Let’s look at some best practices for using another powerful class: ThreadLocal from java.lang, which is also implemented using WeakReference. As its name suggests, a single instance of ThreadLocal can store different values for each thread independently. Therefore, the value stored i...
I don't read nearly as much as I should. On plane rides I tend to grab a Vince Flynn, James Patterson or David Baldacci, they are usually enough to entertain me on the way there and back. One of the more interesting books I have read in recent years that does not include murderers, spi...
As you may have read in prior installments of this series, businesses whose IT infrastructure resides on-premise can ease the integration of cloud infrastructure into their existing environment by adopting a phased roadmap that provides numerous benefits along the way. The final insta...
The very name is kind of ridiculous, don’t you think? The word “ephemeral” means it can go away. It’s temporary. Fleeting, even. So why would I want to depend on storing something in a medium that can disappear without warning? And why am I forced to buy more of it when all I want is m...
We’re now entering a world where cloud-managed big data is not just a topic of conversation in tech circles but a necessity for companies and service providers alike. Shifting data needs drive technological innovation. The truth is that as data gets bigger, older technology isn’t abl...
Seagate has announced that it reached a milestone of having shipped 2 billion hard disk drives (HDDs), something that is round stores data that keeps growing. As part of their announcement, Seagate has a good info graphics and facts page here going back to 1979 when it was founded as S...
NetApp announced the other day a new all nand flash solid-state devices (SSD) storage system called the EF540 that is available now. The EF540 has something's new and cool, along with some things familiar, tried, true and proven. What is new is that the EF540 is an all nand flash mult...
The growth of Big Data has, in many ways, come as a result of changes in the way we use the Internet. Today’s Internet is as much a repository of data as it is a way for individuals and organizations to connect with others. As this change has taken place, changes have also come to how ...
In part 4 of the storage subsystem, we’ll provide some guidelines for selecting the stripe-size unit for your selected storage solution. Hardware-managed arrays allow stripe unit sizes ranging from 4 KB to more than 1 MB. The ideal stripe unit size maximizes the disk activity without u...
In the spirit of solid state devices (SSD) including DRAM and nand flash, not to mention emerging phase chance memory (PCM) among others that help to boost productivity and cut latency, here are a couple of quick notes and links. Here are a some more pieces to have a quick look at: S...
Leah Schoeb of The Evaluator Group, wrote a nice piece about storage benchmarking that we highly recommend. I won't reiterate her article here, but I would like to simply point out that the specs many vendors throw around don't come with the appropriate caveats. They don't mention blo...
File System Alignment for SSDs There are many techniques and methods that can be used to tune an IT system to improve overall system performance.  SSD caching is widely being used as a low cost, easy to implement method to quickly increase performance with little or no impact on ...
In the first wave of solid-state storage arrays, we saw commodity style SSDs (solid state drives) being added to traditional storage arrays. This solution provided an incremental benefit in performance over spinning hard drives, however the back-end technology in these arrays was deve...
August seems to have been the month for a huge raft of storage-related announcements and I’m still getting to grips with the detail, after being away on holiday for the whole month. As I start to pick out the news and make sense of how it fits into the storage landscape, I thought I’d...
This week has seen announcements from two companies I’ve been interested in and following for some time. Nasuni makes a storage appliance that stores all of a customer’s data in “the cloud”. It’s available either as a physical device (effectively a server running their software) or a...
Perhaps I should have entitled this post “The Cyclical Nature of IT” because the same principles apply. Over time, storage moves back and forth between fully dispersed and fully centralized like a sine wave on an oscilloscope. The Evidence Look at the evidence. In the 1950′s and 196...
It’s been an interesting day of contrasts in the world of storage, one that shows storage is a diverse and wide ranging segment of IT. Tape has been part of the discussion on the twitterverse and despite everyone’s best attempts, is not dead yet. Tape and backup may not be seen as co...
If you were happily running your IT system but needed some additional performance, chances are you turned to some kind of SSD caching solution to improve performance at a lower cost point than adding more servers or storage. You went on what I am calling a “cache diet” (no, not the “cr...
