SIOS DataKeeper Cluster Edition Delivers High Availability Protection, Configuration Flexibility, Bandwidth Efficiency

A leading healthcare information services provider serves more than 10,000 healthcare organizations across the United States. They rely on their SQL Server databases to deliver a wide range of services. This includes revenue management, patient self-service, and patient care management systems.

SIOS DataKeeper Cluster Edition eliminated bandwidth issues, improved data protection, and significantly reduced downtime in a critical healthcare network environment.

The Environment

The company has more than 20 SQL Server clusters located in two geographically separated data centers for primary data support and disaster recovery. They also have smaller servers in their network, as well as SQL Server log shipping for disaster recovery. Because of this vast customer base and IT infrastructure, the company needed a secure, reliable High Availability Protection solution. Something that could efficiently handle heavy network traffic, limit the amount of data at risk, and reduce downtime.

The Challenge

Replication to the company’s disaster recovery site flooded bandwidth, which reduced reliability across the entire network. A reliable network is critical for maintaining and processing patient and billing data for the company’s hospital and healthcare provider clients. The company also needed a reliable, efficient High Availability Protection to improve their recovery point objective (RPO). This means that they need to significantly limit the amount of data at risk. RPO is determined by the amount of time between data protection events and how much data could be lost during a disaster recovery. The company sought to improve the recovery time objective (RTO), which is the maximum length of downtime that can be tolerated after a disaster or failure.

The Solution

The company chose SIOS DataKeeper Cluster Edition. But before they deployed it, they ran a proof-of-concept (POC) to ensure it would provide the required functionality. The POC was a stress test on both sides of the network, using very large simulated data files. Throughout the test, the IT staff watched SQL Server failover successfully and resume mirroring in a high change rate environment. Adding Unparalleled Configuration Flexibility, SIOS DataKeeper Cluster Edition software provides efficient host-based, block-level replication to synchronize storage on the SAN with local storage in their DR site. It adds the configuration flexibility to create a Windows Server Failover Clustering environment using your choice of SAN-based, SANless, or hybrid storage. After SIOS DataKeeper Cluster Edition passed the company’s stringent POC testing, they deployed it into their production environment. They created a three-node cluster. Comprising two SAN-based nodes in their primary, on-premises data center and one SANless node in their remote disaster recovery site.

The Results

SIOS DataKeeper Cluster Edition synchronized replication among all three nodes in the cluster. At the same, it eliminated the bandwidth issue at the disaster recovery site. The company saw substantial improvement in both recovery point and recovery time objectives and reduced the cost of bandwidth. The company now uses SIOS DataKeeper to protect their important SQL Server in more than 18 cluster nodes.

ALYN Hospital Ensures High Availability And Disaster Recovery Protection For Its Critical Applications with SIOS DataKeeper

SIOS Chosen for its Cost-effectiveness and Application-agnostic Design

SAN MATEO, CA – March 5, 2019 – SIOS Technology Corp., the industry pioneer in providing intelligent application availability for critical workloads, today announced that ALYN Hospital is using SIOS DataKeeper software to provide high availability and disaster recovery protection for all of ALYN Hospital’s mission-critical applications. This includes electronic medical records, customer relationship management, SQL Server databases, Exchange and Office.

ALYN Hospital is acknowledged worldwide as a premier pediatric rehabilitation hospital in Israel. ALYN specializes in diagnosing and rehabilitating infants, children, and adolescents with physical disabilities, both congenital and acquired.

The IT Department at ALYN Hospital operates a variety of applications in a virtualized Microsoft Windows Server environment. “As a hospital, we are subject to some fairly strict government regulations, so we needed to implement strong business continuity provisions for many of our applications,” explained Uri Inbar, ALYN’s IT Director.

Hyper-V Replica, which is integral to Microsoft’s Hyper-V hypervisor, was an obvious choice for ALYN’s business continuity needs. The IT Department operates two, physically-separated server rooms on premises, which enables all critical virtual machines running on any Hyper-V host server to be replicated to another in the other room. “We were really struggling to satisfy our recovery point and recovery time objectives with this arrangement, so we started investigating other options,” Inbar recalled.

