Continuing with my current theme of Fibre Channel over Ethernet, and at the request of several people, this post will take a close look at Converged Network Adapters (CNA). Now then, there is no easy way to put this, but to do justice to a topic like this will require a lot of words. I’ll [...]
The early part of this week saw me attend a specialised Tech Day at HP Colorado Springs that revolved around Data Centre Convergence with an emphasis on HP Storage. I have to say that the event was a rip roaring success and I would highly recommend other vendors do the likewise. Aside from the excellent [...]
Amid all the discussion of FCoE and the many requests to cover more aspects and underlying technologies, I thought it probably a good idea to take a step back for a moment and recap flow control in native FC networks. After all, FCoE is almost a transplant of FCP onto Ethernet. Granted, to some people [...]
In keeping with my current focus of attempting to shed some light on FCoE and help people learn and realise some of the beneits, the link below is to a video that Cisco will be putting up tomorrow (10am PDT). Its an interview with Sr Director of IT at the University of Arizona, where they [...]
Ewan Leith (@ewantoo) asked if I could whip something up re cables and infrastructure required for FCoE (DCE/CEE). So here goes. I think there has been a lively discussion on FCoE over the last 24-48 hours and it would be good to keep it going…… Before I start I’d be interested in any feedback, updates [...]
Following on from Hu Yoshidas apparent blunder over FCoE and lossy networks, I thought I’d do my bit to clear things up and shed some light. Knowing a thing or two about FCoE I’m regularly amazed at how little some people know……. So the following is a mini tutorial on the flow control and lossless [...]
UPDATE: I have removed this post due to glaring innacuracies – I trusted my engineer (never again!!) and didnt do my background checking. Apologies and no harm intended.
Below are some notes to the above videos (especially for those in quiet offices who can’t watch the video yet). I posted the video in response to Marc Farleys recent video and comments on Hitachi Dynamic Provisioning, as well as other comments that have been made in blogs and on twitter etc….. All of these comments [...]
This post is for anyone interested in Hitachi storage who feels like they’ve had enough HAM for a lifetime and just wants a taste of something different for a change…. One of the projects I’m currently working on involves deploying a new USP V with native SATA disks side-by-side with FC disks (when I say [...]
Well there has been a lot of confusion the past couple days about the latest announcement from HDS about clustering of the USP-V. I hope to clear up some of the technical details with this post, but I’m sure there will be some questions that remain. First, lets talk about why someone would want to [...]
Some very early thoughts on yesterdays clustered storage arrays announcement – Hitachi High Availability Manager, or HAM for short. <this was written while watching the Champions League final and twittering last night so more info might have emerged since I wrote it> Where I come from in the world, "ham" is pig meat. Let’s hope [...]
Was just thinking through some of the newer storage tech today while driving to and from a customer. It is widely expected that HDS is going to announce the availability of their clustering of the USP-V line of boxes tomorrow. We know that the technology has been built into the microcode and hardware since the [...]
Off topic, but a most worthy cause! This is the most important content that has ever been, or probably ever will, be posted on this site……. Nick Glasgow, an EMC employee is dying from Leukaemia and is in desperate need of a bone marrow donor of caucasion-asian ehtnicity. Please go to Mark Fredrickson’s blog to [...]
UPDATE: Version 0.003. Updated info on Hitachi, HDS, HP and SunCorrected some typos, clarified some points and corrected some mistakes. v0.002 updates: Updated content includes section on RAID6 contributed mainly by Devang Panchigar at http://storagenerve.com/ as well as content on RAID1 and HDP 42MB Page size.As a result of feedback relating to the HDP unofficial [...]
Find the new release here. I think this is awesome news for Sun. This will keep what they have going strong and streamline some of that are on the fringe. I think Ellison summed it up best here: "The acquisition of Sun transforms the IT industry, combining best-in-class enterprise software and mission-critical computing systems," said [...]
Since I’m recovering on the couch from a small operation and therefore with time to spare I thought Id join the throng in commenting on Symmtrix V-Max…. For perspective – At the time of writing, I don’t work for EMC and I don’t work for any of their competitors. My own area of expertise is [...]
I see Snig has also posted on this topic earlier today and made some interesting points and there may be some overlap…. no harm though. I started writing this post a few weeks ago as a knee-jerk to Ciscos Unified Computing announcement, but scrapped because it got too long. Todays rehash of the same thoughts is hopefully [...]
I’ve been at SNW all week trying to find out why an end user would want to implement FCoE. Every time I write about it I get a number of vendor responses saying that I’m wrong and that it’s coming and that FCoE will rule the world. Everyone will adopt it and I might as [...]
I saw this over on FailBlog today and had to post it. Enjoy!
As a techie I occasionally come across a technology that I really like, or like the sound of. One such technology is Enterprise Flash Drives/Solid State Drives . I really want to get my hands one some and deploy them in anger. Almost to the point where I would shoehorn it in to a solution [...]
