3 3 “IT-Equipment worldwide is responsible for 2% of C02 emissions which corresponds to the amount of CO² emitted by airplanes.“ Simon Mingay, Gartner “For approx. each $1 spent on computer hardware, further $0.5 need to be spent for electricity. Within the next 4 years, this number will rise by 54%.” IDC, Worldwide Server Power and Cooling Expenses “Only one search request at Google consumes as much energy as an energy saving lamp per hour.“ Die Zeit, August 2007 Green IT is vital - for the environment AND for costs

5 5 Στην Ελλάδα Οι προδιαγραφές αρκετών έργων εξακολουθούν να επιμένουν σε αύξηση της ενεργειακής κατανάλωσης Εμμονή σε προδιαγραφές για 400 W τροφοδοτικό σε PC !!! Προδιαγραφές για μεγάλες τροφοδοσίες σε εξυπηρετητές Προδιαγραφές κλιματισμού χωρίς ουσιαστική μελέτη αναγκών Μήπως αυτού του τύπου οι προδιαγραφές, θα έπρεπε να πάρουν υπόψη τους πλέον το περιβάλλον......

11 11 PCs τελευταίας τεχνολογίας Intel vPro Technology delivers significant Power Reduction New Intel Core 2 processors and chipsets with reduced power consumption Active Management Technology enables network administrators to remotely switch off PCs at night Source: Intel 1. Intel® Core 2 Duo processor E6xxx sequence, September Intel® Core 2 Duo processor E6x50 sequence, August Intel® Q965 Express chipset with ICH8-DO, September Intel® Q35 Express chipset with ICH9-DO, August 2007

12 12 Ομως... Currently Intel’s vPro offers the leading management technology with sophisticated functions for saving energy However: in heterogeneous PC environments (vPro and non vPro) there are no management standards Recommendations  usage of a variety of management tools in a transition phase  setting an internal standard for one technology when purchasing new PCs  usage of a “managed services” offer for the PC infrastructure. Experts will solve all the details regarding energy reduction

14 14 Use case: Terminal Services Number of servers required for 2500 users  20 x PRIMERGY RX300 S2 Server (Single Core)  8 x PRIMERGY RX300 S3 Server (Quad Core) 60+ % less energy consumption with same number of users through modern multi-core systems based on Intel architecture Performance per watt ratio is 7 to 8 times better with quad-core CPUs Servers τελευταίας τεχνολογίας

15 15 Οι εφαρμογές έχουν σημασία! Terminal server software is designed to run optimally on a multi-core architecture Many applications in the Windows world are still “single-threaded” - they can only use one CPU core „Single-threaded“ applications do not scale when adding CPU cores „Single-threaded“ applications have to be re-written to take full advantage of multi-core CPUs Ομως...

18 18 Virtualization at HypoVereinsbank, Germany Challenge: Consolidation of 650 servers Reduction of floor space and energy costs Solution: Deployment of virtual machines on about 45 PRIMERGY blade servers with VMware ESX Customer Benefits: Energy savings of 1.2 million kWh per year (120 k€) Increased flexibility through on-demand usage of computing resources Παράδειγμα

19 19 Virtualization helps saving energy, but … Not every application is a good candidate for virtualization  Be careful with performance hungry applications like MS Exchange, terminal services or larger databases with several thousands of users What about official ISV support of applications for a dedicated virtualization platform?  ISV support for different virtualization platforms can vary heavily Costs of virtualization (licenses, management, training) can eat up large chunks of savings Do I have to introduce additional systems for high availability? Ομως...

21 21 Architecture Operating system and application image on central storage On-demand provisioning to servers Benefits Flexible resource usage Save 30+ % of unused server capacity through pooling Available solutions  FlexFrame for SAP  FlexFrame for Oracle  FlexFrame Infrastructure Dynamic Resource Manager App. Server- Pool Network Storage- Pool Applications Operating Systems Save energy through server pool architectures

22 22 Transition from Oracle on UNIX to a Linux-based x86 server pooling architecture Save energy with “FlexFrame for Oracle” Less energy consumption through less servers due to pooling architecture latest x86 dual / quad-core systems  better performance/watt energy efficient redundancy  many production servers sharing few spare servers switch-off of unused servers Calculation of a customer

23 23 Server pool architectures help saving energy, but … Does it fit to the application design?  Does the application scale in a scale-out environment? How does the ISV license model support server pool environments? Server pool architectures require introduction of SAN/NAS infrastructures with high-quality central storage systems Ομως...
