MariaDB and the Future of MySQL
As you may know by now, since the acquisition of Sun Microsystems by Oracle in 2009 for $7.4 billion, there has been some uncertainty in the industry on the future of MySQL which Sun Microsystems itself acquired for $1 billion in 2008. Even as Oracle professed to provide the same level of support and development effort for the future of MySQL, many within the open source community remained pessimistic. One such pessimist was the father of MySQL, Michael “Monty” Widenius, who forked the MySQL code the day the Sun Microsystems acquisition was announced. Continue reading

openSUSE 13.1 and Useful Apps
openSUSE 13.1 has been released. I just installed it on an old HP 6530b laptop without issue. Screen resolution, volume, wireless internet, and USB device recognition all seem to work without any additional mucking around. Of course things may not go so smoothly with all laptops/computers depending on the hardware, however, I’ve seen hardware compatibility improve quite a bit over the last several years. Upon booting-up it seems like all works well and my wireless network is easily picked-up. The openSUSE Linux distribution sure has come a long way and is one of my favorite Linux distributions.

Automating VLAN Configuration on Dell FTOS Switches via GVRP
GARP VLAN Registration Protocol (GVRP) is a standards-based protocol defined in the IEEE 802.1Q specification that provides for automatic VLAN configuration on switches. The Generic Attribute Registration Protocol (GARP) is used by switches supporting GVRP to register/de-register attribute values such as VLAN IDs between switches within the network. GVRP is the standards-based equivalent to Cisco’s Virtual Trunk Protocol (VTP). To read more about Cisco VTP, read my prior blog at networkpros.org. For this blog, I utilize 2 x Dell S60s [FTOS 8.3.3.8 ]and 1x Dell S50N [FTOS 8.4.2.7]. Below is the network diagram for this lab. Continue reading

Redistribution of EIGRP and OSPF in a Hybrid Cisco/Dell Network
Check out my latest blog on networkpros.org where I demonstrate redistributing EIGRP routes into OSPF and redistributing OSPF routes into EIGRP in a mixed Cisco IOS and Dell FTOS environment. Of course only the Cisco switches are running EIGRP and all Dell switches are running OSPF. A Cisco Catalyst 6509 switch chassis is running both EIGRP and OSPF, and this is where the redistribution occurs. For this lab I use 1 x Cisco Catalyst 6509 [IOS 12.2(18)SXD7b], 1 x Cisco 7204VXR router [IOS 12.2(11)T9], 2 X Dell S60s [FTOS 8.3.3.8], and 2 x Dell S50Ns [FTOS 8.4.2.7].

Dell MXL and FC Flex IOM: Enabling Network Convergence via FCoE [Video]
As you know from my prior blog, blog, the Dell FC Flex IOM adds 4 x FC ports (8 x FC ports with 2 modules) to the Dell MXL/IOA blade switch and transforms it into a NPIV Proxy Gateway (NPG) allowing for the bridging of FCoE and Fibre Channel at the switch blade level. Check-out the video here on YouTube (also embedded below) or on the Dell MXL wiki page (second video on page) that steps through the details and ease of deployment of this solution. Continue reading

Writing Useful Batch Scripts for Windows
An often overlooked utility in Windows is the use of batch scripts.A batch script is nothing but a text file with the ‘.bat’ extension containing a series of commands to be executed by the Windows command interpreter. Along with calling programs from the command prompt, branching and looping logic is also possible. In this blog, I demonstrate some useful batch script functionality; I use Windows 7 as the operating system. Continue reading

Dell PowerEdge M1000e – FlexAddressing
Dell PowerEdge M1000e as shown with detected blade servers in the Dell M1000e Chassis CMC GUI
What if you were to use the CNA port’s WWPN (World Wide Port Name) within your zoning configuration on a backend Fibre Channel switch? What would occur if the CNA adapter went bad and needed to be replaced? Well, you would have to manually change all configurations that reference the LAN MAC Address or FC WWPN. In this case, the zoning configuration would have to be updated. This is where Dell’s M1000e FlexAddressing technology can help. Continue reading
