I like ZFS Send and Receive, but I’m not totally sold on it. I’ve used rsync for decades, so I’m not giving it up anytime soon. Even so, I can see the value of ZFS Send and Receive for local migration and data management tasks as well as the backup and replication tasks that are typically talked about.
Have you ever wondered if mounting a hard disk drive on its side or even upside-down affects its lifespan or reliability? According to every drive manufacturer, it’s perfectly acceptable to mount a hard disk drive in any orientation as long as it’s not tilted and has sufficient cooling.
Last week I headed to Austin, Texas to attend the semi-annual OpenStack Summit there. Along with the usual socializing, I was looking to understand the current state of the technology: What does OpenStack really mean these days, and where is it going? Let’s start with “free”. As “the Internet” is quick to point out, this critical word has multiple […]
It took longer than I expected for Nimble Storage to introduce an all-flash array, but their AF7000 looks to be a very credible offering. They’re targeting XtremIO and Pure with their marketing, but I expect HP, Dell, and especially NetApp to be cross-shopped more frequently. In that fight, I expect the Nimble AF7000 to be very attractive indeed!
I’m really excited about the prospects of memory-addressable flash. Moving flash closer to the CPU and addressing it as memory rather than block storage brings tremendous performance benefits, and is a once-in-a-generation radical change to system architecture. But questions remain as to how it can be integrated with today’s applications. Now Plexistor is here with a promising solution: Their “Software-Defined Memory” concept is a generic filesystem for storage, from NVDIMM to NVMe to SSD.
Too many marketers and salespeople play fast and loose with words, but they’re only hurting themselves. Improper usage is embarrassing and causes a loss of credibility with the people they most want to reach. It would be wise to spend a lot more time being correct and a little less time jumping on bandwagons and buzzwords!
Microsoft’s place in the datacenter is secure, and Windows Server really hums with SMB 2/3 storage. The enterprise storage industry needed an alternative to Samba and do-it-yourself SMB servers, and it’s good to see Visuality Systems step up with NQ Storage. Although I have not seen it in action, their OEM claims sound good and their roadmap looks right.
A few years back, I wrote an immensely-popular series of blog posts outlining the four things that were holding storage system performance back, and the ways to fix them. At the time, I created some presentation content to go along with these posts, and even considered pulling them into a white paper, but nothing came of that. Now, however, I’m pleased to announce that my Four Horsemen are accompanying me to the stage November 10, 2015 at the DeltaWare Data Solutions Emerging Technology Summit in Edina, Minnesota.
I’m not a stock analyst, and this is merely my own quick calculation, but this doesn’t seem like a good deal for shareholders. Dell walks away with a huge amount of value and shareholders are left hoping for the best. No wonder shares of EMC are still well below the alleged “$33.15 per share” offer price! Right now, it looks like they’re valuing that VMware tracking stock at only $4 per share, not the $9 Dell hoped.
I’ve talked a lot about the I/O blender in the last decade or so.[1. I’ve even been told I invented the term!] I’ve always said that information is the solution, allowing arrays to de-multiplex data. But a new enterprise storage company, Infinidat, claims that they can beat the I/O blender using math. Here’s their concept.
