NetEx/IP® and HyperIP® Today

Network Executive Software, Inc. (NESi) brings high performance file transfer technology to the industry-standard IP environment with its NetEx/IP and HyperIP software products.

NetEx/IP is many times faster than TCP over long distances, which makes it the ideal solution for moving massive amounts of mission- or time-critical data across the country or across the globe.  As proven by our long-term users, NetEx/IP has the highest throughput rates over long distances with no degradation of performance because of its efficient bandwidth utilization and mitigation of the effects of packet loss and latency. In fact, NetEx/IP and its predecessor product NetEx/HC (HyperChannel) have provided solutions for moving data for global corporations and US state and government agencies for more than 30 years.

For existing TCP applications, the premier solution is NESi’s low cost HyperIP.  HyperIP transparently implements NetEx/IP in the data path to provide all the NetEx/IP improvements, plus compression of data, on a virtual machine without having to modify existing applications or operating procedures.

The Challenge: Securing the Data

With an increase in hacking and breaches of sensitive databases in recent years, many corporations (especially those in the financial, government, or health sectors) and US government agencies are looking at ways to better protect data transiting between sites and the databases themselves.  Data security is also of utmost importance for those customers utilizing shared/public networks.

NetEx/IP Security Enhancements

NESi recognizes this concern for data protection and is therefore planning to enhance NetEx/IP and HyperIP over the next year with standards-based security technology like Transport Layer Security (TLS) to significantly increase the security of the data being moved across the computer room, the country, or globally.

TLS is a cryptographic protocol that secures data as it is transmitted, focusing on authentication, data integrity, and data confidentiality. With TLS, keys are generated uniquely for each connection and are based on a shared secret negotiated at the start of a session, providing security between two applications using NetEx/IP or HyperIP.  Adding TLS to our NetEx/IP products will also provide improved security for our BFX & PFX utilities, which interface upward to customer applications.

In addition to data security, adaptive block compression of data will also be added to NetEx/IP, thus decreasing WAN bandwidth usage and effectively increasing the application data throughput over the network.

HyperIP Series – You Asked About TSM Testing with HyperIP..

Posted by DaveHuhne

We recently had an opportunity to test IBM Tivoli Storage Manager (TSM) Client to a TSM Server in our HyperIP lab. When doing any kind of application verification or performance testing it is important to first determine the overall limits of the native application with and without WAN acceleration.

Lab testing in an emulated environment is a good way to test applications because you can mimic certain network topologies and characteristics. In our case the HyperIP lab consists of two HyperIP WAN Optimization virtual appliances, two windows servers, and a distance simulator for the WAN. The simulator has the ability to inject packet loss, network latency and other network conditions over various bandwidths that can degrade application performance.

The main objective with any test is to try to validate whether the HyperIP can accelerate the application over various distances with varying latency and packet loss scenarios. Every application has its own performance characteristics and limitations. The same is true for WAN networks. They are about as unique as fingerprints.

Like many backup applications TSM was designed for the data center and performs very well when moving data short distances. Since we are truly becoming a global society is it important to be able to move data over longer distances which is clearly a requirement of cloud storage environments.

With the case of IBM TSM, we started off testing with a simple delay of 10 ms round trip time (RTT). At this relatively short distance TSM slowed by 80% compared to its native performance. This is typical application degradation due primarily to the inefficiencies of the TCP transport and not necessarily the fault of the TSM application. When HyperIP was added to the configuration, the TSM application was able to achieve throughput equivalent to native performance and no delay. In fact HyperIP was able to help TSM achieve near native performance rates at distances represented by 40 ms RTT, 80 ms RTT, 320 ms RTT all the way up to a 1 second RTT. This is a testament to how well TSM and HyperIP interoperate together.

Many applications have internal limitations such as outstanding operations, queue size, or queue depth that artificially restrict the application’s ability to maximize throughput. That was certainly not the case with TSM. TSM can certainly pump data over the network when it is not encumbered with TCP performance issues. When operating TSM with HyperIP, the two combined can sustain the same throughput rates whether running across town, across the ocean, or around the world. That was very impressive. TSM over HyperIP brings LAN-like performance to WAN-based remote backups.

