VI Briefing: Cayan Protects Business Critical Applications with SIOS SANLess Clusters

Easy-to-Manage High Availability Protection for Business Critical SQL Server

SAN MATEO, CA – February 18, 2015 – SIOS Technology Corp. (www.us.sios.com), maker of SAN and #SANLess clustering software products, today announced that Cayan™ is using SIOS DataKeeper™ Cluster Edition software to protect its important Windows applications.

Cayan is the leader in the payment solutions industry. The company’s flagship Genius® Customer Engagement Platform® aggregates and integrates every conceivable transaction technology, payment type and customer program – both present and future – into a single platform. Customers include some of the world’s largest online retailers. “Our top priority is ensuring that our customers can complete transactions continuously 24 hours a day, seven days a week,” said Paul Vienneau, chief technology officer, Cayan.

When the company decided to move to a larger, state-of-the-art data center, they looked for an affordable, easy-to-deploy way to provide high availability and disaster protection for the SQL Server database that their Genius platform and other important applications run on. The company considered using a traditional shared storage cluster, but did not want the cost and complexity of purchasing and managing a SAN storage array. As shared storage, a SAN would also introduce the risk of a single point of failure. “We needed a solution that could handle the large volume of transactions we process without slowing application performance,” said Vienneau.

Cayan IT staff decided to use SANLess clusters. They built two-node clusters using standard Windows Server Failover Clustering (WSFC) and adding SIOS DataKeeper Cluster Edition software as an ingredient. “The SIOS software has very intuitive configuration wizards that enabled us to deploy our platform and applications in the SANLess clusters quickly and easily,” said Vienneau. “Since SIOS DataKeeper is completely integrated with WSFC, our IT staff did not have to change system administration or add complexity.”

Because the SANLess clusters use local storage, there is minimal performance overhead and fast application response times. “We were able to run our applications in the new SANLess cluster environment in our new data center in a full production mode before we put it into full production. We set up a performance lab and tested the replication latency under heavy load. It ran great. The SIOS software met or exceeded our expectations. Implementation and ongoing administration is easy and we have had zero downtime since we implemented our SIOS SANLess clusters,” said Vienneau.

“Results achieved by Cayan are common across SIOS’ customer base,” said Jerry Melnick, COO, SIOS Technology. “SIOS DataKeeper adds replication for disaster protection in SAN-based Windows clusters and enables SANLess clusters in Windows Server Failover Clustering environments where shared storage clusters are impossible or impractical.”

Tech Target – Search Disaster Recovery: Cayan DR goes ‘from zero to 60’ with DataKeeper SANless mirror

February 12, 2015 by Margaret Hoagland

Using DataKeeper software, Online transaction processing firm Cayan sets up mirror sites for ‘quasi active-active’ servers that facilitate rapid failover.

Online credit card transaction company Cayan set up effective disaster recovery/high availability using only its Windows Server and DataKeeper software or for asynchronous replication between two sites.

Boston-based Cayan, which changed its name from Merchant Warehouse in January, helps companies complete customer transactions through options such as online purchases, mobile payments and ApplePay.

Cayan’s business requires that it stay online without exception, so high availability is as important as recovery from a large disaster. The firm uses Microsoft Windows Server as storage for the SQL database that its customer engagement system runs on. After experimenting with Microsoft’s native replication but finding it to be too much work, Cayan avoided buying a SAN by installing SIOS Technologies DataKeeper Cluster Edition software. DataKeeper works with Windows Server Failover Clustering (WSFC) to protect data through real-time block-level replication.

Cayan began testing DataKeeper in late 2013 and put it in production in 2014. At the time, it added a co-location site provided by CenturyLink as part of a data center upgrade. The company uses DataKeeper to asynchronously replicate between databases at its Waltham, Massachusetts, facility and a mirror colocation site in Oak Grove, Illinois.

The secondary site is passive, but Cayan is testing what CTO Paul Vienneau calls a “quasi active-active” setup for load balancing, enabling live traffic at both sites. The database node will be active at one site, and all traffic will go to that site. If the active site goes down, its SQL Server node will fail over to the other site in less than a minute, Vienneau said.

“If the primary database node is in Waltham, the traffic that goes into Oak Grove will be re-directed from the application servers that sit in Oak Grove across the WAN to the database server in Waltham,” Vienneau said. “That gives us minimal [recovery time] there as far as getting back up. If there’s a disaster scenario in Waltham, the SQL server failover will take in 30 seconds and we’ll be live in the Oak Grove site. Because both sites are quasi-active, there’s not a lot of heavy lifting other than the database failing over, and away we go.”

Vienneau said Cayan is in the final stages of testing that setup and will soon go live.

Even without the active-active setup, DataKeeper’s replication makes for quicker recovery than Cayan had before. Vienneau said it could take hours to restore his database the old way when Cayan relied on a Rackspace managed service.

“There wasn’t any of what I call a plausible DR strategy,” he said. “We built this from the ground up when we moved out of Rackspace to CenturyLink. We went from zero to 60 with our HA and DR strategy.”

Vienneau said Cayan hasn’t had any disasters since using DataKeeper but “we’ve tested considerably.”

Vienneau calls his set up high availability instead of only DR “because we can set up fairly quickly in the Oak Grove site, so you can think of it has geo-diverse HA. We have redundancy throughout the entire stack. Because DataKeeper keeps both sites in sync at any point in time and because we can minimize failover, we have two data centers acting as HA.”

“It’s not a traditional DR where your recover time is two hours. It’s taking us less than a minute. We can make it seamless for the end user. They might see a little lag where the cut over is taking place, but they’re not seeing any loss of transactions.”

Those end users consist mostly of small businesses that rely on Cayan to process their credit card transactions.

“We’re a 24/7/365 shop,” he said. “We’re not afforded a lot of downtime. We process over $100 billion in credit card transactions a year. If we’re down a couple of hours, it’s not good for us our merchants.”
