Overview

The XtremIO Storage Array is an all-flash system, based on a scale-out architecture. The system uses building blocks, called X-Bricks, which can be clustered together. The system operation, controlled by a stand-alone dedicated Linux-based server, is called the XtremIO Management Server (XMS). Each XtremIO cluster requires an XMS host, which can be either a physical or a virtual server. A single XMS host can manage multiple clusters, so a single cluster may not require its own XMS host. The array continues operating if it is disconnected from the XMS, but cannot be configured or monitored.

XtremIO array architecture is designed to deliver the full performance potential of flash. Linear scaling of all resources, such as CPU, RAM, SSDs, and host ports, is done in a balanced manner. This allows the array to achieve any desired performance level, while maintaining consistency of performance that is critical to predictable application behavior. The XtremIO Storage Array provides a high level of performance that is consistent over time, system conditions, and access patterns. It is designed for high-granularity true random I/O.

Cluster performance level is not affected by capacity utilization level, number of volumes, or aging effects. Moreover, performance is not based on a "shared cache" architecture and is not affected by the data set size or data access pattern. Due to its content-aware storage architecture, XtremIO provides:

- Even distribution of data blocks, inherently leading to maximum performance and minimal flash wear

- Even distribution of metadata

- Freedom from hotspots in data or metadata

- Easy setup and no tuning

- Advanced storage functionality, including Inline Data Deduplication and Compression, thin provisioning, advanced data protection (XDP), snapshots, and more

- XtremIO Connector in UCS Director

XtremIO Connector in UCS Director

The XtremIO connector allows you to monitor and manage the XtremIO volumes, initiator groups, LUN mappings, snapshots, and basic network configurations. It connects through the HTTPS protocol. In order to manage XtremIO in Cisco UCS Director, the XMS Host IP is used when adding a physical account in Cisco UCS Director.

Consistency Groups

Consistency Groups (CG) are used to create a consistent image of a set of Volumes, usually used by a single application, such as a database. With XtremIO CGs, you can create a Snapshot of all Volumes in a group, using a single command. This ensures that all Volumes are created at the same time. Many operations that are applied on a single Volume can also be applied on a CG.

Snapshots

Snapshots are instantaneous copy images of Volume data. The state of the data captured is exactly as it appeared at the specific point in time that the Snapshot was created. This enables you to save the Volume data state and then access the specific Volume data whenever needed, including after the source Volume has changed.

A Snapshot can be taken either directly from a source Volume or from other Snapshots within a source Volume’s group (Volume Snapshot Group). XtremIO Snapshots are by default read-write, but can be created as read-only to maintain immutability.

The source data remains available without interruption, while the Snapshot can be used to perform other functions on the data. Changes made to the Snapshot’s source do not affect the Snapshot data.

XtremIO Snapshots are space-efficient both in terms of metadata consumed and physical capacity. Snapshots are implemented using redirect-on-write methodology. New writes to the source Volume (or Snapshot) are redirected to new locations, and only metadata is updated to point to the new data location. This method guarantees that there is no performance degradation while Snapshots are created.