HyperIP Series – You asked about Backup…

Posted by DaveHuhne

Backing up your data to a remote site is a business necessity. The method or design of your backup solution will be dependent on your requirements and whose system you own. Things like backup window, WAN, de-dupe, distance and incrementals all come into play when making purchase decisions for a backup solution. So why do I need a WAN Accelerator? My storage backup system de-dupes and compresses the data before sending it to its remote DR site. If I install a WAN Accelerator will it provide any additional value? Will data be further reduced after dedup and how much will my application throughput increase?

These are great questions but first you will have to determine if there is a bottleneck in your network. My backups don’t complete on time, why? My backup application throughput is low, why? I can only backup certain servers per night or my backup fills the window and I have new servers arriving as we speak. I can’t keep up so what should I do to solve the issue?

I can buy more bandwidth, increase the buffers in my switches, make the TCP windows bigger. Some of these remedies are expensive, take time or maybe I can’t make changes to the network? A plausible alternative is to test a WAN Accelerator.

HyperIP WAN Optimization virtual appliance helps alleviate many network issues that cause poor application performance and throughput over WANs. The software doesn’t care that your backup system data has been prior de-duped and/or compressed. The software uses an adaptive compression algorithm and will attempt to further reduce deduped data if at all possible. Compression is only one feature of the software that improves application performance. TCP transfers will also be affected by any number of network issues including congestion, jitter, latency, and packet loss. A minimal amount of packet loss can reduce effective throughput by half. Any resulting retransmits will further consume your bandwidth into making you believe your WAN utilization is high when in fact you are really only moving a fraction of the real data. HyperIP shields TCP applications from network issues allowing the maximize throughput.

So back to the question “What data reduction will I get with HyperIP”? The answer is HyperIP will manage the network so that the maximum throughput will be achieved as long as the application can deliver the required data to fill the pipe. As an example we have customers whose backup windows have gone from 24+ hours down to single digits. A recent Veeam customer reduced their backup window from 15 hours to 3 hours with HyperIP.

Obviously every backup environment is different but downloading and testing HyperIP for yourself is quick and easy and could save you a lot of time.

Nothing Like a Tasty Hot Dog at the Ballpark…

We love talking about our customer success stories.

Below is a brief success story about Ovations Food Services. They deliver fresh food and beverages to public assembly facilities throughout the United States and Canada. They specialize in providing food services to stadiums, arenas, convention centers, fairgrounds, expo-centers, auto racing, casinos, performing arts centers and amphitheaters.

With multiple locations in North America, Ovations uses Veeam’s Backup & Replication to replicate integral virtual machines between Philadelphia and Tampa, all over a 20 Mb/s WAN. They replicate approximately 10 GB/s daily however at times were seeing replications take over 15 hours to complete for a single virtual machine. Ovations needed help.

The Veeam Backup & Replication application was experiencing degraded performance due to high latency and packet loss on the WAN. Backup windows were difficult to achieve and the WAN was not used as efficiently as it could. Not the fault of the Veeam application.

So what happened?

Ovations was already a Veeam customer and decided to test the HyperIP Virtual Appliance via a 30 day evaluation from the NetEx website; http://netex.com/eval. HyperIP was implemented in a very short period of time and almost instantly Veeam’s Backup & Replication application throughput improved by 7x. This allowed Ovations to reduce their replication window from 15 hours to 3 hours.

Ovations considered WAN optimization solutions from both Blue Coat & Riverbed, but decided their virtual appliance solutions were too expensive and the virtual machine footprints for these solutions required too many system resources when compared to the thin footprint of the HyperIP.

HyperIP exceeded Ovation’s expectations for their replication requirement. Not only is HyperIP aggregating the transfer of Veeam but other important applications as well. HyperIP is great at shielding applications from network issues that would normally degrade transfer performance and throughput.

Another happy HyperIP customer.