The IT Dog is waggin’ his tail today with this one. I love progress and the SSD revolution is certainly pushing the storage industry forward on many fronts. New products with SSD in every segment of the IT data chain from the server side SSD to SSD raid storage. SSD capabilities has...
Last September, Microsoft released some information about what customers could expect to see in Windows 8, and at the very end of February the Windows 8 beta became available. There’s been some interesting activity on the blogosphere about it (see a good blog from Jason Perlow here). ...
SystemAdmins were generally the early embracers and end users of VMware ESX as they immediately recognized the benefits of virtualization. Having been bogged down with the pains of running physical servers such as downtime for maintenance, patching and upgrades, they were the natural a...
If you are deciding on a new offsite backup solution to replace tapes in a medium-sized organization you have a lot of choices. Right now, many enterprises in the 20- 2000 employee range are choosing cloud backup services to leverage the much talked about scalability and cost savings. ...
This week, a CloudArray user sent us this email, and he gave me permission to share it. CloudArray has been installed in lots of countries, but I think this is the first airborne installation! We love getting product feedback (good and bad) to help us improve the CloudArray user experi...
With 2012 already upon us, the time has come to make resolutions for the New Year. In the world of IT, this means resolving to abandon bad habits, unreliable processes and cumbersome tasks that often get in the way of business priorities. With the emergence of cloud storage as a viable...
Maximizing performance and minimizing footprint are competing priorities and optimizing both can be a challenge. If you ask IT administrators about their goals for storage infrastructure at remote and/or branch office (ROBO) locations, you’ll likely hear that they want to improve appl...
Drew Robb has a good article about what IT industry pundits including vendors, analysts, and advisors loath including comments from myself. In the article Drew asks: What do you really love about storage and what are your pet peeves? One of my comments and perspectives is that I like...
Cloud computing demand will drive new IT spending over the next five years, as public cloud service providers and the adopters of private cloud solutions invest in the supporting infrastructure, according to a recent market study by International Data Corporation (IDC). Therefore, the ...
You may have read that Thailand recently experienced its worst flooding on record and, as the producer for about 70% of global demand for hard disk drives (HDDs), there is now a severe shortage of disk drives for data storage and server-related products. With analysts predicting a halt...
If you are considering cloud storage for storing business data, you may have questions regarding control and security. The truth is that not all cloud storage solutions are created equal, but when you choose an enterprise-class gateway solution to enable on-premise access to cloud stor...
If you are using or thinking about using cloud storage, you are likely familiar with service level agreements (SLAs) from cloud providers that offer guarantees around the availability of your data and sometimes the durability of your data. The numbers associated with the guarantees are...
Return on investment (ROI) of using the cloud has recently become a popular topic of discussion, though not in a way you might expect. An interesting article by JP Morgenthal entitled There is no ROI in cloud computing presents the opinion that cloud services simply have no ROI. A seco...
One use case that I found particularly interesting, is that of UEFA: someone who used to work at EUFA until very recently explained to me that the Union of the European Footbal Associations has built a 100% disk based archive that replaces the tape libraries they were operating before....
Technically here in the northern hemisphere it is still summer, so there is another summer wedding to announce. The other day Hitachi Data Systems (aka HDS) announced that they finally tied the knot buying their Network Attached Storage (NAS) partner BlueArc whom they have been in a O...
With hundreds of thousands of Petabytes to store in the next few years, the benefits of offloading archives or even seldom accessed data from traditional storage are numerous and may even allow companies to extend the life of their existing data storage. While Part I and Part II of th...
This second installment elaborates on how cloud storage can break the storage array life cycle from an economic and deployment perspective, freeing organizations from the cumbersome administration and high costs of traditional storage.
Anyone who purchases storage arrays is familiar with the many advantages modular storage systems and storage area networks offer. However, they may also be familiar with one of the less desirable attributes of storage arrays: the typical 3-yr to 5-yr life cycle that forces decommission...
