Building fast erasure coded storage

July 11, 2016

One of the decade’s grand challenges in storage is making efficient advanced erasure coded object storage (AECOS) fast enough to displace most file servers. Advanced erasure codes can give users the capability to survive four or more device failures – be they disks, SSDs, servers, or datacenters – with low capacity overhead. By low I […]

The top storage challenges of the next decade

July 6, 2016

StorageMojo recently celebrated its 10th anniversary, which got me thinking about the next decade. Think of all the changes we’ve seen in the last 10 years: Cloud storage and computing that put a price on IT’s head Scale out object storage. Flash. Millions of IOPS in a few RU. Deduplication. 1,000 year optical discs. There’s […]

July 4th, 2016: Mormon Canyon

July 4, 2016

July 4th is when the United States of America celebrates the signing of the Declaration of Independence. For most Americans Independence Day is the most important secular holiday of the year. Of course, July 4th wasn’t the actual date of the signing – July 2nd was – but no matter. Of greater interest is the […]

Meeting young Mr. Trump

June 30, 2016

Back in 1980 I met Donald Trump. He came to a finance class to talk about real estate finance. I have no recollection of his talk. But I DO remember the visit and, given what I’ve read about Mr. Trump, some readers may find my recollection an interesting footnote. Ivana To set the scene, this […]

Enterprise storage goes inside

June 20, 2016

Some interesting numbers out of IDC by way of Chris Mellor of the Reg. First up: the entire enterprise storage market in the latest quarter: Note that HPE is #1. Then the numbers for the external enterprise storage market: HPE is now #3 with $535.7 million. The difference is internal storage That means that HPE […]

Hike blogging: Hog Heaven trail

June 12, 2016

Mountain biking is very popular in the surrounding national forest. Enthusiasts have built many challenging bike trails, which I like to hike – not bike. I’ve never broken a bone and don’t intend to start now. Hog Heaven is one of the toughest of the local trails, with a double black diamond rating. Yesterday morning […]

EMC perfumes the pig

June 10, 2016

I feel sorry for EMC’s marketers: they have to make 10-20 year old technology seem au courant. It’s an uphill battle, but that’s why they get the big bucks. The latest effort to perfume the pig – hold still, dammit! – is EMC Unity. In a piece that – and this is a sincere compliment […]

Commoditizing public clouds

June 8, 2016

I’m a guest of Hewlett-Packard Enterprise at Discover 2016 in Las Vegas, Nevada this week. I enjoy catching up with the only remaining full-line computer company. HP was a competitor in my DEC days, and since the Compaq purchase they incorporate the remains of DEC as well. One of their themes this year is multi-cloud […]

Thunderbolt: a fast and cheap SAN

June 2, 2016

If memory serves – and mine often doesn’t – I asked a panel at the NVM Workshop at UCSD their opinion on using Thunderbolt as a cheap, fast, and flexible interconnect. After all, I thought, academics always need more than they can afford, so these guys would have been looking into it. Nope! They laughed […]

Hike blogging: Memorial Day 2016

May 31, 2016

Yesterday I took a seven mile out-and-back hike along the Chuckwagon Trail. This is an area I want to explore more. It didn’t look like a good day for pictures, so I didn’t take the Canon EOS-M. But the smoke from a couple of burns on the Rim cleared and some nice clouds appeared, so […]

The array IP implosion

May 23, 2016

We’ve seen this movie before The value of legacy array intellectual property is collapsing. This isn’t complicated: SSDs have made IOPS – what hard drive arrays were optimizing for the last 25 years – easy and cheap. Think of all the hard-won – well, engineered – optimizations that enabled HDD-based arrays to dominate the storage […]

WD is not a disk drive company – and not a moment too soon

May 20, 2016

While you weren’t looking Western Digital stopped being a hard drive company, morphing into a storage company. Such transitions are nothing new for a company that started life making calculator chips in the 1970s, morphed into SCSI, ATA and graphics in the 80s, and built its disk drive business in the 90s and 00s. The […]

Scale and the all-flash datacenter

May 9, 2016

There’s a gathering vendor storm pushing the all-flash datacenter as a solution to datacenter ills, such as high personnel costs and performance bottlenecks. There’s some truth to this, but its application is counter-intuitive. Most of the time, storage innovations benefit the largest and – for vendors – most lucrative datacenters. OK, that’s not counter-intuitive. But […]

Why storage is getting simpler

May 2, 2016

Goodbye, old bottleneck StorageMojo has often asked buyers to focus on latency rather than IOPS thanks to SSDs making IOPS cheap and plentiful. This naturally leads to a focus on I/O stack latency, which multiple vendors are attacking. But what are the implications of cheap IOPS for enterprise data center operations? That’s what’s motivating the […]

Storage surprises at NAB 2016

April 22, 2016

I did NAB a little differently this year: attended on Wednesday and Thursday, the last two days of the floor exhibits. Definitely easier, although many of the execs left Wednesday. But that wasn’t a surprise. Here’s what did surprise me: EMC seemed to have less of presence than in past years. I expected more. HGST […]
