SaltStack can be used to automate and orchestrate the provisioning of virtual machines on VMware ESXi 6.0. It implements the VMware APIs to allow defining VM profiles and templates that specify VM configurations, and then uses Salt commands to rapidly deploy new VMs from templates with customized configurations. Open-VM tools must be installed on templates to enable customizing VMs, such as setting the network configuration. Salt files define VM profiles and provider credentials, separating configuration from deployment logic for flexibility and reusability.

VSM (Virtual Storage Manager) is an open source tool developed by Intel to simplify Ceph storage cluster management. It includes a controller that runs on a dedicated server and manages Ceph through agents on each Ceph node. The VSM makes it easier to deploy, maintain, and monitor Ceph clusters, and also integrates with OpenStack for storage orchestration.

High Availability with MariaDB Enterprise by Stéphane Varoqui. Presented 26.6.2014 at the MariaDB Roadshow in Paris, France.

Galera Cluster for MySQL, Percona XtraDB Cluster and MariaDB Cluster (the three “flavours” of Galera Cluster) make use of the Galera WSREP libraries to handle synchronous replication.MySQL Cluster is the official clustering solution from Oracle, while Galera Cluster for MySQL is slowly but surely establishing itself as the de-facto clustering solution in the wider MySQL eco-system. In this webinar, we will look at all these alternatives and present an unbiased view on their strengths/weaknesses and the use cases that fit each alternative. This webinar will cover the following: MySQL Cluster architecture: strengths and limitations Galera Architecture: strengths and limitations Deployment scenarios Data migration Read and write workloads (Optimistic/pessimistic locking) WAN/Geographical replication Schema changes Management and monitoring

This document provides an overview of advanced SQL Server techniques and best practices when running SQL Server in a virtualized environment on vSphere. It covers topics such as storage configuration including VMFS, block alignment, and I/O profiling. Networking techniques like jumbo frames and guest tuning are discussed. The document also reviews memory management and optimization, CPU sizing considerations, workload consolidation strategies, and high availability options for SQL Server on vSphere.

We will show how Galera Cluster executes DDLs in a safe, consistent manner across all the nodes in the cluster, and the differences with stand-alone MySQL. We will discuss how to prepare for and successfully carry out a schema upgrade and the considerations that need to be taken into account during the process.

Running Galera Cluster in Microsoft Azure involves setting up virtual machines and installing Galera Cluster software. This provides more control than Azure Database for MySQL, which uses asynchronous replication. While Azure Database for MySQL is fully managed, Galera Cluster in VMs supports the virtually synchronous replication that is its core feature. Cost estimates show running three Galera Cluster nodes in VMs costs less monthly than three hosted MySQL instances in Azure Database for MySQL.

Want to understand how to set high availability solutions for MySQL using MariaDB Galera Cluster? Join this webinar, and learn from experts. During this webinar, you will also get guidance on how to implement MariaDB Galera Cluster.

This document summarizes the performance of an all-NVMe Ceph cluster using Intel P3700 NVMe SSDs. Key results include achieving over 1.35 million 4K random read IOPS and 171K 4K random write IOPS with sub-millisecond latency. Partitioning the NVMe drives into multiple OSDs improved performance and CPU utilization compared to a single OSD per drive. The cluster also demonstrated over 5GB/s of sequential bandwidth.

This set of slides gives you an overview of Galera, configuration basics and deployment best practices. The following topics are covered: - Concepts - Node provisioning - Network partitioning - Configuration example - Benchmarks - Deployment best practices - Galera monitoring and management

This document compares various MySQL replication options including asynchronous replication, semi-synchronous replication, Schooner Active Cluster synchronous replication, Oracle GoldenGate, Tungsten Replicator, and Linux DRBD. It finds that asynchronous and semi-synchronous replication in MySQL 5.5.8 have limited sustainable performance and can result in premature sharding, while Schooner Active Cluster provides a 4-5x boost in sustainable replication performance through its tightly-integrated synchronous approach. The document also includes results from the DBT2 benchmark showing differences in throughput, response time, CPU and storage utilization, and network bandwidth across the different solutions.

There’s lots of new stuff in this release, including better high availability for Hyper-V, greater control over resource utilization, improved fault tolerance of transient events, newer design options for stretch or multi-site clusters, a whole new way of doing software defined storage with SATA and NVMe drives, built-in block-level storage replication, and hyper-convergence without having to break the bank.

