November 19, 2024	SIOS High Availability HA for Nutanix AHV Environments SIOS High Availability HA for Nutanix AHV Environments In today’s fast-paced IT environment, it’s crucial to keep your important data and applications available and reliable at all times. Nutanix AHV (Acropolis HyperVisor) stands out as a robust, enterprise-grade virtualization solution, offering seamless management and scalability. However, achieving high availability within Nutanix AHV environments requires a strategic approach, especially in Linux. SIOS offers comprehensive high availability and disaster recovery (HA/DR) solutions tailored specifically for Nutanix AHV environments running on Windows and all major Linux distributions, including Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Rocky Linux, and Oracle Linux. SIOS leverages clustering and automated failover technologies to provide unparalleled resilience to virtualized workloads running on Nutanix AHV. By integrating seamlessly with Nutanix AHV, SIOS extends its capabilities to offer automated monitoring, proactive detection of failures, and swift recovery mechanisms, ensuring minimal downtime and uninterrupted business operations. Application Aware High Availability What sets SIOS apart from other HA solutions is its unique application-aware HA capabilities. This means that not only is the infrastructure protected, but the applications themselves are monitored and protected against disruptions. SIOS ensures that critical workloads remain accessible and responsive through failures and outages, planned and unplanned. SIOS HA: Simple and Reliable Deployment and Management SIOS HA for Nutanix AHV environments simplifies deployment and management through its simple web management console and streamlined configuration processes. Administrators can easily set up HA clusters, define failover policies, and monitor the health of their virtualized infrastructure from a centralized dashboard. SIOS HA for Nutanix AHV environments combines the resilience of Nutanix AHV with the reliability of SIOS HA, offering organizations a robust solution to achieve continuous availability and mitigate the risks associated with downtime. Keep Essential Linux Applications Running without Downtime or Data Loss SIOS LifeKeeper for Linux is a simple, cost-efficient clustering software that provides complete high availability (HA) and disaster recovery (DR) protection for SAP, SAP S/4HANA, Oracle, MaxDB, and other essential applications operating in virtualized environments, as well as across physical, cloud, hybrid and multi-cloud. Applications protected by LifeKeeper keep running through a wide range of fault, failures, and local, site-wide, and regional disasters, enabling you to meet your availability SLAs with ease. Advanced Application Monitoring Unlike other clustering software that only monitors server operation, SIOS LifeKeeper monitors the health of the entire application environment. Fast, Reliable Failover When SIOS LifeKeeper detects an issue, it automatically restarts the application services on the same cluster node, often restoring operation. If necessary it fails over to the standby node(s), recovering application operation quickly and efficiently. Risk-Free Disaster Recovery Testing SIOS LifeKeeper’s switch over/switch back capabilities makes it easy to perform frequent, risk-free failover and DR testing to ensure the reliability of your application failover and DR. Wide-range Linux support SIOS LifeKeeper supports all major Linux distributions, including Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Rocky Linux, and Oracle Linux and accommodates a wide range of storage architectures. High Availability Protection for Windows Applications Protect critical Windows applications from downtime and disasters with SIOS DataKeeper Cluster Edition. Simply add SIOS DataKeeper to your Windows Server Failover Clustering (WSFC) environment for HA/DR clustering without the cost and single point-of-failure risk of shared storage. Fast, block-level replication synchronizes local storage on all nodes, giving the standby servers immediate access to your most current data in the event of a failover. Save Up to 70% on Software Licensing Costs Get enterprise-class clustering features without the need to upgrade to more expensive SQL Server Enterprise Edition or Oracle Database Enterprise Edition. Protect Unlimited Number of Databases Unlike SQL Server Always On Availability Groups, which has ~100 database limit, SIOS DataKeeper protects an unlimited number of databases. Complete Configuration Flexibility DataKeeper allows for multinode clusters without node limit, unlike SQL Server Always On Availability Groups. Easily add a DR node in the cloud or at a DR site, and mix physical, virtual, and cloud nodes. LifeKeeper for Windows is a tightly integrated combination of high availability (HA) failover clustering, continuous application monitoring, data replication, and configurable recovery policies. It delivers 99.99% application availability, and disaster recovery (DR) for applications running on Microsoft Windows Server in physical, virtual, cloud, hybrid cloud and multi-cloud environments. Application Intelligence SIOS LifeKeeper includes ARKs for critical applications like SQL Server, Oracle Database, Postgres SQL, and SAP HANA. These kits streamline setup, automate tasks, and manage failover according to best practices. Optimized for Performance SIOS LifeKeeper comes bundled with SIOS DataKeeper which provides block-level replication and integrated WAN acceleration for SANless clustering and DR. Achieve complete high availability (HA) and disaster recovery (DR) protection for critical Windows or Linux workloads in Nutanix AHV environments, as well as across physical, cloud, hybrid and multi-cloud.

November 1, 2024	Storage Considerations for Resizing Your Highly Available Cluster Storage Considerations for Resizing Your Highly Available Cluster When I was a Marine serving with a Tank Battalion, I remember that we’d all prepared ourselves to hear “FIRE IN THE HOLE” just before we shot a projectile. Even if you did not hear others yell this, we had radios/coms, hand/arm signals, flags, flares, etc. indicating that all things were “a go” and the projectile was headed down range. We all knew that communication was essential. The Importance of Communication in Cluster Storage Resizing If you are Database Administrator, Server Engineer or an IT generalist responsible for the health of the application resources on your cluster (DataKeeper storage), communication is essential for you too. For example, how do you notify others about your efforts to scale your storage? To be successful, it’s likely you are going to need to communicate with several other members of your team about a wide range of topics, related to your Source and Target Volumes, including: Do you need more space? Do you need to change your disk type from Basic to Dynamic? MBR (Master Boot Record) or GPT (GUID Partition Table)? Unit Allocation Size? Other Who on your team will yell “FIRE IN THE HOLE” when it’s time to provision your existing DataKeeper Mirror(s)? Don’t you want to be notified before and after? Key Steps for Coordinating DataKeeper Storage Resizing Your DataKeeper Storage requires a few things that need to be communicated to all stakeholders; internally or externally (hosted): Preparation: Have all the departments been notified of the said actions that will take place? Databases, Networking, Security, Applications, Client Services, etc. Have the steps been provided for resizing? Have those steps been shared with stakeholders that are impacted? Staging: Has the environment been “prepped” with the required resources? How much new storage is needed? Will the volume attributes remain the same i.e. Unit Allocation Size, MBR/GPT to name a few . . . Execution: Final walk through . . . All of the requirements have been gathered/reviewed again . . . via Preparation, Staging, etc Marine: “Are you ready?” Other Marines: “Yes!” (There is some swearing of course, WE ARE MARINES! LOL) Marine: “FIRE IN THE HOLE” DataKeeper Administrator: “Pause and Unlock Mirror” aka “FIRE IN THE HOLE” Greg Tucker, Sr. Product Support Engineer, SIOS Technology Corp.
