The percentage of total workload storage operations that are “reads” (as opposed to “writes”).
The number of baseline drives.
The amount of storage capacity on each drive.
The percentage of physical storage capacity that is allocated to the SSD controller. This impacts drive performance.
The type of RAID configuration being used impacts performance and usable capacity required for the storage environment. It also impacts the minimum number of drives needed.
SSD and Hard Drive prices are calculated based on user input for drive type and capacity. Hard Drive price may not reflect the latest price in the market. Solidigm assumes an Average Selling Price for Hard Drives based on OEM pricing. Solidigm SSD pricing is based on recommended customer price. This value can be modified to reflect a more appropriate drive cost.
The physical size of each drive.
The type of connection for this SSD.
The number of drives that can fit into a single enclosure. This determines how many enclosures are needed, which affects cost.
Interface used by the drive to communicate with the host system. This affects the default cost and performance of the drive.
The estimated probability that a drive will fail during a full year of use.
Read speed for a single drive. This input is only available when Workload is set to Sequential.
Write speed for a single drive. This input is only available when Workload is set to Sequential.
Rate of power consumption when a drive is not in use.
Rate of power consumption when a drive is fully utilized.
The data reduction ratio (DRR) achieved through methods like compression/deduplication. A higher ratio means the data on the drive is more compressible and takes up a smaller part of the drive’s usable capacity.
Automatically calculate Number of New Drives for Options 1, 2, and 3 by matching the capacity, performance, or TCO of the baseline configuration.
Changes currency throughout the Estimator. Currency exchange rates are updated daily.
The number of years that drives are used before being replaced by new drives.
Amount you pay per kilowatt hour of electricity.
The amount of power (in watts) consumed by an enclosure at full utilization (not including the power consumed by the drives within the enclosure).
Average IT labor cost for a single drive failure.
Number of watts of electricity required to cool one watt of heat.
The percentage of the total capability of the drive that is being used (example: at 50% duty cycle the drive is being used at half of the max rated performance). Alternately, it could mean the percentage of time per day that the drive is being used at max performance.
