Starwind Software Enterprise CDP Edition with 2 Product Details
StarWind Enterprise Server license is required for the server designated as the primary storage controller and includes unlimited concurrent iSCSI client connections, support CDP/snapshot features and a limit of 4TB of storage capacity. One Enterprise Server license permits installation only on one storage node. Please note that this license does not allow the use of two storage servers and requires an upgrade to StarWind Enterprise Mirroring & Replication for configuring data mirroring or remote replication from the primary to the secondary node.
^^ CDP & Snapshots: captures point-in-time snapshots with unlimited rollback points
^^ Server Clustering: provides shared storage for High Availability server clustering
^^ Thin Provisioning: allocates space dynamically for highly efficient disk utilization
CDP and Live, Point-in-Time Snapshots
StarWind’s Snapshots capture a volume’s state at any point in time. You can perform the Snapshots manually or have them scheduled. These live, point-in-time Snapshots are instant and capture a consistent state of the data you have stored on the SAN.
Point in Time Snapshots
• Instantly recover and roll back an entire disk volume or individual files and folders
• Perform manually or schedule and capture point-in-time block level copies
StarWind Enterprise Server helps you create and provide shared storage for your server clusters, which is used to increase reliability and availability of your application and data. A cluster is a group of independent servers working together as a single system to ensure that mission-critical applications and resources are as highly-available as possible. The group of computers is managed as a single system, shares a common namespace, and is specifically designed to tolerate component failures. A cluster supports the addition or removal of components in a way that’s transparent to users. The general concept in clustering is that there are nodes, which are computers that are members of the cluster that are either active or passive. Active nodes are running an application or service while passive nodes are in a standby state communicating with the active nodes so they can identify when there is a failure. In the event of a failure, the passive node then becomes active and starts running the service or application.
Clustering, at the most basic, is combining two servers so that a failure will not result in a long outage and lost availability. In the case of a cluster, the redundancy is at the server computer level, however, the redundancy is configured per service or application. The following figure shows two nodes that connect to a shared storage device or a SAN that is provided using StarWind Enterprise Server.
Thin Provisioning, combined with the ability to scale storage clusters dynamically, allows you to purchase only the storage you need today, and add more storage to the cluster as application data grows. This allows you to raise storage utilization levels, increase return on investment, and make the constantly falling price of storage per gigabyte work to your advantage. You can purchase storage as needed without over-provisioning storage. Thin Provisioning is implemented consistently and it's the mechanism that makes Automatic Snapshots, Remote Replication and Synchronous Data Mirroring all space efficient.
StarWind Thin Provisioning helps you to use storage more efficiently and allocate only the space that you actually use:
^^ Purchase storage as you need it, not in advance
^^ ^^ Do more with less storage, increasing flexibility
Raise utilization, efficiency, and ROI
^^ Take advantage of constantly falling prices per gigabyte
^^ Reduce energy consumption and carbon footprint
