Silver Bullets: Why System z?
- 25 of the top 25 WW banks1 run on z
- 23 of the top 25 US retailers2 run on z
- 9 of the top 10 global life/ health insurance providers3 run on z
- 64% of Fortune 500 (US) are System z clients
- 45% of Fortune 1000 (US) are System z clients
- 71% of Fortune Global 500 are System z clients
- 80% of world's corporate data resides or originates on mainframes.
- 2/3 of business transactions for US retail banks run directly on mainframes
- A mainframe averages decades between server outages4
- The mainframe is one of the most secure servers on the market - a 16-way z990 can securely process 12,000 transactions per second.
- Mainframes act as a centralized repository of encryption keys to facilitate security management. Each Crypto Express 2 can handle up to 6,000 SSL handshakes per second, which equates to up to 48,000 SSL handshakes per second (there are 8 of these in a z9 box)5.
- A single z series server can run thousands of virtual Linux servers
- System z is designed to deliver application availability up to 99.999% which equates to approximately 5 minutes of downtime in a year on an average
- System z9 allows scalability in processing power to up to 54 processors in a single server
- The mainframe was the first IBM server platform to announce support for Linux (May 2000)
- There are more than 1300 ISVs running on System z today
- More than 275 ISVs sell over 800 Linux applications on System z
- The cost per user (HW, SW & maintenance costs) over a 5 year period for the mainframe is $4,500/user; PCs are nearly twice as expensive at $8,000/user. If the number of users is doubled, the costs jump 125% on a non-mainframe, and only 90% on a mainframe6.
- 66% of mainframe capacity shipped today comprises of "new workloads," including Linux, WebSphere, SAP and other leading enterprise business applications.
- Introduced only in late 2000, Linux on the mainframe has already grown to approximately 20% of mainframe capacity shipped.
- The IBM mainframe experienced 28% growth in capacity YOY in Q4 2005, the largest revenue gain for the mainframe since it came roaring back in Q4 98 --- with the largest shipment of capacity in history.
- IBM began shipping the System z9 on September 16, 2005 , which represents a three-year, $1.2-billion development effort encompassing 5,000 IBM engineers, software developers and security experts from around the world
- Since 2000, the mainframe has captured 17 points of market share in the high-end server category according to IDC.

- As per IBM HW MTBF number
- Theoretically correct; however this has never been measured or validated. Also, a high capacity z9 is required to get near this number
