With the release of two hi-end server beasts comes the IBM Redbooks publications take on the 5 things to know.
1. They boot amazingly quick
A new system board topology, new flexible intra-CEC cabling, and parallel processing allows multiple components to initialize from cold (no power) to ready (powered on ready for OS to boot) state. In our labs, a fully populated E880 system initialized in about 10 minutes. Of course, always test with your configuration so you know what to plan for in case of that epic power fault about to happen.
2. You are going to need Bigger Data
The new POWER8-based enterprise systems have the fastest PCIe Gen3 I/O and memory buses in the market. It means that moving data from disks to memory and crunching data is done at incredible speeds. While a single POWER8 processor can achieve up to 230 GB/s reading and writing data to memory, a whole Enterprise system has more than 3.5 TB/s of memory bandwidth and more than 1 TB/s for I/O bandwidth. At these speeds, the whole Wikipedia library (which has more than 6 TB of data) could be read from storage in less than 6 seconds and scanned in memory in less than 2 seconds. This changes the scale of what is considered Big Data for a POWER8 based system.
3. Reduce your footprint in your Datacenter
The new servers in a four CEC configuration (available in 2015) with simultaneous multithreading (SMT8) offer up to 1536 threads per system. All of this processing power fits into 22 rack units in a regular 19-inch rack using the latest power saving technologies. 19 is the new 24! Give your facilities team a good night's sleep by reducing both your space an power requirements. They look like they need it.
4. They have great I/O expansion capability
The new POWER8-based systems support a new PCIe Gen3 I/O Expansion drawers. Configurations allow up to 56 industry standard PCIe Gen3 I/O slots using the new drawers. Stop worrying about looking for a free slot the next time you upgrade and spend time doing something you really enjoy, such as posting puppy photos.
5. Amazing availability
The new Power E870 and E880 servers have redundant service processors and clocks in a trick separate enclosure. Combine this with existing POWER technologies such as Chipkill memory, dynamic processor sparing, and live partition mobility and you can be certain your workloads are on the safest platform. Heard about trickle down? You get all the benefits even if you have just one CEC.
