  • Converting CPU hours to MIPS: Mainframe capacity planning process

    In this expert tip, learn how to convert CPU hours to MIPS to aid in mainframe capacity planning.

  • Intel Xeon E5-2600 delivers eight-core CPU, more memory

    Enterprise IT shops using server virtualization now have an eight-core Intel Xeon CPU that supports more memory and broadens the use case for 10 Gigabit Ethernet. IBM, HP and Dell all introduced servers based on the new chip.

    The latest...

  • Making mainframe technology hip again

    The mainframe is a beautiful piece of technology, able to securely manage and meet the performance goals of disparate workloads for thousands of users in a relatively small, energy-efficient package. It maintains levels of compatibility and...

  • Can traditional server vendors survive the cloud push?

    Ten years from now, will we look back on the traditional server vendors like IBM, HP and Dell as dinosaurs that could not withstand the giant asteroid that is public cloud? Or will we marvel at their resourceful ability to adapt -- and survive --...

  • How a server redundancy mindset helps with capacity planning

    Is there a rule of thumb for planning for server capacity? For example, if I know that I need five "beefy" servers to handle my in-house needs, should I buy an extra one or two -- or 20% more CPU/memory than needed -- for server redundancy?...

  • Amazon boosts EC2 CPU for larger workloads

    Amazon has introduced the second generation of its EC2 computing on-demand infrastructure as a service cloud service, with higher performance processing designed for larger applications.

    The Second Generation Standard Instances offer 50%...

  • Two Linux and Unix commands you might not know you need

    What are some lesser known, but highly useful Linux and Unix commands, and what do they do?

    Throughout my time as a system administrator, I've noticed that a handful of commands are utilized disproportionately regularly, compared...

  • A deeper look at memory ranks, channels and types

    There's more to server memory than data rates. It's also important to understand memory ranks and channels.

    When selecting server memory, it is almost always best to choose registered DIMM (RDIMM) rather than unbuffered DIMM (UDIMM)...

  • The many faces of converged infrastructure

    IT vendors are riding the converged infrastructure wave into data centers by labeling their wares with the term, but it turns out that very few platforms are truly converged.

    To prepare for his session, Converged Infrastructure...

  • Comparing popular converged infrastructure products

    The market for converged infrastructure is growing rapidly as IT departments small and large decide that IT complexity is bad. Options from Hewlett-Packard, Dell, IBM, Cisco Systems, VCE and NetApp attempt to reduce acquisition and operational...