We continuously see great interest in MySQL load balancing and HAProxy, so we thought it was about time we organised a live webinar on the topic! Here is the replay of that webinar! As most of you will know, database clusters and load balancing go hand in hand. Once your data is distributed and replicated across multiple database nodes, a load balancing mechanism helps distribute database requests, and gives applications a single database endpoint to connect to. Instance failures or maintenance operations like node additions/removals, reconfigurations or version upgrades can be masked behind a load balancer. This provides an efficient way of isolating changes in the database layer from the rest of the infrastructure. In this webinar, we cover the concepts around the popular open-source HAProxy load balancer, and show you how to use it with your SQL-based database clusters. We also discuss HA strategies for HAProxy with Keepalived and Virtual IP. Agenda: * What is HAProxy? * SQL Load balancing for MySQL * Failure detection using MySQL health checks * High Availability with Keepalived and Virtual IP * Use cases: MySQL Cluster, Galera Cluster and MySQL Replication * Alternative methods: Database drivers with inbuilt cluster support, MySQL proxy, MaxScale, ProxySQL

This document discusses redundancy models for MySQL, MariaDB, MongoDB and TokuMX databases. It covers asynchronous replication used in MySQL replication and MongoDB/TokuMX compared to synchronous replication in Galera and NDB Cluster. The document then zooms into recovery procedures for Galera clusters and discusses how to prevent split-brain situations in multi-datacenter setups through the use of additional nodes and assigning node weights.

You'll learn how Galera integrates with MySQL 5.6 and Global Transaction IDs to enable cross-datacenter and cloud replication over high latency networks. The benefits are clear; a globally distributed MySQL setup across regions to deliver Severalnines availability and real-time responsiveness. Galera Cluster for MySQL is a true multi-master MySQL replication plugin, and has been proven in mission-critical infrastructures of companies like Ping Identity, AVG Technologies, KPN and HP Cloud DNS. In this webcast you¹ll learn about the following Galera Cluster capabilities, including the latest innovations in the new 3.0 release: Galera Cluster features and benefits Support for MySQL 5.6 Integration with MySQL Global Transaction Identifiers Mixing Galera synchronous replication and asynchronous MySQL replication Deploying in WAN and Cloud environments Handling high-latency networks Management of Galera

This document discusses online migration from an existing MySQL master-slave setup to a Galera cluster. It outlines the steps to enable binary logging on the slave, dump the schema and data, load this into the first Galera node to initialize replication, and transition reads to the Galera cluster while writes continue on the master initially at 90% before being cut over fully to the cluster. Operational checklists, backup procedures, and disaster recovery options for the new Galera cluster configuration are also reviewed.

This document discusses considerations for migrating to Galera Cluster replication from MySQL or other database systems. It covers differences in supported features between Galera and MySQL, including storage engines, tables without primary keys, auto-increment handling, and DDL processing. It also addresses multi-master conflicts, long transactions, LOAD DATA processing, and using Galera with MySQL replication. An overview of online migration is provided along with guidance on validating schemas and checking for compatibility prior to migration.

Database schema changes are usually not popular among DBAs or sysadmins, not when you are operating a cluster and cannot afford to switch off the service during a maintenance window. There are different ways to perform schema changes, some procedures being more complicated than others. Galera Cluster is great at making your MySQL database highly available, but are you concerned about schema changes? Is an ALTER TABLE statement something that requires a lot of advance scheduling? What is the impact on your database uptime? This is a common question, since ALTER operations in MySQL usually cause the table to be locked and rebuilt – which can potentially be disruptive to your live applications. Fortunately, Galera Cluster has mechanisms to replicate DDL across its nodes. In these slides, you will learn about the following: How to perform Zero Downtime Schema Changes 2 main methods: TOI and RSU Total Order Isolation: predictability and consistency Rolling Schema Upgrades pt-online-schema-change Schema synchronization with re-joining nodes Recommended procedures Common pitfalls/user errors The slides are courtesy of Seppo Jaakola, CEO, Codership - creators of Galera Cluster

Slides for the webinar held on January 21st 2014 Repair & Recovery for your MySQL, MariaDB & MongoDB / TokuMX Clusters Galera Cluster, NDB Cluster, VIP with HAProxy and Keepalived, MongoDB Sharded Cluster, etc. all have their own availability models. We are aware of these availability models and will demonstrate in this webinar how to take corrective action in case of failures via our cluster management tool, ClusterControl. In this webinar, Severalnines CTO Johan Andersson will show you how to leverage ClusterControl to detect failures in your database cluster and automatically repair them to maximize the availability of your database services.
