In Part 3a, we discussed the possibility of a purpose-driven Compute Node based on the Torrenza initiative for the Future Storage system. This expansion node made use of Hypertransport as a “glue” between the base storage compute node and the expansion node (of computation or I/O flavours) that could be added. The advantages of that topology were simple: hot add support for additional processing power, additional I/O bandwidth within the system, and additional computing power for the array OS (which we’ll cover in a later article). In this overview, we’ll take a look at another variation on an expansion node: an I/O expansion node that will add additional front-end ports and/or functionality to the base system. We will be referencing the diagram below. (Apologies in advance for the image shearing off in the lower right hand corner).
So, in my article yesterday, I gave a global view of a very simple storage system for the future. Since I LOVE this type of conjecture and theoretics (is that a word?), I decided to take this a step further and flesh out some of the other intricacies of the design. Check out the image below and then click through to read the rest.
Is it just me or have we been waiting for this for a while? 😉 Today is officially the EMC Clariion CX4 public GA (general availability) date. Good news: they’re shipping TODAY! No paper launches, folks…this is immediate availability. The other good news: you get to do more with your storage; faster, cheaper, stronger, more flexible, etc. Let me rip through some highlights for you:
a.) Cache and SP Processor increases. Across the board, processor “speeds” and cache sizes have been increased. Now, this may appear somewhat odd in that the CX4-120, for example, only has two dual core 1.2ghz processors, but, when you consider that the onboard L2 cache is greater in size (and Woodcrest processors were HANDILY more powerful than the older Nocona Xeons), it actually has more innate processing power than the previous generation processors. Cache sizes, when coupled with the 64 bit FLARE OS for the array, allow for better allocation and utilization within the array.
So, it’s been awhile since we last did one of these posts. To that end, let’s dive in and see what people are looking for these days.
No suprises here, but then again, I can’t talk about the CX4 just yet. Suffice it to say, I’ll be prepping a few auto-posts on the CX4 (and another product that may be announced during the same timefram) to give you a high level overview of such. There IS a post out there @ Block and Files that is somewhat correct but….somewhat off. 😉 You’ll get the “truth” on Monday.
Obviously I’ve been missing in action for several weeks, but I promise you, it was for good reason(s). There was the end of fiscal Q2, 2008 here at EMC, subsequent re-assignment of territories, and *drumroll please* VMWare Certified Professional training class. That last item is personally one of the greatest things that I’ve had to deal with in the months at EMC and I’m looking forward to laying it all out for you in the coming weeks.
In the near term, however, there are two REALLY exciting things coming up in the next week or two. At this point, you’ve heard the rumours (undoubtably about “new” product coming) and I just want to say that, given my early look at these offerings, SMB will be MIGHTILY impressed with at least one of them. 😉 Not to slight the second announcement at all, but this first announcement is specifically targeted at one of the largest gaps in SMB product that EMC offers today (hint: think about multi-protocol on the cheap). I’ll reveal more (probably next week or so) but for now, I’m excited.
This is the second edition of the same post. Evidently, WordPress doesn’t like it when I fat-finger in Firefox 3.0 Beta 5. Grrrrr…..
So, what is “Search Term Tuesday” (or any other day of the week, even)? The principle of it is this: grab some of the focused searches out there that land on this site (i.e Flickerdown) and attempt to respond to them with more data. Deal? Let’s begin, then.
It’s no secret that Microsoft’s SQL database environment is immensely popular in the market. To that end, EMC and Microsoft have developed “Best Practices” for laying out SQL databases, logs, quorums (for clustering), and TempDb on our arrays. For this entry, I thought I’d provide you with a quick overview of two different disk layouts.
