Just Punch It:  Accelerating Storage the Easy Way

Architecting storage solutions means being on the hunt for bottleneck after bottleneck and removing them to eliminate latency wherever possible. With the availability of storage media such as Flash and high-performance disk drives, the bottleneck has often moved away from the storage medium itself and onto the interconnect.

 

When building our enterprise storage as a service offerings, we’ve had to overcome several bottlenecks – from reinventing the proprietary, purpose-built controllers of traditional arrays that caps the speed and expandability of an array, through the performance of the controllers, to using flash cache acceleration, it was clear that to deliver applications with even better efficiency our award-winning Virtual Private Storage Arrays (VPSA) need to take advantage of new technologies for the datapath.

 

What is iSER technology?

iSER is an interface that uses Ethernet to carry data directly between server memory and storage devices. The protocol eliminates memory copies (a.k.a. memcpy) and the operating system TCP/IP stack, and bypasses the CPU of the target system entirely.  As such, it is lossless, deterministic, with low overhead, and delivers far better CPU efficiency by freeing up resources.

End of an Era: OEM Dominance – Could it Be a Thing of the Past?

Guest Blog post by Giacomo Losio, Head of Technology – ProLabs

Original equipment manufacturers (OEM’s) have long dominated the optical components market but a new study now suggests that, as a result of tighter margins and greater competition, customers are putting quality and price before brand.  Is the era of the big OEM at an end?

When asked their views of the optical transceiver market at the European Conference on Optical Communications (ECOC) in Cannes, over 120 attendees revealed a trend which indicates a paradigm shift in attitudes.

Why do they buy? What they buy? What keeps them up at night? The answers may surprise you:

  • 98% of respondents ranked quality as one of their top three priorities when purchasing fibre optics
  • 89% of respondents placed price in the top three list of priorities
  • Yet only 14% of respondents even considered brand names to be a top three priority – or even a concern

The Benefits of Leaning Into the Big Data

Guest post by Alex Henthorn-Iwane, QualiSystems

Big data is for real, but its places heavy demands on IT teams, who have to pull together and provision cloud infrastructure, then offer big data application deployments with validated performance to meet pressing business decision timelines.  QualiSystems is partnering with Mellanox to simplify big data deployments over any cloud infrastructure, enabling IT teams to meet line of business needs while reducing operational costs.

The Storage Fabric of the Future Virtualized Data Center

Guest post by Nelson Nahum, Zadara Storage

It is evident that the future data center will be based on cutting-edge software and virtualization technologies to make the most effective use of hardware, compute power, and storage needs to perform essential analytics and to increase the performance of media-related and advanced web applications. And it turns out that the wires that will connect all this technology together are no less crucial to next-generation data centers and clouds than the software and virtualization layers that run within them.


There are multiple storage fabrics and interconnects available today, including Fibre Channel, Ethernet and SAS. Each has various pros and cons, and fabrics were chosen according to need of performance, compatibility and cost efficiencies.

 

As an enterprise storage as-a-service provider, delivering a software-based cloud storage solution for public, private and hybrid cloud models based on commodity hardware, Zadara Storage provides storage as-a-service in multiple public cloud and colocation facilities around the globe. Consistency, high availability and predictability are key in supplying the scalable, elastic service our customers expect, regardless of their location, facility or the public cloud they employ. The hardware we use needs to be dependable, pervasive and cost-efficient in order to sustain the performance and cost-level of our service, anywhere and at any scale.

 

When choosing our fabric, Ethernet came as a clear choice. Ethernet is likely to become the new standard, and boasts several advantages vital to our product:

  • Ethernet’s speed roadmap is aggressive: from 10GbE to 40GbE, and upcoming 100GbE
  • Ethernet is ubiquitous: we can employ it with no complication at any data center or colocation facility around the globe
  • The latency we have found to be more than manageable, specifically as we use advanced techniques such as IO virtualization and data passthrough
  • Ethernet is the most cost effective: an as-a-service company needs to have a competitive pricing edge.

The future of enterprise storage
The future of Enterprise Storage lies in software and a choice of hardware (premium or commodity). Software-defined storage can scale performance more easily and cost effectively than monolithic hardware, and by combining the best of hardware of software, the customer wins. Ethernet is a critical element of our infrastructure, and Mellanox switches offer significant higher performance and consistent dependability that enables our storage fabric and meets our customer’s needs.