The Evaluation Criteria

To evaluate third-party failover clustering software, Inbar established three criteria: The solution had to work with existing hardware; it had to provide both high availability (HA) and disaster recovery (DR) protections all of the hospital’s critical applications, and the total cost had to fit within the department’s limited budget. The IT staff quickly narrowed the third-party options to two, and after carefully evaluating both, found that only one met all of its criteria: DataKeeper from SIOS Technologies. “While we needed a solution that was cost-effective, we were determined not to sacrifice quality or capabilities,” Inbar emphasized. “With SIOS we found a solution that delivers carrier-class capabilities with a remarkably low total cost of ownership. For us, it was an obvious choice.”

The Results

SIOS DataKeeper is ideal for ALYN Hospital’s needs for high availability and disaster recovery protection. Because it is purpose-built to provide both HA and DR protections in a single, cost-effective solution. The ability to create 3-node SANless failover clusters with a single active and two standby instances has proven to be especially valuable for ALYN’s needs. “We are updating systems and software continuously, and with DataKeeper we can do that without any disruption to operations,” noted Inbar. Because the data replication supports multiple standbys and enables manual, dynamic assignment of the active and standby instances, the active instance can be moved to any server in a 3-node cluster and remain fully protected during periods of planned hardware and software maintenance.

Other SIOS DataKeeper features that are important to ALYN’s needs include the ability to work with any type of storage and WAN-optimized data replication. “The SIOS cluster seamlessly supports any storage volume recognized by Windows, and this substantially simplifies operations while enabling us to utilize all of our storage resources,” Inbar explained. Additionally, the WAN optimization will prove useful as Inbar and his team implement the remote disaster recovery site.

Inbar is confident the SIOS SANless failover cluster will perform as desired when needed: “We test the configuration regularly and routinely change the active and standby designations while redirecting the data replication as needed during planned software updates, and the applications have always continued to run uninterrupted. It just works and that’s very reassuring.”

“Whether your company’s critical applications are operating in a physical server environment, a private cloud, a public cloud or a hybrid cloud, they must be protected from downtime and data loss,” said Jerry Melnick, president and CEO, SIOS Technology. “ALYN is using SIOS to provide a fast, cost-effective high-availability solution for applications in a virtualized environment. I applaud them for their use case and innovation and look forward to continuing to provide value to their HA and DR strategies.”

The effortless way to High Availability Cluster Solution For High Service Level

Improve Ordering Process with High Availability Cluster Solution

The Japan Contact Lens Association has an online ordering system that takes in orders from dealers to manufacturers and agents all year round. SCSK Co., Ltd. (hereinafter referred to as SCSK) manages this system. They added SCSK’s infrastructure cloud service “USiZE Shared Model” with an operating rate of 99.99%. At the same time, they included LifeKeeper to secure a high occupancy rate in the cloud and DataKeeper to build an operational infrastructure with High Availability Cluster Solution. With these softwares, the team could detected abnormalities not only on hardware and virtual machines, and applications. They have set up a system to quickly restore and continue services even in case of a crisis.

Contact Lens Ordering Platform That Provides 24 Hours 365 Days Service To The Cloud

The Japan Contact Lens Association supports the dissemination of contact lenses and the development of the industry. They operate a network system called “CLIOS (Contact Lens Information & Order System)”. “Web-CLIOS” is an ordering system that can easily place orders from web browsers anytime and anywhere.

High Availability Function To Monitor Applications To Minimize Business Impact In Case Of Failure

The USiZE shared model was supposed to be used as a new operational infrastructure of “Web-CLIOS”. It not only provides computing resources, but also provides system operation know-how acquired over 40 years and ITIL. The latter is a best practice in IT service management and a feature that provides high-quality service. However, even this is not perfect. “To realize the service level required by the Japan Contact Lens Association, we needed a mechanism to increase the availability of the application layer,” Mr. Ishihara said. The USiZE shared model is also equipped with high availability function. For example, if a failure occurs in the host server, you can easily move the virtual machine running on it to another healthy host server easily. It can be failed over. However, what can be monitored with the native virtualization infrastructure is only the state of the guest OS. It is impossible to detect failure of the application. Tesio Abe of senior engineer at SCSK cloud service department, explains, “Although the host server and guest OS appear to be operating normally, the application running on it seems to freeze or go down due to some reason. In the case of mission-critical services like “Web-CLIOS”, high availability functions that can monitor applications are essential.”

Short Failover Time With LifeKeeper and DataKeeper

In order to solve this problem, SCSK focused on cloud-ready High Availability Cluster Solution. After comparing and examining products of several vendors, they adopted LifeKeeper. Makoto Nagashima, SCSK Cloud Service Department Foundation Service Manager, said the High Availability Cluster Solution could maintain reliable operation for a long time.

