High Availability Clusters for Physical Servers

SIOS cluster software provides the enterprise-grade high availability, reliability, and flexibility needed for your most important applications when operating in physical server environments. Use SIOS Protection Suite for Linux to protect critical Linux applications like SAP and databases such as Oracle, MySQL, or Postgres. SIOS DataKeeper provides a unique software add-on to Microsoft Windows Server Failover Clusters (WSFC) to allow Microsoft Clusters and SQL Server workloads to run on physical servers without a SAN.

SIOS software lets you use your choice of industry-standard hardware to create high availability clusters. You can use shared storage in a SAN environment or simple, low-cost local storage. Use SIOS software to add DR protection to an existing cluster or to provide complete failover protection in Windows or Linux environments where shared storage clusters are impossible or impractical, such as cloud, virtual servers, and high-performance storage environments.

Easy to use. Easy to own. The intuitive SIOS interface lets you configure and begin using a SANless cluster in minutes. SIOS also makes monitoring and management of your clusters easy with a user-friendly management console that lets you monitor the status of protected servers, communication paths, resources, and applications.

Application and Data Protection for Server using Real-Time Replication

SIOS clusters allow high availability configurations using a local LAN and high speed synchronous block-level replication.

SIOS software uses real-time replication to synchronize storage on the primary server with storage on a standby server located in the same data center, in your disaster recovery site, or both. This allows you to build high availability and disaster recovery configurations flexibly; Two node or multi-node.

SIOS block level replication is highly optimized for performance. You can even use super fast, high-speed locally attached storage such as PCIe flash type storage devices on your physical servers to achieve very low cost, high performance, high availability configurations. Your data is protected on the flash device and your application too.

You can mix and match SAN-based clusters with SIOS SANless clusters. Just add SIOS SANless cluster software to a SAN-based cluster and put the third node into a remote data center or the cloud and achieve full disaster recovery protection. In the event of a disaster, the standby remote physical server is brought into service automatically with no data loss, eliminating the hours needed for restoration from backup media.

Service Level Agreements and the Four Nines are Not Enough for High Availability in the Cloud

July 15, 2023 by Jason Aw Leave a Comment

Service Level Agreements and the Four Nines are Not Enough for High Availability in the Cloud

When most people think of high availability, they set four nines (99.99%) or less than five minutes of downtime every month as the baseline. But according to Dave Bermingham, Senior Technical Evangelist at SIOS Technology, in this TFiR video interview, high availability is more than that.

Dave argues that counting on nines is really a measurement that you might be judged against, but really trying to guarantee a level of nines is almost impossible. Because there’s so many points in that availability chain that can be a single point of failure. Four nines is certainly a great number to be judged against and to strive for, but overall it doesn’t mean a lot to have just four nines for my database server.

Effective High Availability Covers a Complex Availability Chain

Even with Cloud SLAs (Service Level Agreements), one can’t be fully rest assured as most cloud providers offer four nines on compute, which is only one part of the availability chain (along with network, storage, and the hops between). Bermingham warns, “There’s a million points of failure. So, trying to think that my cloud provider offers four nines so I’m covered, you’re kind of fooling yourself there. You have to look at the big picture and do what you can to identify those points of failures, to minimize the potential points of failure and to have a recovery plan, should something happen.”

When considering High Availability/Disaster Recovery (HA/DR), Bermingham believes the thing that causes the most visible downtime is human error. Bermingham also suggests that authorization and access to the system should also be restricted to reduce the point of failure. “You should only give access to those who absolutely need access to it and you should also ensure that they are highly trained and that you have all the things in place to help minimize potential oops.”

SIOS offers a single solution to meet both high availability and disaster recovery needs across a wide variety of operating systems (Windows, Linux), platforms, and applications, including SAP, SAP HANA, MaxDB, SQL Server, Oracle, and other environments running in SAN-based, shared storage configurations or SANless, local data storage configurations.

Protect transactional, processing and administrative financial systems in Windows or Linux environments
Monitor and protect application operation and availability
Move critical systems to the cloud without sacrificing HA or configuration flexibility
Minimize the need for failover with automatic restart functionality
Reliable failover with application-specific intelligence

HA in the Cloud

Cloud infrastructure does not automatically provide application-level HA or disaster recovery protection. Cloud availability service-level agreements apply only to the hardware, which may not ensure that an application or database remains accessible.

SIOS HA clustering for applications in the cloud fails over across both cloud regions and availability zones. Traditional shared storage clustering in the cloud is costly and complex to configure, and is sometimes not available. SIOS DataKeeper Cluster Edition provides block-level replication to synchronize local storage among each cluster node. This enables a standby node to access an identical copy of the primary node storage and an RPO of zero.

Meet Stringent Availability SLAs

SIOS clustering software monitors application availability and if a threat is detected, this software moves the application operations to a standby server where operation continues with minimal downtime and near zero data loss.

Disaster Recovery

Some applications need protection from disasters that damage the local IT infrastructure on premises or in the cloud. SIOS clustering software enables failover across geographically separated cluster nodes and across cloud regions and availability zones for complete DR protection.
