Capital budgets are pretty tight this year and IT teams all over the globe are being to do more with the same or less. This is good in many ways and hopefully we will overcome some of the profligacy of the past but the responsibility is in our (the end-users) hands, we canâ€™t simply expect the vendors who have encouraged of profligacy in the past to come riding to our rescue.
The announcements are starting to pile up; nothing dramatic yet tho’ but we are probably at the start of the year when most Storage vendors refresh their main product lines and it’s going to be interesting to see the variety…
Today, Brocade announced that it has completed its acquisition of Foundry Networks. This is just the latest move in the strategic game to control the next generation of Ethernet, and possibly all local connectivity, including storage. Although 1 Gb Ethernet, 4 and 8 Gb Fibre Channel, and InfiniBand are all still going strong, the attention of the industry, the pundits, and the prognosticators (myself included) is firmly fixed on enhanced 10 Gb Ethernet. So Brocadeâ€™s move seems especially relevant to the core question of which companies will thrive and which will fail in a 10 Gb world.
Virtualization of IT systems decouples physical infrastructure from logical resources, hiding complexity and enabling new capabilities. However, not all potential benefits of virtualization have meaningful value outside IT circles: Too many of our discussions revolve around the very complexity that virtualization technology should be hiding! True business value is derived from transformed virtual resources in the next-generation data center, not the incremental capacity gains of virtual servers. But how will we get there, and what will this future look like?
All enterprise storage arrays â€œemulateâ€ Fibre Channel drives to one extent or another, and using the wrong tool for the job will always lead to trouble.
One of my projects involved the configuration of GRE (Generic Routing Encapsulation) tunnels, encrypted by IPSec, between two locations. I was having some problems getting the tunnels to work properly, but now I’ve managed to resolve that problem, and the configuration is working well. Here’s some additional information on the problem and how it was finally corrected.
