FAQ: Can a customer with SVC Entry Edition (5639-VW2) convert to SVC standard (5639-VC5)?

Answer to this FAQ:

For customers who purchase SAN Volume Controller Entry Edition (5639-VW2), and who later need to increase their managed storage to greater than the maximum number of managed drives allowed by the 5639-VW2 license, IBM offers a conversion path to SVC 5639-VC5 (per terabyte charge unit) software. When converting a SAN Volume Controller Entry Edition 5639-VW2 cluster with licenses that may include Base Virtualization, FlashCopy, and Metro/Global Mirror, all the authorizations pertaining to that cluster must be converted to the appropriate 5639-VC5 (per terabyte) licenses. Conversion is a three stage process. First, the existing license for 5639-VW2 must be upgraded to the maximum supported drives (that is, 250 drives) for Base Virtualization, and also FlashCopy and Metro/Global Mirror if those functions are licensed. Next, the SVC license entitlement will be moved from SVC Entry Edition (5639-VW2) to a predetermined capacity amount in 5639-VC5 per TB pricing. For Base Virtualization, the entitlement is 71 TB; if licensed, for Metro/Global Mirror the entitlement is 14 TB. Entitlement for FlashCopy will not be moved to a predetermined capacity amount in 5639-VC5 except in cases where a monetary amount was paid for that SVC Entry Edition FlashCopy entitlement. As with the calculation used to determine the entitlements for Base Virtualization and Metro/Global Mirror that are provided, the FlashCopy entitlement will be calculated based on the actual amount paid for SVC Entry Edition FlashCopy and will not exceed the capacity of 13 TB. Finally, the new 5639-VC5 license may be upgraded further to meet the customer's requirements. For example, a customer has SVC Entry Edition (5639-VW2) licensed for 220 drives of Base Virtualization and Metro/Global Mirror. They want to expand their overall SVC capacity to 90 TB of Base Virtualization and 30 TB of Metro/Global. First, the customer would purchase quantity 30 of the SVC Entry Edition Base Virtualization per Disk Drive license and quantity 30 of the SVC Entry Edition Metro/Global Mirror per Disk Drive license to increase both to the maximum 250 drives, which is the conversion point. The conversion to SVC per terabyte licensing would entitle the customer to 71 TB of Base Virtualization capacity and 14 TB of Metro/Global Mirror capacity. Finally, the customer would purchase the additional 19 TB of SVC Base Virtualization capacity starting with terabyte number 72 in tier four and the additional 16 TB of SVC Metro/Global Mirror capacity starting at terabyte number 15 in tier two. There is no reverse path to convert from 5639-VC5 to 5639-VW2.
