and has been a mainstay facet of the VxRail with vSAN architecture ever since. However, what is most compelling about all-NVMe versions of the VE-660 and VP-760—what the Spirit of VxRail Future wishes to strongly communicate—is that NVMe opens the door to two very compelling benefits: additional flexibility of choice with respect to vSAN architecture and an associated increase in overall storage capacity with the addition of read intensive NVMe drives in sizes of up to 15.36TB.
The following figure outlines all of the generational advantages customers can benefit from when transitioning from existing 14th Generation VxRail environments to VP-760 all-NVMe platforms.
In addition, VxRail on 16th Generation hardware can now support deployments with either vSAN Original Storage Architecture (OSA) or vSAN Express Storage Architecture (ESA). David Glynn provided a great summary of the core value vSAN ESA brings to the table for VxRail in his blog written nearly a year ago. With today’s launch, the VP-760 and VE-660 can now take advantage of vSAN ESA’s single-tier storage architecture that enables RAID-5 resiliency and capacity with RAID-1 performance. Customers who choose to deploy with vSAN OSA can also see the benefit of these new read intensive NVMe drives, with a total storage per node of up to 122.88TB in the VE-660 and 322.56TB in the VP-760. For those who deploy with vSAN ESA, maximum achievable storage is 153.6TB on the VE-660 and up to 368.64TB on the VP-760.
The Spirit of VxRail Future has seen the value of all-NVMe and is content knowing that VxRail will continue to underpin VMware mission-critical workloads for years to come.