Above all, it is also easy to install. High-speed data mirroring is performed by DataKeeper as a shared storage between the production node and the standby node. Even if abnormality occurs in the production node, LifeKeeper has a mechanism that can fail over in a shorter time which cannot be found with other products.

High Availability Brought About By “Protection Suite” Will Be Their Weapons For the Future

Although more than two years have already passed since the renewal of “Web-CLIOS”, the system infrastructure has continued to operate steadily without causing serious troubles.

SCSK says it will actively utilize “Protection Suite” in other services and projects. Ikeda said, “While high-speed availability of “mission critical “cloud migration is expected to accelerate, LifeKeeper and DataKeeper’s advanced availability for SCSK consulting /SI business and cloud services will become our weapon for the future.”

Secure Availability And Performance With SANLess Cluster Solution

Secure Availability And Performance With Sanless Cluster Solution

Secure High Availability And Performance In The Operating Environment Using Local Disk

MT Eye achieved a SANLess Cluster solution with SIOS DataKeeper and Windows Server Failover Clustering

MT Eye provides a variety of content services that are closely related to daily lives, including “music.jp” and “Lunarna”. Shared storage is critical to support their operation. However, each site had different storage requirements. And as shared storage provides one setting only, problems quickly surfaced.

The company switched to an operation system based on the local disk of each site. Under this new environment, the company aimed to secure the same availability as a cluster solution that does not require shared storage.

Switch From Shared Storage To Using Local disk For SANLess Cluster Solution

MT Eye mainly engages in content distribution services that makes everyday life happy and convenient. Their products range from entertainment to lifestyle information and health care.

Shared storage has been positioned as the center of IT infrastructure that supports the operation of various services. By allocating the volumes required by each site from the shared storage, the company enjoyed a cost-effective and efficient operation.

However, issues from the operation system gradually arose over the years. MT Eye was forced to make a big decision as their operational shared storage no longer had any maintenance service. Hiroyuki Okawa of foundation system division explained that there is no guarantee that their current IT system would run well even if they purchased a new shared storage. Also, they were running a risk where they might incur high cost to operate certain sites. Hence, Mt. Eye stepped up to operate a local disk for each site. Unfortunately, this also did not prove to be smooth sailing. Even if it is a local disk, it is necessary to maintain the same availability level as shared storage, and performance level must be upheld.

WSFC and DataKeeper Combined With Always On Ensures High Availability

In search for a solution, MT Eye first focused on using the Always On availability group, one of the functions of Microsoft SQL Server. It mirrored databases among multiple sites mutually and automatically failover in case of trouble. In order to use the Always On availability group, it is necessary to upgrade Microsoft SQL Server from Standard Edition to Enterprise Edition. To do this would result in a significant cost increase.

They found they could have a SANLess Cluster solution which used Windows Server standard failover clustering function and SIOS DataKeeper. Okawa emphasised that this way, they could continue to have Microsoft SQL Server as the Standard Edition. And yet at the same time, be assured of the same availability as the Always On availability group. It was also great to know that the cluster configuration that combines LifeKeeper and DataKeeper was already on another Linux system-based system.

Tomioka Tetsuhei of the Infrastructure Systems Department was still unsure. To ease his uncertainties, the company borrowed DataKeeper’s verification license from SIOS for testing. They assembled a cluster configuration close to the actual operation and repeated elaborate performance verification from February to March 2016. The performance deterioration was also seen when compared with the conventional system configuration using shared storage. He added that it was especially beneficial that they could pick between synchronous and asynchronous modes of replication depending on the system requirements.

Save On Data Center And Infrastructure Operation Cost

As of March 2017, MT Eye had already completed the transition to the SANLess Cluster solution for sites such as “Life Ranger Navi” (Life Information Service) and “Lunarna”. They were planning to finish the transition for the largest “music.jp” on the company’s website. With the completion, it was finally possible to provide storage resources corresponding to different requirements for each site such as performance emphasis and capacity emphasis.

If the company completely eliminated the use of shared storage, they could save on setting up a data centre. It also meant they could remove network equipment such as SAN switches from the rack together. In addition, the SANLess Clusters solution could also be migrated to major public cloud environments such as Amazon Web Service and Microsoft Azure. It could be said that the MT Eye infrastructure had acquired unprecedented agility and could respond to the demands of various sites.
