The Mellanox SX1018HP is a game changer for squeezing every drop of latency out of your network

Guest blog by Steve Barry, Product Line Manager for HP Ethernet Blade Switches

One of the barriers to adoption of blade server technology has been the reliance on a limited number of network switches available.  Organizations requiring unique switching capabilities or extra bandwidth have had to rely on Top of Rack switches built by networking companies that have little or no presence in the server market. The result was a potential customer base of users who wanted to realize the benefits of blade server technology but were forced to remain with rack servers and switches due to a lack of alternative networking products. Here’s where Hewlett Packard has once again shown why they remain the leader in blade server technology by announcing a new blade switch that leaves the others in the dust.

Working closely with our partner Mellanox, HP has just announced a new blade switch for the c-Class enclosure that is designed specifically for customers that demand performance and raw bandwidth. The Mellanox SX1018HP is built on the latest SwitchX ASIC technology and for the first time gives servers a direct path to 40Gb. In fact this switch can provide up to sixteen 40Gb server downlinks and up to eighteen 40Gb network uplinks for an amazing 1.3Tb/s of throughput. Now even the most demanding virtualized server applications can get the bandwidth they need. Financial service customers and especially those involved in High Frequency Trading look to squeeze every drop of latency out of their network. Again, the Mellanox SX1018HP excels, dropping port to port latency to an industry leading 230nS at 40Gb. There is no other blade switch currently available that can make that claim.

For customers currently running Infiniband networks, the appeal of being able to collapse their data requirements onto a single network has always been tempered by the lack of support for Remote Direct Memory Access (RDMA) on Ethernet networks. Again, HP and Mellanox lead the way in blade switches. The SX1018HP supports RDMA over Converged Ethernet (RoCE) allowing those RDMA tuned applications to work across both Infiniband and Ethernet networks. When coupled with the recently announced HP544M 40Gb Ethernet/FDR Infiniband adapter, customers can now support RDMA end to end on either network and begin the migration to a single Ethernet infrastructure. Finally, many customers already familiar with Mellanox IB switches provision and manage their network with Unified Fabric Manager (UFM). The SX1018HP can be managed and provisioned with this same tool, providing a seamless transition to the Ethernet word. Of course standard CLI and secure web browser management is also available.

Incorporating this switch along with the latest generation of HP blade servers and network adapters now gives any customer the same speed, performance and scalability that was previously limited to rack deployments using a hodgepodge of suppliers.   Data center operations that cater to High Performance Cluster Computing (HPCC), Telecom, Cloud Hosting Services and Financial Services will find the HP blade server/Mellanox SX1018HP blade switch a compelling and unbeatable solution.

HP is the first to provide 40Gb downlinks to each blade server enabling InfiniBand-like performance in an Ethernet blade switch. Another industry first, the low-latency HP SX1018 Ethernet Switch provides the lowest port to port latency of any blade switch, more than four times faster than previous switches

 

When combined with the space, power and cooling benefits of blade servers, the Mellanox SX1018HP Ethernet Blade Switch provides the perfect network interface for Financial applications and high performance clusters.

 

Why I left HP after 19 years to join ProfitBricks

On 02.12.13, In Cloud Computing, by

Pete Johnson, new Platform Evangelist

Woz once said, “I thought I’d be an HPer for life.” While I don’t usually claim to have a whole lot in common with the man who designed the first computer I ever saw (an Apple II, summer ’78), in this instance it’s true. As it turns out, we were both wrong.

Pete Johnson, new Platform Evangelist for ProfitBricks

I stayed at HP as long as I did for lots of reasons. Business model diversity is one:  over the last two decades, I was lucky enough to be a front line coder, a tech lead, a project manager, and an enterprise architect while working on web sites for enterprise support, consumer ecommerce sales, enterprise online sales, all forms of marketing, and even post-sales printing press supplies reordering.   Most recently I was employee #37 for HP’s new public cloud offering where I performed a lot of roles including project management of web development teams, customer facing demonstrations at trade shows, and sales pitches for Fortune 500 CIOs.  But I also remained at HP because of the culture and values that came straight from Bill Hewlett and Dave Packard, which my early mentors instilled in me. You can still find those values there today if you look hard enough, and if anybody gets that, Meg Whitman does.

