My FreeNAS Build: Supermicro X10SL7, Intel Haswell Xeon, ECC RAM

August 4, 2016 by Stephen 2 Comments

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.

Hello FreeNAS! Goodbye Drobo and Iomega…

August 3, 2016 by Stephen 6 Comments

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.

Here’s Something Your Raspberry Pi Can’t Do: Gigabit Ethernet and SATA in the Olimex A20-OLinuXIno-LIME2

May 25, 2016 by Stephen 3 Comments

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 […]

What Is A UASP Storage Enclosure?

December 7, 2015 by Stephen 3 Comments

UASP has a lot of promise, bringing SCSI performance and features to the ever-expanding world of USB storage devices. But support has been haphazard, especially for Mac OS X and Linux, and this limits its impact. It would be nice if storage vendors could work with operating system developers to better support this storage protocol.

How To Connect a 4K Monitor to a 2012 Retina MacBook Pro

November 9, 2015 by Stephen 79 Comments

4K video is still in its infancy, but Mac users are clamoring for high-resolution external displays. Many Macs have the ability to drive a 4K display, but it’s not easy to get it to work with older hardware. Here’s how I connected a 4K Dell P2715Q display to may 2012 Retina MacBook Pro, one of the first 4K-capable Macs.

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

The Four Horsemen of Storage System Performance: The Rule of Spindles

August 25, 2010

Why do some data storage solutions perform better than others? Mechanical performance, RAM caching, I/O capacity, and the intelligence of the system all have a part to play. Today we examine the rule of spindles: Adding more disk spindles is generally more effective than using faster spindles.

Fasting to Mitigate Jet Lag: Surprise! It Works!

February 11, 2013

I’m a frequent traveler, and thus a frequently suffer from moderate jet lag. It’s just so hard to adjust to a new time zone! But I recently stumbled on a simple method many claim helps your internal clock re-calibrate to travel. After trying it out on my trip to Australia last week, I’m convinced it can help!

The Terrifying True Story Of Virtual Machine Mobility

December 22, 2011

Virtualization of server, network, and storage services illuminates the link between physical resources and functional applications. A running virtual machine can instantly move from one server, network adapter, HBA, or LUN to another. And when it happens, traditional components have no idea how to react.

Download My Free E-Book, “Essential Enterprise Storage Concepts”!

April 4, 2017

I’ve got a lot to say about storage, as you might have noticed from reading my blog. So I finally sat down and wrote a book on enterprise storage. Now you can download the e-book for free, thanks to support from my friends at SolarWinds!

Debit or Credit? Always Choose Credit!

December 19, 2013

“Credit of debit?”ï»¿ It’s all very confusing for American shoppers. But the news about a massive point-of-sale data theft at Target makes one thing very, very clear: Always choose “credit” when the cashier asks!

Deduplication Coming to Primary Storage

September 16, 2008

Although deduplication of storage is nothing new, with Data Domain and other making hay with the technique for years, it has never been ready for prime time – reduction of active primary storage applications like email and databases. Instead, deduplication has been relegated to second- or third-tier status, deduplicating archives and backup data. But change is in the air, and deduplication vendors are starting to bustle towards the bright lights of primary storage.

Regarding My Symbolic Links and Good Reads

April 16, 2015

I’ve been told that my shares drive traffic to the blogs I read. I’m thrilled that I can share great writing with you in this way, and I hope you find it valuable! But just in case you don’t, I hope you’ll take advantage of the fact that I filter these posts for you into “Symbolic Links” and “Good Reads” so you’ll find it easier to ignore them.

Cisco’s Trojan Horse

September 15, 2014

Industry watchers like me have long wondered when Cisco will transform itself into a full-line IT infrastructure vendor. This strategy was tipped in 2009 as Cisco barged into the server market with UCS. But one leg of the stool is still missing: Storage remains the province of Cisco partners like EMC and NetApp.
