Today is the big day in 2019 for Intel’s Enterprise product announcements, combining some products that should be available from today and a few others set to be available in the next few months. Rather than go for a staggered approach, we have it all in one: processors, accelerators, networking, and edge compute. Here’s a quick run-down of what’s happening today, along with links to all of our deeper dive articles, our reviews, and announcement analysis.

Cascade Lake: Intel’s New Server and Enterprise CPU

The headliner for this festival is Intel’s new second-generation Xeon Scalable processor, Cascade Lake. This is the processor that Intel will promote heavily across its enterprise portfolio, especially as OEMs such as Dell, HP, Lenovo, Supermicro, QCT, and others all update their product lines with the new hardware. (You can read some of the announcements here: Dell on AT, Supermicro on AT, Lenovo on AT, Lenovo at Lenovo.)

While these new CPUs do not use a new microarchitecture compared to the first generation Skylake-based Xeon Scalable processors, Intel surprised most of the press at its Tech Day with the sheer number of improvements in other areas of Cascade Lake. Not only are there more hardware mitigations against Spectre and Meltdown than we expected, but we have Optane DC Persistent Memory support. The high-volume processors get a performance boost by having up to 25% extra cores, and every processor gets double the memory support (and faster memory, too). Using the latest manufacturing technologies allows for frequency improvements, which when combined with new AVX-512 modes shows some drastic increases in machine learning performance for those that can use them.

New to the Xeon Scalable family is the AP line of processors. Intel gave a hint to these late last year, but we finally got some of the details. These new Xeon Platinum 9200 family of parts combine two 28-core bits of silicon into a single package, offering up to 56 cores and 112 threads with 12 channels of memory, in a thermal envelope up to 400W. This is essentially a 2P configuration on a single chip, and is designed for high-density deployments. These BGA-only CPUs will only be sold with an underlying Intel-designed platform straight from OEMs, and will not have a direct price – customers will pay for ‘the solution’, rather than the product.

For this generation, Intel will not be producing models with ‘F’ Omnipath fabric on board. Instead, users will have some ‘M’ models with 2 TB memory support and ‘L’ models with 4.5 TB memory support, focused for the Optane markets. There will also be other letter designations, some of them new:

  • M = Medium Memory Support (2.0 TB)
  • L = Large Memory Support (4.5 TB)
  • Y = Speed Select Models (see below)
  • N = Networking/NFV Specialized
  • V = Virtual Machine Density Value Optimized
  • T = Long Life Cycle / Thermal
  • S = Search Optimized

Out of all of these, the Speed Select ‘Y’ models are the most interesting. These have additional power monitoring tools that allow for applications to be pinned to certain cores that can boost higher than other cores – distributing the power available to different places on the cores based on what needs to be prioritized. These parts also allow for three different OEM-specified base and turbo frequency settings, so that one system can be focused of three different types of workloads. 

We are currently in the process of writing our main review, and plan to tackle the topic from several different angles in a number of stories. Stay tuned for that. We do have the SKU lists and our launch day news found here:

The Intel Second Generation Xeon Scalable:
Cascade Lake, Now with Up To 56-Cores and Optane!

The other key element to the processors is the Optane support, discussed next.

Optane DCPMM: Data Center Persistent Memory Modules

If you’re confused about Optane, you are not the only one.

Broadly speaking, Intel has two different types of Optane: Optane Storage, and Optane DIMMs. The storage products have already been in the market for some time, both in consumer and enterprise, showing exceptional random access latency above and beyond anything NAND can provide, albeit for a price. For users that can amortize the cost, it makes for a great product for that market.

Optane in the memory module form factor actually works on the DDR4-T standard. The product is focused for the Enterprise market, and while Intel has talked about ‘Optane DIMMs’ for a while, today is the ‘official launch’. Select customers are already testing and using it, while general availability is due in the next couple of months.

Optane DC Persistent Memory, to give it its official title, comes in a DDR4 form factor and works with Cascade Lake processors to enable large amounts of memory in a single system – up to 6TB in a dual socket platform. The Optane DCPMM is slightly slower than traditional DRAM, but allows for a much higher memory density per socket. Intel is set to offer three different sized modules, either 128 GB, 256 GB, or 512 GB. Optane doesn’t replace DDR4 entirely – you need at least one module of standard DDR4 in the system to get it to work (it acts like a buffer), but it means customers can pair 128GB DDR4 with 512 GB Optane for 768 GB total, rather than looking at a 256 GB of pure DDR4 backed with NVMe.

With Optane DCPMM in a system, it can be used in two modes: Memory Mode and App Direct.

The first mode is the simplest mode to think about it: as DRAM. The system will see the large DRAM allocation, but in reality it will use the Optane DCPMM as the main memory store and the DDR4 as a buffer to it. If the buffer contains the data needed straight away, it makes for a standard DRAM fast read/write, while if it is in the Optane, it is slightly slower. How this is negotiated is between the DDR4 controller and the Optane DCPMM controller on the module, but this ultimately works great for large DRAM installations, rather than keeping everything in slower NVMe.

