AMD Unveils 64-Bit ARM-Based Opteron A1100 System On Chip With Integrated 10GbE (hothardware.com) 98

MojoKid writes: AMD is adding a new family of Opterons to its enterprise processor line-up today called the Opteron A1100 series. Unlike AMD's previous enterprise offerings, however, these new additions are packing ARM-based processor cores, not the X86 cores AMD has been producing for years. The Opteron A1100 series is designed for a variety of use cases and applications, including networking, storage, dense and power-efficient web serving, and 64-bit ARM software development. The new family was formerly codenamed "Seattle" and it represents the first 64-bit ARM Cortex-A57-based platform from AMD. AMD Opteron A1100 Series chips will pack up to eight 64-bit ARM Cortex-A57 cores with up to 4MB of shared Level 2 and 8MB of shared Level 3 cache. They offer two 64-bit DDR3/DDR4 memory channels supporting speeds up to 1866 MHz with ECC and capacities up to 128GB, dual integrated 10Gb Ethernet network connections, 8-lanes of PCI-Express Gen 3 connectivity, and 14 SATA III ports. AMD is shipping to a number of software and hardware partners now with development systems already available.

    • "Enterprise is a much bigger market" is what I'd otherwise say, but seeing as that (and datacenters) runs on vmware, I doubt this will see that much adoption. Unless of course the value prop is so good that open source virtualization (I.e. xen) starts running on it.

            Not true for databases or Java servlet apps. It is latency based. Latency on networks and disk i/o as your SQL query gets processed and the CPU goes on massive WAIT cycles in the process.

            An ARM will be great for lower power with an SSD and lots of bandwidth.

          • Could well be useful for memcache-type applications. Not likely to be terribly powerful; but quite possibly one of the cheaper ways to get 128GB of ECC RAM into a small box(Intel's C2000 Atom-for-server stuff currently tops out at 64GB, and their Xeons cost more).

          On Linux you'd still get better hardware/software support on x86, and better performance/ dollar, or performance per watt.

          I could certainly see this maybe in embedded applications, and maybe networking appliances (like a storage server, or maybe a web server). But I think it will be a few years still before you see a big foothold of ARM based CPUs in general purpose servers.

      As much as I think that this is probably the "best" ARM server at the moment, I 100% agree with you. Its not going to make AMD any real money, and the amount of R&D invested would have been better spent upgrading their existing product lines.

    Only X8 pci-e?

    At least they have dual 10-gige but come on give at least x16 pci-e even if you need to cut down the sata links.

    • For what purpose? These are obviously meant for the server room. What need do you have for anything beyond pci-e X8 if you don't even have a video card?

      • Some servers do have video cards. We have them in lots of our servers for GPU compute tasks.
        • So would your GPU compute servers benefit from having an ARM instead of x86 CPU?

          Clearly, there is some market where the workload favors ARM CPUs, and some market where the workload favors GPU computing (and therefore PCIe x16). Combining both in the same product only makes sense if there's some market that needs both at the same time. It's not as if AMD were discontinuing x86 Opterons, after all.

          • by Junta ( 36770 )

            Well, maybe if the ARM servers did NV-Link. POWER and ARM can do NV-Link CPU to GPU, Intel however was either not invited to the party or was disinterested in working to enable it. Of course I'm suspecting AMD and nVidia collaborating would be unlikely

            Again though, there'd be no room to complain about PCIe lanes.

            • NV-Link just sounds like an Nvidia copy of Hypertransport [amd.com].

              • by Junta ( 36770 )

                Roughly, it is. However that has never been used to connect a discrete GPU to a CPU, to my knowledge. AMD did it first, Intel copied it, and nVidia has joined the world of proprietary interconnects, but the first to do so for CPUGPU situation.

                • I think AMD uses Hypertransport in its APUs, but yeah, I've been wishing for years for an AMD FX (or Phenom II) + discrete Radeon setup that used it (maybe with the GPU in a motherboard socket instead of a daughter card, although I guess the hard part of that is the lack of standards for slotted graphics RAM).

          • Combining both in the same product only makes sense if there's some market that needs both at the same time.

            While it might seem silly to try to save ~100W in a system that contains ~1000W of GPUs, that still adds up to another whole node relatively rapidly. If you're using pretty much all GPU and basically no CPU, it might make good sense. Isn't that a fairly common case now? With the 10GbE they are attractive cluster nodes. It might not have the crazy low latency of some of the more specialized interconnects, but it's still damned fast.

              Still for rendering tasks, a large part of the bus is needed for moving large textures in and out of memory. While I am not an expert in this field, I do not think may of the other current GPU compute tasks require this memory bandwidth, so as large a bus is not needed.

