MailHippo Adopts SIOS DataKeeper Cluster Edition

SIOS Technology Corp. announced that MailHippo, Inc., a company that enables healthcare providers to send and receive encrypted HIPAA compliant emails and to collect medical data using HIPAA compliant Web forms, is using its DataKeeper Cluster Edition to protect their critical secure email platform from downtime and disasters.

Secure information transmission is essential to healthcare providers. From accessing patient test results and medical images to sharing doctor’s notes and health records, quality healthcare requires the ability to manage and transmit health information. However, many organizations face the challenges of doing so while complying with the Health Insurance Portability and Accountability Act (HIPAA), which requires them to ensure confidentiality, integrity and security of any electronically stored, protected health information (known as “ePHI”).

“When protecting mission-critical applications, companies like MailHippo face the challenge of delivering HA and DR to ensure 24/7 uptime,” said Margaret Hoagland, VP, global sales and marketing. “SIOS eliminates this challenge by providing flexible, straightforward HA and DR solutions that protect applications both on-premises and in the cloud, ensuring compliance with even the strictest compliance regulations.“

Challenge: Cost-effective HA for SQL Server
MailHippo’s business-critical encrypted email platform runs on SQL Server 2016 instances in 2 geographically separated, on-premises data centers. The company needed a robust HA and DR (HA/DR) solution to protect the SQL Server database that their mission-critical applications run on.

“Our medical provider customers expect their HIPAA compliant email to be available 24/7,” said Chris Almond, CEO, MailHippo. “Their information is essential to their ability to provide vital health services to their patients.“

The company considered using Windows Server Failover Clustering (WSFC) and SQL Server Enterprise Edition with Always On Availability Groups to add HA protection. However, they did not want the cost and complexity of purchasing and managing the shared storage required by this solution, which would also introduce the risk of a single point of failure.

“We needed an affordable, reliable solution that would allow us to use SQL Server Standard Edition,” said Almond.

They also wanted to leverage their 2 on-premises data centers running across different geographic regions to provide DR protection.

Solution: SANless HA and DR
After research of HA/DR products, MailHippo decided to build a 2-node cluster using SQL Server Standard Edition Always On Failover clustering in one data center and a third node in their second data center for DR. By adding DataKeeper Cluster Edition to their WSFC, the company could replicate local storage on the primary cluster node synchronously to the 2nd node and asynchronously to the 3rd node.

With this cluster configuration, if a SQL Server failure on the primary cluster node is detected, operation is automatically moved to the secondary node and operation continues. Since DataKeeper synchronizes local storage on both primary and secondary nodes, operation can continue with an RPO of zero. In the event of a site-wide disaster, operation can be switched to the DR site.

“The tight integration with WSFC was one of the key reasons we chose SIOS,” said Almond. “We used WSFC to create the clusters for our SQL Server environment just like a traditional cluster, and we simply addednDataKeeper Cluster Edition. This lets us use local storage without the need for a costly SAN.“

SIOS software uses performance-optimized host-based, block-level replication to synchronize local storage on the primary and standby nodes in the cluster, creating storage that appears to the WSFC as a SAN.

Results: Fast and Reliable Failover
MailHippo has been using SIOS SANless clusters and achieving HA and disaster protection. By using SANless clusters, it also eliminated the single point of failure risk of a shared storage cluster.

“DataKeeper is a great fit for a rapidly growing company like ours. It‘s easy to use, cost-efficient and most of all, reliable,” added Almond.

The SIOS system was put to the test in a recent downtime incident.

“We lost our primary SQL Server when both power supplies failed,” said Almond. “But thanks to SIOS, we were able to get the platform back online quickly. Without DataKeeper, we would have required many hours and a mountain of manual work to recover everything. DataKeeper saved us from becoming non-operational.“
