Introduction

The File IQ Sizing Tool is a spreadsheet that produces recommendations about the most appropriate instance type to use based on inputs you provide.

Considerations

When sizing your File IQ setup, a few core inputs must be considered before selecting an appliance type and instance. Entering these specifications into the Sizing Tool provides you with the minimum hardware requirements.

These input considerations include the following:

• Number of Volumes (with estimated number of files)

• Volume Change Rate (estimated monthly)

• Number of NEAs (sized by number of active users)

Using these inputs, the Sizing Tool provides the following minimum virtual machine requirements:

• Instance Type (vCPUs, Memory)

• Cache Disk Size

• CoW Disk Size

• File IQ Database Size

Note: File IQ does not support disk striping on cache or DB disks.

Sizing Tool

The Sizing Tool includes the Volumes, NEAs, and Minimum Hardware Requirements tables. Values are entered into the Volumes and NEAs tables, and your minimum requirements are displayed in the Minimum VM Hardware Requirements table and Minimum Disk Requirements table.

Note: Only enter table values in the light blue cells. Each table description specifies the specific table columns and rows that are light blue.

Note: Table values entered that are outside the confirmed operational capabilities are highlighted in yellow and red cells. The color definitions are as follows:

Grey/green cells: Within operational capability. The system has been verified to work within this operational range.

Yellow cell: Yet to be confirmed operational ranges. The system has yet to be verified to work with these operational values.

Red cell: Beyond the operational capabilities of the system. Adjust the sizing tool input figures to bring the operational range back within operational capability.

Volumes Table

In the Volumes table, follow these steps:

1. For Small volumes (around 1,000,000 or fewer files and directories), enter your estimate of how many such volumes are expected to change by < 5 percent, < 10 percent, < 20 percent, and > 20 percent.

2. For Medium volumes (around 10,000,000 or fewer files and directories), enter your estimate of how many such volumes are expected to change by < 5 percent, < 10 percent, < 20 percent, and > 20 percent.

3. For Large volumes (around 50,000,000 or fewer files and directories), enter your estimate of how many such volumes are expected to change by < 5 percent, < 10 percent, < 20 percent, and > 20 percent.

4. For volumes with greater than 50,000,000 files and directories, enter the estimated size of the volume in the “Files + Dir / Volume” column, then enter your estimate of how many such volumes are expected to change by < 5 percent, < 10 percent, < 20 percent, and > 20 percent.

5. This table then automatically calculates the following results:

• Total estimated number of files and directories.

• Total number of volumes that are expected to change by < 5 percent, < 10 percent, < 20 percent, and > 20 percent.

• Total number of volumes.

Tip: Use the Summary page on the Nasuni Orchestration Center (NOC) Dashboard to help identify the total number of files across all volumes (Total Files). Since this value includes all data written, overwritten, and deleted from the cloud, you should reduce it slightly.

The following example demonstrates 2 “Large” volumes that each contain 50,000,000 files, collectively adding up to 100 million files with a <5% file change rate.

Note: Check for yellow and red cells in the table, as they highlight values entered that have yet to be confirmed as supported or are outside operational capabilities.

NEAs (Nasuni Edge Appliance) Table

The NEAs table provides an estimate of the number of events per second (abbreviated as “Ev/s”) per Edge Appliance.

In the NEAs table, follow these steps:

1. For Extra Small (< 50 users), enter how many such NEAs you have.

2. For Small (50-100 users), enter how many such NEAs you have.

3. For Medium (100-250 users), enter how many such NEAs you have.

4. For Large (250-500 users), enter how many such NEAs you have.

5. For Extra Large (500-1000 users), enter how many such NEAs you have.

6. For NEAs with greater than 1000 users, enter how many such NEAs you have.
   Then, in the Est Ev/s/NEA column, estimate how many events per second such an NEA generates.

7. This table then automatically calculates the following results:

• Total number of NEAs.

• Total estimated events per second.

In this example, there are 5 Edge Appliances with between 100 and 250 active users per Edge Appliance. Entering “5” in the NEA Count column for Medium (100-250) results in a total of 5 NEAs and a total of 250 events per second.

Tip: If you are unsure of the NEA size, start by sizing one or two of your NEAs and using the Event Dashboard to provide a better estimate.

Note: Check for yellow and red cells in the table, as they highlight values entered that are yet to be confirmed supported or outside operational capabilities.

Minimum VM Hardware Requirements Table

As you enter values into the Volumes and NEAs tables, the Minimum VM Hardware Requirements table updates to reflect the minimum number of vCPUs and the minimum amount of memory necessary for the File IQ Appliance virtual machine. Finally, a recommended instance size is provided.

Using the above example inputs from the Volumes and NEAs tables, the Minimum VM Hardware Requirements table provides recommendations for the following hardware requirements and instance type.

Note: The FIQ DB Disk Size cell turns red if the disk size is outside operational capabilities.
