Upload ID

This is used by VSI internally. You don’t need it.

Max Alert Level

Of all the alerts on that system, here we show the level of the most serious.

Device Name

This is the name of the device as presented by the device itself

Display Name

The human-friendly description of the device

Collection Date

The date the data you are viewing was collected. VSI supports data collected at the daily and weekly levels

Upload Date

The date the data were uploaded

Days Old

The number of days since the data collection

Data Ctr

The Data Center where the device resides

Type

The type of device. For example, a NetApp array will appear as NETAPP_DEVICE.

Classification

Customers can define a “class of devices” and assign specific arrays to each customer defined class - such as “Block Flash” for Pure, Xtremio and IBM 9200 devices, or File Class for NetApp and Isilon arrays - this is a customer defined field

Raw

The raw amount of space supported by this device

Alloc

The total amount of allocated space on an array

Free

The total amount of free space on an array

Used

The total amount of (effective) used space on an array

Usable

The total amount of (effective) usable space. This is essentially the free space minus the overhead. Effective means data redcuton ratio is factored into this calculated value

% Used

The percentage of raw space currently in use.

Orphans

The amount of space on the array that is allocated but not attached to any host. It’s allocated but it can’t be used.

OrphanLuns

The number of LUNs that are not attached to a host.

Hosts

The total number of hosts attacked to this particular array

Pools

The total number of pools in use on the array

Savings

The dollar amount saved based on the deduplication statistics ??

# Drives

The total number of drives in the array

IOPS

The total number of IOPs during the collection period.

Latency

The latency, which measures how long users wait for disk activity, recorded during hte data collection

Type

not used at this time

Purchase Date

The date the array was purchased

End of Maint Date

The date your current maintenance contract ends on this device

End of Life Date

The date the array is to be removed from service

Contract Number

The maintenance contract number

Vendor

The vendor with whom you have the maintenance contract.

Tier

Displays the tier fo storage where this device

Category

The category for the device. This is specified by your IT department

Application

The primary application using the storage. For example, you might dedicate storage to a database or ERP solution.

Volume Locked Free

This is the amount of free space “inside volumes” on NetApp arrays where volume space guarantee is specified - this space is not usable for New volumes defined into aggregates on NetApp. (This is wasted space)

Model

The model number of the array

Firmware

The firmware version for the array

Count

Just set to 1 - used for counting items when filtering is used

Effective Free Space

Amount of Free space that is “usable” based on the number of places a standard volume can be provisioned on all your storage devices

Geography

Where the array is physically located

Physical Usable

Amount of physical usable space - does not include data reduction ratios

Physical Used

Amount of physical space used - no data reduction factor considered

Array Status

Array Status can be set by Customer - Active, Retiring, Decommissioned

Data Reduction Ratio

This is how much effective space can be stored from a “host perspective” on storage arrays based on overall data reduction ratio. This is calculated by - Effective Used / Physical Used

MB/SEC

megabytes per section metric in the current period for the devices - - 75% for the date being viewed

Growth

Is the array reporting Positive, Negative or no Growth (Arrow Up, Down or flat) - uses 6 month weighted average

Company

Company Name - used if multiple company names within 1 customer account
