Ibm Storage Utility Offerings - IBM Storwize V5010 Manual

1.3.1 IBM Storage Utility Offerings

The IBM 2078 Model U5A is the IBM Storwize V5030 with a three-year warranty, to be utilized
in the Storage Utility Offering space. These models are physically and functionally identical to
the Storwize V5030 model 324 with the exception of target configurations and variable
capacity billing. The variable capacity billing uses IBM Spectrum Control™ Storage Insights
to monitor the system usage, allowing allocated storage usage above a base subscription
rate to be billed per TB, per month.

other hosts), whether data is written or not. For thin-provisioning, the data that is actually
written is considered

IBM Storage Utility Offerings include the IBM FlashSystem® 900 (9843-UF3), IBM Storwize
V5030 (2078-U5A), and Storwize V7000 (2076-U7A) storage utility models that enable
variable capacity usage and billing.
These models provide a fixed total capacity, with a base and variable usage subscription of
that total capacity. IBM Spectrum Control Storage Insights is used to monitor the system
capacity usage. It is used to report on capacity used beyond the base subscription capacity,
referred to as variable usage. The variable capacity usage is billed on a quarterly basis. This
enables customers to grow or shrink their usage, and only pay configured capacity.
IBM Storage Utility Offering models are provided for customers who can benefit from a
variable capacity system, where billing is based on actually provisioned space above the
base. The base subscription is covered by a three-year lease that entitles the customer to
utilize the base capacity at no additional cost. If storage needs increase beyond the base
capacity, usage is billed based on the average daily provisioned capacity per terabyte, per
month, on a quarterly basis.
Example
A customer has a Storwize V5030 utility model with 2 TB nearline disks, for a total system
capacity of 48 TB. The base subscription for such a system is 16.8 TB. During the months
where the average daily usage is below 16.8 TB, there is no additional billing.
The system monitors daily provisioned capacity and averages those daily usage rates over
the month term. The result is the average daily usage for the month.
If a customer uses 25 TB, 42.6 TB, and 22.2 TB in three consecutive months, Storage
Insights calculates the overage as follows (rounding to the nearest terabyte) as shown in
Table 1-7.

The capacity billed at the end of the quarter will be a total of 39 TB-months in this example.
Disk expansions (2076-24F for the Storwize V7000 and 2078-24F for the Storwize V5030)
may be ordered with the system at the initial purchase, but may not be added through MES.
The expansions must have like-type and capacity drives, and must be fully populated.
