Product Flash – Bridgeworks Potomac 40Gb iSCSI-to-SAS Bridge

Written By: Erin Filliater, Enterprise Market Development Manager

 

The amount of worldwide digital information is growing on a daily basis, and all of that data has to be stored somewhere, usually in external storage infrastructures, systems and devices.  Of course, in order for that information to be useful, you need to have fast access to it when your application calls for it.  Enter Bridgeworks’ newest bridging product, the Potomac ESAS402800 40Gb iSCSI-to-SAS protocol bridge.  The first to take advantage of 40Gb/s data center infrastructures, the ESAS402800 integrates Mellanox 40Gb iSCSI technology to provide the fastest iSCSI SAN connectivity to external SAS devices such as disk arrays, LTO6 tape drives and tape libraries, allowing data center administrators to integrate the newest storage technologies into their environments without disrupting their legacy systems.

In addition to flat-out speed, plug n’ play connectivity and web-based GUI management make the ESAS402800 easy to install and operate.   Adaptive read- and write-forward caching techniques allow the ESAS402800 bridge to share storage effectively in today’s highly virtualized environments.

 

All of this adds up to easier infrastructure upgrades, more effective storage system migration and realization of the full performance potential of new SAS-connected storage systems. Pretty impressive for a single device.

RDMA – Cloud providers “secret sauce”

Written By: Eli Karpilovski, Manager, Cloud Market Development

 

With expansive growth expected in the cloud-computing market, some researches expects the market will grow from $70.1 billion in 2012 to $158.8 billion in 2014 – cloud service providers must find ways to provide increasingly sustainable performance. At the same time, they must accommodate an increasing number of internet users, whose expectations about improved and consistent response times are growing.

 

However, service providers cannot increase performance if the corresponding cost also rises. What these providers need is a way to deliver low latency, fast response, and increasing performance while minimizing the cost of the network.

 

One good example to accomplish that is RDMA, Traditionally centralized storage was either slow or created bottlenecks and deemphasized the need for fast storage networks. With the advent of fast solid state devices, we are seeing a need for a VERY fast and converged network, to leverage the capabilities that is been offered, in particular, we are starting to see cloud arch using RDMA based storage appliances to accelerate access storage time, reduce latency and achieve the best CPU utilization on the end point.

 

To learn more about the usage of RDMA in providing cloud infrastructure requirements for meeting performance, availability and agility needs, now and in the future check the following link.
