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 […]

Friday hike blogging

August 1, 2014

Looking northwest from Hangover Trail on Wednesday. Hangover is a new trail that I’d never been on before. An incredible hike. I’m going to limit hike blogging to Fridays. But next week I’ll be at the Flash Memory Summit and won’t be hiking – at least not at home.

High performance SSDs: hot, hungry & sometimes slow

July 25, 2014

Anyone looking at how flash SSDs have revolutionized power constrained mobile computing could be forgiven for thinking that all SSDs are power-efficient. But they’re not. In a recent Usenix HotStorage ’14 paper Power, Energy and Thermal Considerations in SSD-Based I/O Acceleration researchers Jie Zhang, Mustafa Shihab and Myoungsoo Jung of UT Dallas examine what they […]

Performance: IOPS or latency or data services?

July 23, 2014

Unpacking the data services vs performance metric debate. Why we should stop the IOPS wars and focus on latency. IOPS is not that important for most data centers today because flash arrays are so much faster than the storage they replace. That’s why the first post was titled IOPS is not the key number. The […]

StorageMojo’s Chief Analyst will be chairing Session U-2: Annual Update on Enterprise Flash Storage. That’s on Tuesday, August 5th, at 9:45. Who knows, maybe there […]

The new storage industry rave

July 17, 2014

It used to be so simple: EMC, NetApp, Hitachi and the captive storage businesses of systems companies. Add in some fast running startups, such as today’s Nimble, Nutanix and Avere, to keep things interesting. But no more. While the startups will require several more years before they make a dent in the big boy’s businesses, […]

Hike blog: Airport loop

July 15, 2014

Walked over to the Sunset trail and thence up to Airport Mesa. This view is looking south from the east side of the mesa. This is my favorite time of year due to the monsoon – rainy season – clouds. Probably have a thunderstorm later today. And yes, there’s an airport on top of the […]

Quasi-NVRAM using built-in battery backup

July 14, 2014

Note, a version of this post appeared this morning on ZDnet. Given that roughly a billion battery-powered computers are sold each year, you’d think that the engineers would be busy rearchitecting the storage stack to take advantage of built-in – and usually non-removable – battery backup. But no-o-o! Recently three researchers, Hao Luo, Lei Tian […]

TwinStrata buy makes it official: cloud gateway a feature, not a product

July 10, 2014

EMC buying TwinStrata to put on VMAX. The StorageMojo take First of all I hope Nicos and John made out like bandits. Not likely without a bidding war – I haven’t heard of one – but they did a good job building TS. One of the attractions for EMC is that TS supports many clouds. […]

Hike blogging: July 4th, 2014

July 5, 2014

A new hike on July 4th. Hiked around Twin Buttes, about 7-8 miles. Heavy cloud cover heralding the start of the summer monsoon season. Finally got some sun breaking through the clouds and took this picture looking south. Courteous comments welcome, of course. Readers, what say you on hike blogging? Like, don’t like, don’t care?

Data services more important than latency? Not!

July 3, 2014

Yesterday’s post on IOPS vs latency provoked some controversy on Twitter. Kappy, CTO of a midwestern IT consultancy, asserted @storagemojo Most AFA users don’t even care about latency. Sure there are latency sensitive apps, but data services are more important. When asked what services, Kappy said @lleung @storagemojo standard issue stuff. Snaps, replication, deep VMware […]

IOPS is not the key number

July 2, 2014

Americans love round numbers. 600HP. 200MPH. $1,000,000,000. 15% capital gains tax rate. 10Gb/s. 6TB drive. 1,000,000 IOPS. $2/GB. Those are brawny, manly numbers that red-blooded Americans can relate to. Not fussy little decimals, sliding further into irrelevancy with each succeeding digit. We’re even less fond of ratios. A 600HP car. What’s the power to weight […]