          • by dbIII ( 701233 )
            They do if your task requires using a lot more memory than the cards have onboard. At that point as much bandwidth as you can get never seems like enough.

          If you are doing GPU compute, you are unlikely to be interested in ARM. Those GPU's need to be fed somehow with data somehow, and the ARM won't keep up.

          We are still not at the point where GPU's can just fetch a bunch of data over the network by themselves, crunch it, and send it out again.

      You only need enough I/O to attach a few disks or a controller to attach to a SAN or something like infiniband and x8 is plenty. You could attach a single GPGPU as well but I don't think that would be a target application. (Does Nvidia even have Tesla support for ARM platforms?)

The dual 10Gb ethernet ports alone indicate a a combination of high I/O throughput and redundancy, not merely an application node.

          8x PCIe v3 gives you 7,880MB/s. Even just throwing the data out over the two 10GigE connectors, you'll only use a third of that. I doubt that 8 Cortex-A57 cores are going to find themselves data starved processing the rest.

    10GbE Ethernet, (at least over copper, which is the only way I've gotten to mess with it), kinda sucks. Cost per port is really high and actually so are the power requirements per port. Infiniband was a lot easier and cheaper for me to deal with and having it implemented in relatively common hardware might improve its adoption.

    • by Anonymous Coward

      I desperately want an affordable home switch/router with a single 10Gb port. My server can feed around 400MB/s from its raid array but the single 1Gb ethernet port is the limiting factor.

      • by Anonymous Coward

        Unless you've got a 10GE client, it would be far more cost effective to add a few 1Gbps ports to your server and bond the interafces. There are lots of cheap Gbit switches capable of LAG/LACP and any server OS should be capable.

    • That's cuz you're not doing it right. Having dual 10GbE ports on each end will let you run SMB3 Multichannel [microsoft.com] for network transfer speeds that will outpace anything but the fastest RAID arrays. We're seeing real-world file transfer speeds of over 1.3 gigabytes (not gigabits) / second over copper Ethernet. I'm seldom a Microsoft advocate but it is awesome.
      • by jon3k ( 691256 )
        There's lots of ways to aggregate multiple NICs (ie LACP). It's very easy to bond multiple 10Gb ports to increase bandwidth. And I've gotten comfortably over 1GB/s over a single 10Gb NIC.
        • SMB3 Multichannel isn't the same as link aggregation. It assigns CPU cores to process SMB transfers as they come across the wire(s), thereby handling one of the real-world bottlenecks (i.e., that the client typically chokes trying to process all of that inbound data coming off of the fast pipe).
        • LACP doesn't actually increase bandwidth. Each host combination only talks to one port. At no point will any IP connection between those hosts go faster than 10gb.

          LACP will let multiple ports talk to multiple other machines with one IP and load splitting (its not balancing since its static mapping) across the LACP group. Its barely more useful than round robin DNS, and you'll lose any advantage from protocols that support multiple links, like iSCSI or SMB3.

Note that in relatively recent developments a wave of PHYs have come about that significantly improve that, but it's still pretty big.

        Now using DACs should bring the power complaint in line with infiniband, though the runs can't be very long by comparison, but then again 'cheap' Infiniband cables can't be that long either (wh

          To put some numbers to it
          Cisco 3064 switches:
          3064-X 64 ports of DAC @ 143W = 2.2W per port
          3064-T 48 ports of GBaseT and 4 SR4 uplinks @362W = 7W per port

          Brocade 6740 switches:
          Brocade VDX 6740 48 ports of DAC and 4 ports of 40Gb QSFP @ 110W = 2.1W per port
          Brocade VDX 6740T 48 ports of 10GBaseT and 4 ports of 40Gb QSFP @ 460W = 8.8W per port

          24x7 operation at $.10/kw ~= $1/W/year so each port of 10GBaseT costs you ~$9-13/year (two sides to the link) over DAC, that would eat up the cable savings pretty fast. Ad

      Look into 10Gb of direct attach copper SFP. Low power and low port cost (at least compared to Infiniband).

      10Gb port costs have come WAY down because of all the competition in the space (read: Arista) fighting with the established players (Cisco, Juniper). You can get a 48 port SFP based Nexus 9732PQ for around $13k (with multiple quad SFP ports). You don't need optics because you just use direct attached cables. Dual port 10Gb SFP based Intel NICs are around $300 now.

I have several Bulldozer based machines, and when built they were a good balance of performance for price, but no more. They are really starting to show their age. They have always been spanked by i5 and above Intels, and as new intels continue to come out, prices on one or 2 generation back intels get better and the price difference ceases to be an issue.