Why leave HP for ProfitBricks then?

So if I still have such a rosy view of HP, despite recent bumpiness, why did I leave to become the Platform Evangelist for ProfitBricks?

Three reasons:

  1. InfiniBand
  2. InfiniBand
  3. InfiniBand

If you are anything like the sample of computer industry veterans I told about my move last week, you just said, “What the heck is InfiniBand?” Let me explain what it is and why it is poised to fundamentally change the cloud computing.

Ethernet is the dominant network technology used in data centers today. Originally created during the Carter administration, it uses a hierarchical structure of LAN segments, which ultimately means that packets have exactly one path to traverse when moving from point A to point B anywhere in the network. InfiniBand, which is a popular 21st century technology in the supercomputing and high-performance computing (HPC) communities, uses a grid or mesh system that gives packets multiple paths from point A to point B. This key difference, among other nuances, gives InfiniBand a top speed of 80 Gbits/sec, resulting in a speed that is 80x faster than Amazon’s AWS 1Gbit/sec standard Ethernet connections.

What’s the big deal about InfiniBand?

“So what?” you may be thinking. “A faster cloud network is nice, but it doesn’t seem like THAT big a deal.”

Actually, it is a VERY big deal when you stop and think about how a cloud computing provider can take advantage of a network like this.

As founder and CMO Andreas Gauger put it to me during the interview process, virtualization is a game of Tetris in which you are trying to fit various sizes of Virtual Machines on top of physical hardware to maximize utilization. This is particularly critical for a public cloud provider. With InfiniBand, Profit Bricks can rearrange the pieces, and at 80 Gbits/sec, our hyper-visor can move a VM from one physical machine to another without the VM ever knowing. This helps us maximize the physical hardware and keep prices competitive, but it also means two other things for our customers:

  • You can provision any combination of CPU cores and RAM you want, up to and including the size of the full physical hardware we use
  • You can change the number of CPU cores or amount of RAM on-the-fly, live, without rebooting the VM

In a world where other public cloud providers force you into cookie cutter VM sizes in an attempt to simplify the game of Tetris for themselves, the first feature is obviously differentiating. But when most people hear the second one, their reaction is that it can’t possibly be true — it must be a lie. You can’t change virtual hardware on a VM without rebooting it, can you?

No way you can change CPU or RAM without rebooting a VM!

Do you suppose I’d check that out before leaving the only employer I’ve ever known in my adult life?

I spun up a VM, installed Apache, launched a load test from my desktop against the web server I just created, changed both the CPU Cores and RAM on the server instance, confirmed the change at the VM command line, and allowed the load test to end.  You know what the load test log showed?

Number of errors: 0.

The Apache web server never went down, despite the virtual hardware change, and handled HTTP requests every 40 milliseconds. I never even lost my remote login session. Whoa.

But wait, there’s more (and more to come)

Throw in the fact that the ProfitBricks block storage platform takes advantage of InfiBand to not only provide RAID 10 redundancy, but RAID 10 mirrored across two availability zones, and I was completely sold.  I realized that ProfitBricks founder, CTO, and CEO Achim Weiss took the data center efficiency knowledge that gave 1&1 a tremendous price advantage and combined it with supercomputing technology to create a cloud computing game-changer that his engineering team is just beginning to tap into. I can’t wait to see what they do with object storage, databases, and everything else that you’d expect from a fully IaaS offering. I had to be a part of that.

Simply put: ProfitBricks uses InfiniBand to enable Cloud Computing 2.0.

And that’s why, after 19 years, I left HP.
