The following diagram shows the components of a cluster: Figure 1. Cluster components A cluster provides the following benefits: ● Reduced management complexity. ● Enhanced performance and resource efficiency. Compute and storage resources are pooled within a cluster and the resources usage is balanced across all of the cluster's appliances. Resources are re-balanced as needed to maintain and optimize the cluster's performance and resource usage. This is done based on the storage space usage trends and system performance evaluations occurring in the backend. ● Scalability. Start with a small configuration and easily add capacity or performance to the system by adding more appliances later to meet business demand. To manage and configure a cluster, perform the following operations in the PowerStore Manager ● Monitor and review aggregated metrics for the cluster on the Dashboard page. ● Review and configure various settings for your cluster on the Settings page. ● Add appliances to or remove them from the cluster Hardware page. Planning and installation overview This section provides a high-level map of the steps you should plan on taking from planning through installation, and finally logging on to the PowerStore Manager user interface. Ensure that you see the associated documentation resources for detailed instructions and recommendations. You can access the documentation resources on the PowerStore Documentation page at https://www.dell.com/powerstoredocs. Before the appliance arrives: 1. Work with your infrastructure administrators to: a. Configure your network and Top-of-Rack (TOR) switches based on the recommendations that are provided in the PowerStore Networking Guide for PowerStore T Models or PowerStore Networking Guide for PowerStore X Models. b. Obtain network-related information that you require for initial configuration of your cluster. Use the PowerStore Networking Guide for PowerStore T Models or PowerStore Networking Guide for PowerStore X Models to plan and collect this information. c. Configure the network ports to allow the cluster to communicate with pertinent hosts and applications securely and efficiently. See Port usage on page 25 for more information. 2. PowerStore requires a data center or server room that is equipped with controlled electrical, environmental, cabling, and safety systems. Plan the site where you will install the appliances and the location of the appliance components (base enclosures and expansion enclosures) in a rack. See Site Planning on page 9 for more information. 3. Set up a workstation that you will use to discover the appliances and configure the cluster. You may also need to download a Discovery Utility from the support website and install it on this workstation. See Workstation requirements on page 17 for more information. 4. Determine the drive failure tolerance level you want to set on each appliance. The drive failure tolerance level indicates the amount of concurrent drive failures the appliance can sustain without causing a data unavailable or data loss event. The single drive fault tolerance level meets availability requirements for all drive types and capacity points, but the double drive failure tolerance can provide higher resiliency and protection. You cannot change the drive fault tolerance level after you have set it. Ensure that the enclosure includes the following number of SSD drives: ● At least six drives for single drive failure tolerance ● Seven drives for double drive failure tolerance Introduction 7

A cluster provides the following benefits:
●
Reduced management complexity.
●
Enhanced performance and resource efficiency. Compute and storage resources are pooled within a cluster and the
resources usage is balanced across all of the cluster's appliances. Resources are re-balanced as needed to maintain and
optimize the cluster's performance and resource usage. This is done based on the storage space usage trends and system
performance evaluations occurring in the backend.
●
Scalability. Start with a small configuration and easily add capacity or performance to the system by adding more appliances
later to meet business demand.
To manage and configure a cluster, perform the following operations in the PowerStore Manager
●
Monitor and review aggregated metrics for the cluster on the
Dashboard
page.
●
Review and configure various settings for your cluster on the
Settings
page.
●
Add appliances to or remove them from the cluster

page.

Before the appliance arrives:
1.
Work with your infrastructure administrators to:
a.
Configure your network and Top-of-Rack (TOR) switches based on the recommendations that are provided in the
PowerStore Networking Guide for PowerStore T Models or PowerStore Networking Guide for PowerStore X Models
.
b.
Obtain network-related information that you require for initial configuration of your cluster. Use the
PowerStore
Networking Guide for PowerStore T Models or PowerStore Networking Guide for PowerStore X Models
to plan and
collect this information.
c.
Configure the network ports to allow the cluster to communicate with pertinent hosts and applications securely and
efficiently. See
