IT Management

With his plan in place, Jim was ready to bring his STASH project to management’s attention. His manager in Washington immediately saw the immense value that Jim’s project could deliver and approved his integration work.

With developmental efforts under way, Jim turned his attention to sales and distribution. He made IBM marketing aware of what he was doing, but chose to use a trusted IBM distribution partner (Vicom Infinity) to help package and sell this trusted thin client mainframe solution. Vicom Infinity’s approach is to combine proven technology with innovative thinking. The results are powerful systems, based on IBM System zEnterprise servers that fully integrate with strategic business applications.

Impact for IBM and Customers

What Jim, a select group of compatriots at IBM, and the STASH project members are creating is a highly secure, trusted thin client mainframe environment. This kind of environment could be highly useful in secure government environments as well as in banking and finance, healthcare, retail, and most businesses that have thin client needs.

Especially noteworthy about the STASH design is that it capitalizes on IBM’s System z virtualization, security and reliability features, including global mirroring. The goal is to provide a desktop hosting environment on the recently introduced System z BladeCenter Extension (zBX) that leverages mainframe management capabilities and reduces the number of servers and cost to deploy trusted thin clients. Ultimately, through use of the z86VM product from Mantissa, a complete reduction in servers necessary to host PCs may be possible. Perhaps 50,000 desktops could be supported across four mainframes instead of 500 virtualized x86 servers. You’ll have to wait until the second half of 2012 to see if that becomes possible.

This design enables clients who use the CSL guest management software to do their normal business activities by day, then tap the unused mainframe computing power at night to perform other functions such as executing analytics queries. This could reduce an entire tier of servers that might otherwise have been deployed. That’s not possible with today’s x86-based virtualization solutions.

For IT buyers who use traditional x86-based thin client solutions, using the STASH mainframe approach greatly simplifies management and reduces costs, especially for labor. Centralized management with advanced management tools makes it possible:

  • For fewer managers to manage larger populations of users
  • To more easily conduct software distribution and patch management activities.

By using RTCS Trusted Thin Client (TTC) software, along with standard “off the shelf” thin client hardware, users benefit from a secure operating environment that mitigates advanced persistent threats and inhibits data leakage. TTC also provides for network segmentation or separation. Users have access only to data on authorized networks and can’t cut and paste from one network to another. Traditionally, this required use of multiple desktop machines, but TTC eliminates that need. Users can access multiple networks, securely, from a single desktop device. TTC greatly reduces administration by not requiring administrators to patch and maintain embedded thin client device software such as Windows CE. There’s also a reduction in power use since thin clients use more than 70 percent less power than PCs.

For clients that must have a highly available environment, this STASH architectural design essentially makes it possible to provide fault-tolerant desktops (because a failed virtual desktop can automatically failover to another virtual desktop image) and the “traditional” mainframe resilience can provide global mirroring of desktop resources. Enterprises seeking a resilient desktop environment should be particularly interested in this feature.

Finally, this environment should burn far less electricity than a PC server environment because a mainframe can perform the work of hundreds of servers and desktops using only 20 percent or less the amount of energy.

There’s a hidden jewel, too. Project STASH can help bring IT organizations back together. Instead of compartmentalized organizations that manage PCs independently from x86 servers, UNIX servers and mainframes, use of the STASH approach fosters greater IT collaboration to reduce costs and risks, improve security and resilience, and protect investments for the future. Application developers who might have thought solely of deploying new workloads on x86 servers can now consider the best fit of all these architectures toward meeting their business objectives.

Summary

For those who have been in the computing industry for a few decades, this may sound similar to the initial mainframe/dumb 3270 tube design (aka master/slave or timesharing architecture), but what STASH is doing with its new smarter terminal design (what Jim calls his thin clients) is extending mainframe virtualization management, security, and governance to a variety of underlying virtual terminal types, including x86-based thin clients, Advanced RISC Machine (ARM)-based mobile devices such as the Android, iPads, iPhones, and more. When STASH comes to fruition during the first half of 2012, mainframe customers will be able to take advantage of all the strengths of a mainframe (security, virtualization, resilience) to build highly secure, trusted virtual desktop environments.
