[. . . ] z/VSE now supports the CP Assist for Cryptographic Functions (CPACF) for using Advanced Encryption Standard (AES) for 128-bit keys. TCP/IP is designed to use 512-bit and 1024-bit RSA keys transparently. TCP/IP will support 2048-bit RSA key with a Crypto Express2 adapter in either coprocessor or accelerator mode. 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. [. . . ] The tool reads WSDL files and Copybooks and creates proxy code that you use as a layer between existing programs and the VSE SOAP engine Redirects all accesses to a certain VSAM file into any other file system or database on any other (Java-enabled) platform. Provides access to VSE resources using the Java based connectors, but without writing Java programs. The tool can create a map from parsing a COBOL or PL/I copy book Provides a graphical user interface (GUI) for the VSE operating system, which behaves very much like file managers from other platforms, such as Windows Explorer. It includes host based VSE file systems (VSE Librarian, POWER queues, ICCF, VSAM) and provides host specific functions. [. . . ]
