[. . . ] Similarly, z/VSE V4. 1 e -business Connectors are designed to support 2048-bit RSA keys in addition to 512-bit and 1024-bit RSA keys. In addition z/VSE now supports the IBM System Storage TS1120 encrypting tape drive which will encrypt data using the 256-bit AES algorithm. Management of keys is performed using IBM Encryption Key Manager (EKVM) which is a Java-based application running on z/OS, AIX, Linux, i5/OS, HP, Sun, and Windows systems. IBM-2007-04569-E-01 ©2007 Sine Nomine Associates 6 Impact: As the reliance on the Internet and network-enabled applications continues to increase it is important that any platform providing such applications can be confidently secured. The features of z9 and their exploitation by z/VSE provides this confidence. 3. 2. 6 SCSI Disk Support z/VSE 3. 1 introduced support of SCSI-based devices through an FBA-emulation layer that provides transparent access to these devices by existing, unmodified, applications. Facilities such as N_Port ID Virtualization (NPIV) allows secure access to SCSI end-points. z/VSE 4. 1 has introduced support of directly connected SCSI devices instead of mandating the presence of a switched fabric environment. Impact: z/VSE may now participate in a SAN environment which may improve the management of the storage environment of the site. Direct connection allows a site to "put their toe in the water" when it comes to SCSI without the expense of a complete switched fabric. 3. 3 Overall Technology Impact The impact of the technologies described in the previous sections is two-fold: 1. More effective integration with other mainframe and non-mainframe systems. Provides the building blocks which positions z/VSE to fully participate in enterprise-wide SOA strategies. IBM-2007-04569-E-01 ©2007 Sine Nomine Associates 7 4 Pricing and ROI In his "z/VSE 4. 1 Virtual Class" Klaus Goebel, the z/VSE Systems Manager, lists the five top concerns of z/VSE customers as: 1. Applications Historically, people have run z/VSE because it's lean and mean as well as having a portfolio of applications that facilitated doing business. Today's challenge is to maintain the platform's efficiency while integrating modern computing networks and applications. IBM has attempted to address these top concerns by a three pronged attack: 1. A "Protect, Integrate, and Extend" strategy to software and inter-operability. 4. 1 The Introduction of MWLC Pricing Midrange Workload License Charges (MWLC) is a monthly license charge price metric on the IBM System z9 Business Class (z9 BC) and the IBM System z9 Enterprise Class (z9 EC) servers that applies to z/VSE V4 and 12 key VSE middleware programs. The exception is for the z9-BC A01 which is subject to the zELC pricing mechanism. Similar to Workload License Charges and Entry Workload License Charges, you may implement MWLC in full-capacity or sub-capacity mode. Ø Full-Capacity: Programs are licensed and paid based on the IBM rated capacity of the z9 Server. Sub-Capacity: Programs are licensed and paid for based on the utilization of the Logical Partitions (LPARs) where the program executes. What counts as Full-Capacity? Ø 4. 1. 1 Full-Capacity pricing metric relies on the total rated capacity (measured in MSUs) of the machine where a product executes. IBM-2007-04569-E-01 ©2007 Sine Nomine Associates 8 4. 1. 2 What counts as Sub-Capacity? Sub-Capacity pricing metric relies on the utilization (based on peak 4-hour rolling average each month) of the LPAR(s) or guest Virtual Machines where a product executes. Note it is a peak of a rolling average, not the absolute peak of utilization. 4. 1. 3 Why MWLC? In his June 2006 article in the z/Systems Journal, Pete Clark gives the following example that illustrates why MWLC may be of benefit to sites running z/VSE: "In the past, the software pricing for every month would have been for full processor power. Now for 10 or 11 months of the year, software pricing will be at one-third full processor power, and for the one to two-month holiday rush actual utilization up to full power price. " The effect of MWLC is two-fold: it allows software to be paid for based on what is used rather than what capacity is available, and it provides a type of "capacity on demand" facility for those short periods when greater processing power is required. [. . . ] It is part of the TCP/IP for VSE product. Facilitates the printing of VSE/POWER list queue entries on any locally or LAN-attached printer. A tool to manage the VSE specific public key infrastructure. It can create RSA key pairs, create and sign certificates, and upload them to a VSE system. [. . . ]
