Flash Alert : TS7700 Potential Performance Issue with R3.0 code and 3957 VEA/V06 models

For those who are in this situation, you might have a look at this before upgrading to the R3.0 (8.30.x.x) release level. I'm taking over the info from the alert you can also find over here.

Abstract

TS7700 8.30.x.x levels may cause a performance degradation when installed on the TS7720 (3957-VEA) or the TS7740 (3957-V06) hardware model base.

Content

MachineType/Model affected: TS7720 (3957-VEA), TS7740 (3957-V06).

It has been determined by IBM that TS7700 3.0 Release levels (8.30.x.x) may cause a performance degradation when installed on the TS7720 (3957-VEA) and the TS7740 (3957-V06) hardware model base. Customers considering an upgrade to the R3.0 (8.30.x.x) release level on these models, or installing a TS7720 expansion frame, 3952-F05 w/ FC 7332, are strongly advised to have a SCORE request submitted, allowing IBM to assess current performance requirements and to provide a recommended upgrade path. Environments that run performance-sensitive, or high-throughput workloads on VEA or V06 hardware platforms will require special consideration. Customers should contact their IBM sales team for assistance submitting the SCORE request so that the appropriate technical reviews can be completed.

This does not apply to customers with TS7720 (3957-VEB) and/or TS7740 (3957-V07), who may upgrade to R3.0 without restriction.
