In the IBM Thought Leadership Whitepaper, 10 Ways to Save Money with IBM TSM, “IBM Tivoli Storage Manager Suite for Unified Recovery simplifies and streamlines storage management, helping organizations control both the risks and costs of data protection and recovery.” This blog post visits the savings NetEx’s HyperIP offers by running TSM Replication, a feature of Tivoli Storage Manager Extended Edition and Tivoli Storage Manager Suite for Unified Recovery, over the WAN.

Previous blog posts talk about the performance improvement of TSM replication over HyperIP (http://www.netex.com/blog/?p=206). The following chart describes the true performance of replication over HyperIP (data provided by NetEx):

HyperIP enables TSM replication to see near wire speed, over any distance, even over lossy WANs. With HyperIP’s block level compression, throughput can literally exceed wire speed by as much as 6x; with lossy WANs, over 12x. This means a replication window that moves GB’s of data can be reduced from hours to minutes, without having to increase the bandwidth of the WAN links between remote TSM server nodes. Bandwidth savings alone can return the HyperIP investment in less than 3 months.

Continuation of TSM 6.3 Replication testing over HyperIP

Posted by Marketing

We recently had an opportunity to test IBM Tivoli Storage Manager (TSM) release 6.3 replication in our HyperIP lab. IBM just released this feature as part of their TSM 6.3 release in November. As stated in our previous Blog entry about TSM Backup testing, http://www.netex.com/blog/?p=175, it is important to first determine the overall limits of the native application before WAN acceleration.

Our test configuration included two HyperIP WAN Optimization virtual appliances, two windows servers running TSM 6.3, and a distance simulator for the WAN. The WAN simulator has the ability to inject packet loss, network latency, and other network conditions over various bandwidths that can degrade replication performance.

Like many other applications, replication is designed for the datacenter – to – datacenter movement of corporate data. Most replication applications perform very well when moving data over short distances, or in a metro environment. Customers running TSM Replication, in many cases, will need the remote site to be extended over the WAN, to an internal DR site, DR Service Provider, or Cloud Storage Provider. Any time distance is needed, network conditions such as latency and packet loss can significantly degrade application performance and become a huge impact on the throughput and application efficiency.

In our lab when latency and packet loss is experienced TSM native replication performance slowed by over 80% due to the typical inefficiencies of the TCP transport and not necessarily the fault of the TSM application. When HyperIP was added to the configuration, TSM Replication was able to achieve throughput equivalent to native performance and no delay. In fact HyperIP was able to help TSM Replication achieve near native line speeds at distances represented by 40 ms RTT, 80 ms RTT, 320 ms RTT all the way up to a 1 second RTT. TSM Replication over HyperIP proved to perform quite well at any distance, even with a significant amount of packet loss. In some cases HyperIP will accelerate TSM Replication by 6X. If 2:1 compression is possible then the TSM acceleration with HyperIP may approach 12X. Check it out for yourself. Download HyperIP by clicking on the big orange box above.

A Blog about a Blog, Is that Allowed?

Posted by Marketing

This weeks blog is about a blog post by Justin Paul, a systems engineer from SMS proTech who focuses on virtualization, storage, and backup applications.

Justin was recently working with a customer who was trying to replicate large amounts of data with limited replication windows and a limited amount of bandwidth.  The customer was using Veeam’s Backup & Replication software.

The big question they were confronted with was whether to add more bandwidth to meet the increasing data demands of replication or as an alternative leverage a WAN Optimization solution with the Veeam application in order to better utilize the existing WAN infrastructure.

Fortunately for the customer, they decided to try HyperIP WAN Optimization Virtual Appliance software with Veeam’s Backup & Replication software. The results speak for themselves.

Here’s a link to Justin’s IT Blog post, we thought it was well written and very informative.

Justin blogs are personal in nature and do not reflect the views of SMS proTech.   Can’t be all that bad for a guy who collects vintage Mustang cars, makes his own beer and is not a stranger to putting in long hours and hard work. Here’s more about Justin’s Bio.

We appreciate the blog….

When gambling many times the River Card does not help ….

Posted by Marketing

An enterprise online gaming company uses HyperIP WAN Optimization virtual appliance for global replication acceleration. The company started off using the HyperIP appliance, liked it so much that they migrated to the virtual version of HyperIP which in their environment runs on VMware ESXi. For them, the HyperIP WAN Optimization virtual appliance solution is very cost effective, very easy to implement and provides the ability to scale with software as transfer requirements increase. Everybody likes a little investment protection, right?

So what problem was this company trying to solve? Like many other global enterprises they were challenged with their disaster recovery processes. They used the public internet to move terabytes of data during replication but found it increasingly difficult to meet recovery time objectives as mandated by their disaster recovery plans. The public internet was much less expensive than dedicated circuits but was hampered by latency, packet loss and out of order issues. The company also wanted to reduce their transfer windows, and at the same time deliver more efficient use of current WAN resources, and control bandwidth costs.

The customer uses EMC SRDF/A between sites and added Oracle DataGuard as a second replication application between sites. They tested Oracle DataGuard without informing anyone from NetEx and as expected, HyperIP worked like a charm. The point is, it is pretty easy to add additional applications to operate with HyperIP.

Did the customer try any other WAN Optimization solutions? Yes they tried Riverbed Steelhead appliances but decided to keep using HyperIP because of the significant performance advantage and the cost effectiveness of the software solution.

At the end of the day HyperIP helped this online gaming customer reduce replication, backups and migrations time frames by as much as 60%. The fact that HyperIP was a VMware Ready solution is extremely important to this customer. With a HyperIP WAN Optimization virtual appliance solution the customer is happy with the ease of deployment, lost cost, ease of support and maintenance, ease of integration into their existing virtual environment, including the speed of deployment of newly created virtual machines.

This customer is very satisfied with their HyperIP WAN Optimization virtual appliance solution.

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.

HyperIP WAN Optimization Virtual Appliance Solves Key Network Issues for Dell EqualLogic Replication

Posted by Marketing

A customer was recently experiencing slow replication of their databases using a Dell EqualLogic Replication application from their iSCSI SAN. They were concerned about replication windows so decided to research performance on the Dell website. In their investigation they found the following document on the Dell website.

Using Dell EqualLogic Auto Replication

This document explains use case scenarios and various configuration issues of Dell EqualLogic Replication in a typical DR scenario. A couple of the main network considerations when implementing Dell EqualLogic Auto Replication should be bandwidth and latency of the circuit. In high latency connections, replication will still work, but allow more time to complete. This is sound advice. From our experience, packet loss can also have a huge impact on application throughput.

HyperIP WAN Optimization virtual appliance, when configured with EqualLogic Replication, can reduce bandwidth requirements for replication by over 50% while maintaining high throughput. This brings the windows for replication into minutes instead of hours, allowing for the ease of testing the recovery plan, as well as recovering a node, server, cluster, or the entire site’s data volumes after a true disaster.

Simply, your current benchmark or replication assessment must take into consideration the average available bandwidth on a link with any packet loss or latency can be reduced to 40%-60%. HyperIP accelerates applications over WANs by time of day, to nearly 95% utilization. With a combination of block level compression, latency and packet loss mitigation, HyperIP can then improve EqualLogic replication throughput by 3X-6X .

Check out this TechValidate case study from one of our customers who uses Dell EqualLogic Replication and HyperIP. Click here to see case study.

Nothing Like a Tasty Hot Dog at the Ballpark…

Posted by Marketing

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.

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.
