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.
I’ve written a few times about my quest to build the ultimate home storage/server rig. But one issue was surprisingly vexing: What kind of case has room for a dozen or more hard disk drives? In this update, I’ll talk about the various options as well as the one I ultimately picked: The NZXT H440 (and a Corsair power supply).
Today I’m going to dive into the hardware I selected for FreeNAS, starting with the motherboard, CPU, and memory. FreeNAS runs on any PC hardware, but building a reliable and scalable storage solution means picking higher-end components. I selected a Supermicro X10SL7 server-class motherboard with 14 (!) SAS/SATA ports paired with an Intel Xeon E3-1231v3 (Haswell) CPU and ECC memory from Crucial.
Long-time readers of my blog know of my love for Drobo, but the time has come to say goodbye. My old Drobos (and Iomega ix-4) are showing their age and I decided to go in a different direction: I’m building a FreeNAS server. In this article I’ll talk about my thinking behind this move; later posts will talk in more detail about the hardware and software setup.
Although not discussed in today’s keynote, Apple is adding a new “universal” filesystem to iOS and macOS. Apple File System (APFS) will likely replace HFS+ as the default filesystem for Macintosh computers, iPads, and iPhones and brings a wealth of modern features. But judging from the initial developer documentation, that’s not going to happen for a few more years. And there’s still much confusion about how APFS and CoreStorage, introduced in Mac OS X 10.7, will interact.
I’ve really enjoyed experimenting with the Raspberry Pi, and have even deployed a few as UNIX servers in my home and office network. The quad-core performance of the latest Pi models is awesome, but serious I/O limitations remain. With just one USB 2.0 interface shared for all network and storage operations, you aren’t going to […]
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 […]
I’ve got fond memories of St. Louis, having lucked into a ticket to the 2011 World Series. Now I’m back twice in two weeks, presenting at the VMUG User Conference and TechTarget Seminars!
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!
