IBM Readies Update for Key Mainframe
IBM is set to unveil an update to its high-end z990 mainframe that analysts say will enhance the system’s reliability and security and bring as much as a 40% performance boost to a product that is aimed at corporate users running very large database and transactional systems.
The official announcement is expected at an IBM event in New York on Tuesday that is being hosted by Bill Zeitler, senior vice president and group executive of IBM’s systems group. An IBM spokesman declined to comment, except to say that the event is “bigger than the mainframe.”
Industry observers expect the event to focus on IBM’s larger ondemand and virtualization strategy, where the mainframe will play a key role.
“IBM continues to try to make the mainframe the center of the on- demand data center and they’re going to enhance the things they think are required in that area: security and availabilityplus providing more flexibility? says John Phelps, an analyst at Gartner.
“Their challenge is to be able to enhance it such that it can draw in other platforms and work with them,” he says.
Analysts also expect the new machines to be bigger and faster. The system will be built on engines running at 600 MIPS, analysts say. The z990 has engines running at about 450 MIPS.
In addition, while the new system isn’t expected to have more processors, end users will be able to allocate more of them to workloads so that the system can scale up to a 38-way machine.The z990 scales to a 32way configuration because some of the processors are allocated strictly for spares or system-assist functions.
During a conference call with analysts following the release of IBM’s second-quarter financial results last week, IBM CFO Mark Loughridge said that a new zSeries will be announced this week, “with availability in September.” He said that integration, security and workload management features will be enhanced in the new mainframe.
After double-digit growth in 2004, zSeries revenue has taken a hit. Revenue declined 24% during the second quarter, compared with the same quarter a year ago, caused in large part by customers awaiting the new product announcement, Loughridge said.
At the same time, workloads running on the mainframe are expanding.”About 60% to 70% of our revenue is associated with new workloads, particularly Linux, enterprise applications and WebSphere,” Loughridge said.
Joe Poole, technical director at Boscov’s department stores in Reading, Pa., runs Linux instances on a z900, and is planning to upgrade to a z990 this year.
If the new zSeries is available in September, Boscov’s may get that machine rather than the z990, Poole says. The most interesting aspect of the new mainframe is the faster processor, he says.
“Most of the software we license … is by CPU, not by speed,” Poole says. “The faster the chip, the more we benefit. If the speed increases by a third, that means we can put more work on the z/VM side and run even more Linux instances.”
IBM also is expected to put the first touches on its new networkattached storage (NAS) strategy, which the company initiated in April when it signed a deal with Network Appliance to resell and re-brand NetApp file servers.
IBM is expected to announce the new TotalStorage N3700 NAS system. The N3700 is a re-branded Network Appliance FAS270 Series file server – a mid-range system with up to 8T bytes of capacity and Fibre Channel capability for connection to storage-area networks as well as Gigabit Ethernet LANs. The system is expected to be available in August. Pricing has not been determined, sources say.
IBM also is expected to announce that it will double the cache to 8G bytes per controller on its TotalStorage DS4800 array and support 4G-bit Fibre Channel switching technology
