Optimizing erasure-coded storage for latency and cost

September 12, 2014

Erasure coded (EC) storage has achieved remarkable gains over current RAID arrays in fault-tolerance and storage efficiency, but the knock against it is performance. Sure, it’s highly available and cheap, but it’s slo-o-w. Advanced erasure codes – those beyond traditional RAID5 and RAID6 – require a lot more compute cycles to work their magic than […]

Friday hike blogging: Teacup Trail

September 5, 2014

This view of Coffeepot Rock is from Teacup Trail. This is a more heavily traveled area as it’s close to town, the trails are easy – except for Thunder Mt. Trail, where a friend died last year – and the scenery is great. Enjoy!

Deep file analytics

September 5, 2014

A new storage market is being born. Will it survive? As infrastructure continues to adjust to a data-centric world, the ability to manage data – not just storage – is poised to become a must-have capability. Traditionally, of course, data management has meant databases. But file data – confusingly called unstructured data – is by […]

Infinidat: 21st century enterprise storage arrives

September 3, 2014

Who would have thought, at this late date, that an upstart would appear to challenge high-end EMC, NetApp, HDS and IBM arrays with a fundamentally superior product. But when you don’t have an installed base – and a cash cow – to protect, you can go big. That upstart is Infinidat. Read on and see […]

Labor Day 2014

September 1, 2014

The brutal struggles of Capital and Labor in the 1800s may seem far away in 2014, but they continue to this day. Now there’s less blood, but a good deal more money. Why do we have a Labor Day? Wikipedia says: Labor Day in the United States is a holiday celebrated on the first Monday […]

Friday hike blogging: Airport Mesa

August 29, 2014

Often named as one of the most scenic airports in America, the airport sits on a mesa high above the town. There’s a trail that circles the mesa and – more important for me – I can walk to it. According to my iPhone app, the hike is 7.22 miles with 1788 feet of vertical […]

The network crunch: DAS and SAN

August 28, 2014

Several years ago an Intel briefer promised me $50 10Gb Ethernet ports. The shocker: prices have dropped little in the last 8 years – well more than a decade in Internet time. I don’t look back as often as I should. But a note from a ZDNet reader prompted some retrospection and research into network […]

Why are array architectures so old?

August 25, 2014

25 years ago I was working on DEC’s earliest RAID array. When I look at today’s “high-end” arrays, it’s shocking how little architectural change the big iron arrays have embraced. The industry is ripe for disruption, only part of which is coming from cloud vendors. 21st century problems demand 21st century architectures. Here’s a list […]

Friday hike blogging: clouds!

August 23, 2014

There’s a reason Arizona doesn’t have Daylight Saving Time: we have as much daylight as we can stand. With over 300 sunny days a year – and the sunniest are often the hottest – it’s a relief to see the sun set as the perceived temps drop 10-15°F. Despite that, summer is my favorite season […]

Friday hike blogging: Mormon Canyon

August 15, 2014

After several days where I couldn’t get out I left at 6am for my favorite hike, the Cibola-Jordan-Soldiers Pass-Brins Mesa loop. Big decision: clockwise or counter-clockwise? Clockwise is gentler with an uphill bias until reaching the highest point – 5138 feet – after 4.5 miles. Counter-clockwise gets the bulk of the vertical done in the […]

Scale Computing: infrastructure made simple

August 15, 2014

Google and Amazon have armies of PhDs to design, manage and diagnose their scale-out systems. Few small to medium sized businesses do – nor should they – but they should still have the advantages of scale-out infrastructure. Imagine infrastructure that comes in a box with no costly VMware licenses, great support and good scalability. That […]

Got interoperability testing?

August 9, 2014

At Flash Memory Summit StorageMojo spoke to David Woolf and Kerry Munson of the University of New Hampshire InterOperability Lab. It’s been around for decades and still is. It is primarily staffed by college students – cheap labor – managed by senior engineers. Protocol testing is it’s primary function. The IOL tests many protocols such […]

Seagate’s Kinetic vision shipping – but not from Seagate

August 4, 2014

Remember Seagate’s Kinetic open storage vision? Turns out there is a shipping product embodying the same ideas – but not from Seagate. Surprised? Huawei’s UDS – Universal Distributed Storage – system launched two years ago with a home-grown smart disk. Each UDS drive has a daughter board with an ARM processor, memory, two Ethernet ports […]
