MURAL Software Standard Installation Guide

redundancy (transparent failover between pairs of active-active nodes).

UI/Caching (Rubix)—Hosts the Rubix engine and data cache. The Rubix

engine queries the Insta nodes constantly and when new data is available,

it fetches it to store in the data cache, so that it can respond more quickly

to requests from the UI engine. The Caching node is sometimes called the

Rubix node. The Caching node uses N+1 redundancy in active-active mode.

Compute node—Analyzes and aggregates the data, creating data cubes.

The Compute node cluster can have any number of servers, depending on

your deployment, and uses N+1 redundancy.

Insta node—Stores and manages the processed data in a columnar

database. It also manages the Insta database, which stores processed data

cubes. The Insta node cluster has two servers with 1+1 redundancy.

Apart from standard installations, MURAL system can be prepared with fewer

blades by accommodating two or three application components into a single

cluster, as described in the following sections.

Starter Pack Setup

In the Starter Pack setup, GMS, Collector (with Name-node) and UI components

are hosted together on the same cluster.

Medium Pack Setup

In the Medium Pack setup, GMS and Collector (with Name node) components are

hosted together on the same cluster.

Hardware

The MURAL application is hosted on the UCS 5108 Blade Server Chassis that

comprises GMS, Collector, Rubix, Compute and Insta nodes. Data storage is

hosted on the EMC storage devices.

The data flows that feed the MURAL system are pushed by an ASR 5000 or ASR

5500 platform (hereafter referred to as an ASR).