The second mode is App Direct. In this instance, the DRAM acts like a big storage drive that is as fast as a RAM Disk. This disk, while not bootable, will keep the data stored on it between startups (an advantage of the memory being persistent), enabling very quick restarts to avoid serious downtime. App Direct mode is a little more esoteric than ‘just a big amount of DRAM’, as developers may have to re-architect their software stack in order to take advantage of the DRAM-like speeds this disk will enable. It’s essentially a big RAM Disk that holds its data. (ed: I’ll take two)

One of the issues, when Optane was first announced, was if it would support enough read/write cycles to act as DRAM, given that the same technology was also being used for storage. To alleviate fears, Intel is going to guarantee every Optane module for 3 years, even if that module is run at peak writes for the entire warranty period. Not only does this mean Intel is placing its faith and honor into its own product, it even convinced the very skeptical Charlie from SemiAccurate, who has been a long-time critic of the technology (mostly due to the lack of pre-launch information, but he seems satisfied for now).

Pricing for Intel’s Optane DCPMM is undisclosed at this point. The official line is that there is no specific MSRP for the different sized modules – it is likely to depend on which customers end up buying into the platform, how much, what level of support, and how Intel might interact with them to optimize the setup. We’re likely to see cloud providers offer instances backed with Optane DCPMM, and OEMs like Dell say they have systems planned for general availability in June. Dell stated that they expect users who can take advantage of the large memory mode to start using it first, with those who might be able to accelerate a workflow with App Direct mode taking some time to rewrite their software.

It should be noted that not all of Intel's second generation Xeon Scalable CPUs support Optane. Only Xeon Platinum 8200 family, Xeon Gold 6200 family, Xeon Gold 5200 family, and the Xeon Silver 4215 does. The Xeon Platinum 9200 family do not.

Intel has given us remote access into a couple of systems with Optane DCPMM installed. We’re still going through the process of finding the best way to benchmark the hardware, so stay tuned for that.

Intel Agilex: The New Breed of Intel FPGA

The acquisition of Altera a couple of years ago was big news for Intel. The idea was to introduce FPGAs into Intel’s product family and eventually realize a number of synergies between the two, integrating the portfolio while also aiming to take advantage of Intel’s manufacturing facilities and corporate sales channels. Despite that happening in 2015, every product since was developed prior to that acquisition, prior to the integration of the two companies – until today. The new Agilex family of FPGAs is the first developed and produced wholly under the Intel name.

The announcement for Agilex is today, however the first 10nm samples will be available in Q3. The role of the FPGA has been evolving of late, from offering a general purpose spatial compute hardware to offering hardened accelerators and enabling new technologies. With Agilex, Intel aims to offer that mix of acceleration and configuration, not only with the core array of gates, but also by virtue of additional chiplet extensions enabled through Intel’s Embedded Multi-Die Interconnect Bridge (EMIB) technology. These chiplets can be custom third-party IP, PCIe 5.0, HBM, 112G transceivers, or even Intel’s new Compute eXpress Link cache coherent architecture. Intel is promoting up to 40 TFLOPs of DSP performance, and is promoting its use in mixed precision machine learning, with hardened support for bfloat16 and INT2 to INT8.

Intel will be launching Agilex in three product families: F, I, and M, in that order of both time and complexity. The Intel Quartus Prime software to program these devices will be updated for support during April, but the first F models will be available in Q3.

Columbiaville: Going for 100GbE with Intel 800-Series Controllers

Intel currently offers a lot of 10 gigabit Ethernet and 25 gigabit Ethernet infrastructure in the data center. The company launched 100G Omnipath a few years ago as an early alternative, and is looking towards a second generation of Omnipath to double that speed. In the meantime Intel has developed and is going to launch Columbiaville, its controller offering for the 100G Ethernet market, labeled as the Intel 800-Series.

Introducing faster networking to the data center infrastructure is certainly a positive, however Intel is keen to promote a few new technologies with the product. Application Design Queues (ADQs) are in place to help hardware accelerate priority packets to ensure consistent performance, while Dynamic Device Personalization (DDP) enables additional programming functionality within packet sending for unique networking setups to allow for additional functionality and/or security.

The dual-port 100G card will be called the E810-CQDA2, and we’re still waiting information about the chip: die size, cost, process, etc. Intel states that its 100 GbE offerings will be available in Q3.

Xeon D-1600: A Generational Efficiency Improvement for Edge Acceleration

One of Intel’s key product areas is the edge, both in terms of compute and networking. One of the products that Intel has focused on this area is Xeon D, which covers either the high efficiency compute with accelerated networking and cryptography (D-1500) and the high throughput compute with accelerated networking and cryptography (D-2100). The former being Broadwell well based and the latter is Skylake based. Intel’s new Xeon D-1600 is a direct D-1500 successor: a true single-die solution taking advantage of an additional frequency and efficiency bump in the manufacturing process. It is still built on the same manufacturing process as D-1500, allowing Intel’s partners to easily drop in the new version without many functional changes.

    Weird as Opteron back in the day had like 20%+ market share. We were still using Opteron servers in our HPC environment in 2009.

    Admittedly AMD have had no worthwhile offering for the last 10years - and in that 10 years of no competition Intel has fleeced its customers.

    Very shortly you will be able to get higher core count, higher performance, less power and a much more secure processor for LESS money than anything Intel has to offer.

    Couple this with how Intel has treated its customers - there will be a huge uptake in EPYC processors for the data centre.

    Intel advise to turn off Hyperthreading in these new cascade lake AP chips due to security vulnerabilities!

    just out of curiosity... do these 'chips' implement more address lines? or is Intel/AMD still at the same number (48? 52?) below the 64 bit address space?
  • Billy Tallis - Saturday, April 6, 2019 - link

    /proc/cpuinfo reports 46 bits physical, 48 bits virtual on Cascade Lake-SP, same as for Skylake-SP. (Desktop Skylake reports 39 bits physical, 48 bits virtual.)
