Virtualization decouples physical infrastructure from logical resources (photo by Roy Smith)

Virtualization of IT systems decouples physical infrastructure from logical resources, hiding complexity and enabling new capabilities. However, not all potential benefits of virtualization have meaningful value outside IT circles: Too many of our discussions revolve around the very complexity that virtualization technology should be hiding! True business value is derived from transformed virtual resources in the next-generation data center, not the incremental capacity gains of virtual servers. But how will we get there, and what will this future look like?

You can never be totally secure, but basic precautions like this simple cable lock for laptops can help

This is part of an ongoing series of longer articles I am posting on Sundays.

In this digital age, it is easy to overlook the critical element of physical security. Put simply, it is often far more efficient to steal or gain access to a physical object like a laptop or flash drive than to break into a computer system. And despite the sanitary and controlled environments many mobile employees often travel in, risks to personal safety are real. Therefore, it is sensible to consider the physical security needs of the road warrior. Continue Reading »

The tech industry has been buzzing about solid state drives (SSDs) again lately, but many questions remain. Even after many major vendors (Apple, EMC, and Dell to name a few) have introduced NAND flash-based disk into their core products, it is unclear whether non-disk storage will fly or flop. I’m betting it will find a nice niche, but that traditional spinning disks are here for a good long time. Continue Reading »

This is not a political blog, and this will not be a political post. But there is something to be learned about marketing from the way that political campaigns market their candidates, and this is a lesson for all time.

Watching the polls on FiveThirtyEight, the push and pull between moonbats and wingnuts on Electicker, and the strongly opposed views expressed in the letters to the editor section of my local paper, I began to ask myself how two obviously different candidates could be so close in the polls. Are Americans really divided almost equally between these two men, their running mates, and their platforms? How can so many people want the old senator and the unqualified governor? How can so many want the pairing of un-American and crazy senators?

I began comparing them to Coke and Pepsi, McDonald’s and Burger King, and I realized I was right. These candidates are marketed with extreme precision to maximize their appeal to the widest set of American voters. I imagine that their intrinsic qualities could eliminate them from consideration for some and cement their appeal to others, but the bulk of the electorate is swinging on the messaging. And this simple fact explains why Obama/Biden is now leading against McCain/Palin. Continue Reading »

Balancing work and life has never been easy, and this is especially true for the knowledge worker. It isn’t an exaggeration to say that we keep our jobs in our heads at all times, and modern electronics like the BlackBerry and laptop tend to keep it at our fingers as well. When our jobs require us to travel, work can effectively separate us entirely from our lives for days or weeks at a time. Road warriors must consciously try to focus on life, even as work pulls their attention away. Continue Reading »

There has been a lot of discussion in the storage industry about Fibre Channel over Ethernet (FCoE), making it the toast of Storage Networking World, but this technology remains relatively unknown to end users. Like so many storage protocols before it, the $10,000 question is whether FCoE will take off like iSCSI or fizzle as a niche product like FCIP, DAFS, and so many others.

If it does succeed, another critical question is what this means for iSCSI, Fibre Channel, InfiniBand, and to a lesser extent AoE, expanded SAS, and other options for SAN storage. The enterprise data center is poised for a complete change in server connectivity, with 10 Gb Ethernet converged network adapters (CNAs) and new core switches carrying both network and storage traffic, and this holds promise, especially in virtualized environments. But CNAs do not equal FCoE, and iSCSI, conventional Fibre Channel, and other protocols are roaring ahead. What impact will FCoE really have?

Homes now need data storage as well as closets...

This is part of an ongoing series of longer articles I will be posting every Sunday as part of an experiment in offering more in-depth content.

Along with my professional focus on enterprise storage systems, I’m enamored of home networking, and recently passed the three terabyte mark at home! This got me thinking about where home storage is heading.

As you can see in the photo, my office closet is overflowing with computer equipment (and one sweet guitar), but my data storage is much better organized. I have a hacked Linksys NSLU2 with 500 GB as a file server, a 500 GB PC backup disk, a 160 GB Time Machine disk, 1 TB of TiVo storage, and the rest. But wouldn’t it be nice if this could all be combined into some kind of super home server?

Many storage challenges focus on correlating high-level uses of data (such as applications) with the nuts and bolts of storage infrastructure. These discussions often revolve around the conflict between data management, which demands an ever-smaller unit of management, and storage management, which benefits most from consolidation. Developing data management capability that is both granular enough for applications and scalable enough for storage is one key to the future of storage.

Although many discussions in the storage industry focus on the relative merits of one protocol or another, the conversation occasionally turns to the core issue at hand: We continue to patch together a system based on outdated concepts. Most storage protocols continue to mimic direct attached storage, and most of our so-called networks act as point to point channels. An ultra-modern virtualized storage infrastructure with all the latest bells and whistles still holds the concepts of block and file at its core. Whenever the storage industry has tried to bring about real storage management they have been stymied by a lack of context for data.

No amount of virtualization, and no new protocol, will fix this. Put simply, we need a storage revolution. Continue Reading »

I am not the typical enterprise storage user. In fact, I am not an enterprise storage user at all – I am a consultant focused for over a decade on assisting enterprises with their storage architecture and strategy, working with businesses of all sizes. My background is both a blessing and a curse – I have seen far more enterprise storage environments in much more detail than most people, but I am unable to truly empathize with my corporate storage compatriots since it’s not really my gear and data that I am working with.

Based on this experience, what does the future hold? Where is enterprise storage heading? Read on for my thoughts.
