HyperIP Series – You Asked About Enabling Centralized Remote Backup

Posted by Marketing

A successful remote backup and recovery process depends on the right backup applications, the right management of those apps, and the network to support it. How can HyperIP WAN optimization virtual appliance enable this? Let’s look at a typical remote backup solution consisting of remote servers, residing in a branch, and a central repository of data for the backups, residing in a data center. These servers, virtualized in most cases, require remote backups to occur in a given backup window for each server. These backups are slave to the size of the WAN bandwidth to/from the branch. To reduce the backup windows or at worst, meet them, the WAN overhead has to be eliminated.

Typically, TCP overhead limits actual application throughput over these WAN links. The table below shows anticipated application throughput with HyperIP. Compare this to what you get now and the value proposition of HyperIP becomes evident.

HyperIP mitigates the effects of packet loss, latency, and out of order packets to more effectively drive near wire speed of the WAN link (~95%). Then, if needed, block-level compression, a feature of HyperIP, is applied to further reduce the amount of data traveling over the WAN link, dramatically increasing application throughput. This effectively turns the WAN into LAN-like performance from the backup client to the backup server destination.

Oh Canada, Bandwidth is Expensive – Eh?

Posted by Marketing

Recently a customer brought it to our attention that unlimited bandwidth pricing in Canada is up to 90 times more expensive than other countries.

“Despite Canadians ranking 33rd in broadband Internet speeds worldwide (speedtest.net), Canadian carriers cry foul; their networks are congested and unable to cope with the sheer volume of data that Canadians are consuming,” says the writer, Chris Stavropoulos.

In Japan, England, and the U.S, carriers provide account options for unlimited bandwidth. In Canada, there may be a standard rate for usage of 300 GB per month, with a per-GB charge for overage – an example of usage-based billing. Some Canadian DSL providers cap their overage fees, others do not. The article states cable internet providers are expected to adopt this same usage-based pricing model sometime this year.

In Africa, bandwidth prices remain high because of the expense of deploying necessary infrastructure (satellite versus Fibre optics), complicated and bureaucratic licensing policies, and profiteering.

For data-heavy operations like EMC SRDF, Celerra/Centera, NetApp SnapMirror, Symantec Volume Replicator, Dell EqualLogic, Veeam Backup & Replication, standard file sharing protocols like File Transfer Protocol (FTP), and many others, usage-based billing would quickly add up.

WAN optimization cuts bandwidth costs and resource consumption with minimal effort. Global users can reduce infrastructure costs and alleviate bandwidth constraints without sacrificing service quality, reliability or performance. For some service providers, savings are in the millions of dollars.

Compression is another way to significantly increase effective data throughput and save on overage costs. Compression ratios depend on the type of data that is being compressed. Production results have demonstrated a range of 2:1 up to 15:1. HyperIP WAN Optimization virtual appliance compresses data blocks (versus TCP packets) and efficiently aggregates data into blocks, before moving over the WAN. This puts more data into the HyperIP accelerated WAN. HyperIP’s block level compression feature is very effective, even at speeds up to OC3 (155 Mbps).

Since HyperIP WAN Optimization virtual appliance increases effective data throughput 3 to 10 times, organizations can get increased performance without increasing their usage of bandwidth. Simply put, it takes less bandwidth to replicate data with HyperIP than without it. Even in Canada.

On the Road to a Cloudy World

Posted by Marketing

Recently we wrote about WAN optimizers becoming indispensable for cloud applications like backup/replication and disaster recovery.

In the past year we’ve watched a significant number of companies emerge to provide cloud services for a variety of applications that vary in scope and nature. More and more cloud users expect quick storage access from their mission critical data from remote networking architectures, including the ability to replicate and restore data when needed. This is not always possible because of the same network issues that can slow down recovery of secondary data: bandwidth restrictions, network latency, jitter, packet loss, bit errors, poor line quality and network errors.

Yes, clouds offer many benefits, including a theoretically limitless capacity and scalability, elimination of hardware acquisition and infrastructure expansion costs, the ability to budget for future growth, even the conversion of capital expenses into operating expenses. But for cloud applications to reach their true potential, they need to deal with network latency to deliver on throughput and performance. This is especially true for bandwidth intensive applications. In other words, data needs to be at the right time and right place for clouds to be effective.

We’d like to hear from companies using cloud services on their existing IP networks that are willing to evaluate HyperIP in their environment. You will see firsthand the performance improvements delivered by HyperIP that are compelling to your business.
