Cisco UCS C210 in Greenplum MR Hadoop Reference Configuration Posted: 06 Jun 2013 04:39 PM PDT Major hardware components and interconnection of Greenplum MR Hadoop Reference Configuration. This diagram is a screen capture of Figure 5 of  this White Paper on Cisco.com. In fact, I shared the following content in this Google Plus Community: Using Cisco UCS. If you like to explore more about Cisco UCS, welcome to join us anytime! --- I used to say UCS C Series are designed for "smaller deployment". However, recently I found an interesting application in DCUCD v5.0 training materials,  which contradicts to what I said before. Greenplum MR Hadoop Reference Configuration is a quite-large deployment with UCS C Series only. I really should correct my saying from now on! This Reference Configuration starts from single rack: 18 sets of C210 servers. With multi-rack I believe it can be scaled up to 8 racks (144 sets of C210 servers). Why doesn't it make use of B Series? In this design it does not rely on any external storage. It only uses "locally attached storage". Maybe this is direct result of Hadoop's distributed computing architecture: failure of any node (C series server) will not fail the whole computing system. So there is no advantages even if we use more reliable, more expensive, and centrally managed storage systems. To attach a lot of local disks, C Series would be better fit!

New updates to be in Cisco ISE 1.2 Posted: 06 Jun 2013 08:58 PM PDT Jih Yueh Shan Jing Leisure Farm (日月山景休閒農場). Changhua County, Taiwan (Google Plus) I summarize the key points I learned from this Q&A on Cisco web site. [New Features] MDM Integration Device Feed Service Doubling of Scale and Performance Bootstrap Wizards Six MDM platforms are supported at the beginning: AirWatch, Good Technology, Fiberlink, MobileIron, SAP/Afaria, and Citrix/Zenprise. To update profiling patterns automatically in ISE version 1.2, we designate one ISE node with Internet connectivity to receive new Device Feed Service. This service will be available upon the release of ISE 1.2 Maximum concurrent users in 1.2 is 250,000 (before: 100,000). * Bad news: ISE version 1.2 is still not TACACS+ ready. We have to wait for a while so ISEs can replace ACSs. [New Hardwares] In version 1.2, Cisco ISE can be installed on new hardware servers: Cisco Secure Network Server 3415 and 3495. They are both based on Cisco UCS C220 box with different number of processors and memory sizes. Cisco Secure Network Server 3415 is designed for 5,000 endpoints of identity processing. Cisco Secure Network Server 3495 is designed for 20,000 endpoints of identity processing. [Reference] Cisco Identity Services Engine Q&A
