July 2008 Newsletter


We hope you are enjoying your summer and perhaps taking a little vacation time as well.  It has certainly been quite a busy summer for us with lots of new Power 6 520s, and Power5+ 515 and 525s being installed.  In addition, new customers are coming out of the closets asking us to do i5/OS upgrades to V5R4.  Many of our existing customers are upgrading to IBM i 6.1.

This issue of our newsletter has four articles.  In the first, we’ll take a look at automatically setting the time on your machine. As performance is an issue in most shops, our second article deals with the number of disk arms on your system.  The third article deals with having a UPS since the summer is always a time for brown-outs and black-outs. The last article is for your reference with updated PTF information for your use.

iTech Solutions can help you improve performance, upgrade i5/OS, perform security audits, implement a High Availability solution, VoIP, Systems Management, PTF management, Blade installations, iSCSI Configurations, upgrade an existing machine, or upgrade to a new machine.  If you are thinking of LPAR or HMC, then think iTech Solutions.  We have the skills to help you get the most out of your System i.  For more information on any of the articles below please visit us at iTech Solution or contact us at [email protected] . We would also like to know what you think of this newsletter and any items you would like us to discuss in future issues.

Who has the Time?? 
I was in a customer’s data center the other day, and I overheard the operator mumbling under his breath, “Every *&^% machine has a different time, how am I supposed to match events on these machines?”.  I thought I would go over and talk to him.  I asked him if he had ever heard of Network Time Protocol.  I had to duck, as I thought he was going to throw the clock at my head.  I hung around and explained it to him, that the Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched TCP/IP networks. NTP uses UDP port 123 as its transport layer.  On i5/OS we can configure TCP/IP to use Simple Network Time Protocol (SNTP) to adjust our time to keep all our machines with the same time or even
