    Configure sFlows on a Brocade 8470

    sFlow is an industry standard that allows network equipment with the appropriate agents to send data to sFlow collectors, which then analyze network traffic. You can install sFlow on routers, switches, and even put agents on servers to monitor traffic. Brocade (along with most other switch manufacturers) supports sFlow. Before you do anything log into the switch and check the current flow configuration: show sFlow To configure, log into the switch and use the the int command to access an interface. From within the interface, use the following command: sflow forwarding Then exit the interface using the very difficult to remember exit command: exit Repeat the enablement of forwarding for…

    Yosemite Server: Configure Clients In Xsan 4 Environments

    Yosemite brings Xsan 4, which brings a new way to add clients to an Xsan. Xsan Admin is gone. From now on, instead of scanning the network using Xsan Admin. we’ll be adding clients using a Configuration Profile. This is actually a much more similar process to adding Xsan clients to a StorNext environment than it is to adding clients to Metadata Controllers running Xsan 3 and below. But instead of making a fsnameservers file, we’re plugging that information into a profile, which will do that work on the client on our behalf. To make the Xsan configuration profile, we’re going to use Profile Manager. To get started, open the Profile…

    iSCSI Target Creation

    The iSCSI Initiator that we use for connecting Windows to iSCSI targets has a friend.  It’s called Microsoft Windows Storage Server, which you can use to turn a DAS RAID in a Windows box into a LUN for iSCSI.  Good stuff.  Check out the data sheet here: download.microsoft.com/download/d/8/4/ d84b1c50-e0bb-45ba-b2f4-356f4f456a88/WUDSS%20Datasheet_Final.doc Now that’s not to say they’re the only game in town.  iSCSI Target is also a feature of OpenSolaris: http://opensolaris.org/os/project/iscsitgt/ And there’s a nifty little Open Source Project called iSCSI Enterprise Target: http://sourceforge.net/projects/iscsitarget/?abmode=1

    Practical ILM

    I originally posted this at http://www.318.com/TechJournal The amount of data used by Small Businesses is on target to rise 30% to 35% in 2006. Sarbanes-Oxley, HIPPA and SEC Rule 17a-4 have introduced new regulations on the length of time data must be kept and in what format. Not only must data be kept, it must be backed up and secured. These factors have the cost of data storage for the Small Business increasing exponentially. Corporations valued at more than 75 million dollars are generating 1.6 billion gigabytes of data per year. Small and medium sized companies can reap the benefits of developments being made with larger corporations. Different methods and…
