Understanding the accumulation of data
The other day, I bought 6 TB of storage for under $300. This statement alone is startling to folks like me who have been following the storage and hard disk drive industry. Searching for a faster alternative led me to crack open the case and experiment with the drive inside.
As techies moan about the lack of upgrade options presented by a soldered in SSD, they miss the bigger industry picture. For too long, computers have been held back by traditional SCSI and ATA controllers. These are both a performance bottleneck and an impediment to innovation. A shift to an integrated PCI storage model makes much sense tactically and strategically for Apple, and I expect that these rumors are true. Furthermore, this move will put even more stress on Windows PC makers. Once again, Apple is outmaneuvering the competition.
The VMware ESX hardware compatibility list is awesome but it’s kind of hard to wade through. It’s super-detailed, but difficult to navigate if one is browsing for compatible hardware. Although SATA and especially PATA aren’t exactly mainstream in enterprise datacenters, they’re the most-likely storage attachment for labs and tinkerers like me.
As I considered the possibilities of the new Apple/Intel interconnect technology known as Light Peak, an odd parallel with 10 Gb Ethernet popped into my head. Much of the confusion around Light Peak revolves around connectors, power conduction, and backward-compatibility. Then, like the Grinch, I thought of something I hadn’t before: Why use optical at all? 10 GBASE-T does just fine over twisted pair, and short interconnect distances would reduce power draw to reasonable levels. What if Light Peak was electrical rather than optical?
It’s hard to stand out in the world of external storage devices, and doubly-hard to compete with the hard disk drive makers themselves. This hasn’t stopped folks like Iomega, Verbatim, and LaCie from trying to impress customers with flashy cases, software bundles, and clever functionality. But clever new twist on the external hard drive concept just rolled into the Pack Rat lair: The ioSafe SoloPRO is fireproof and waterproof. Cool!
More information about the unconventional SSD used in Apple’s new MacBook Air. As I discussed in my previous coverage of this new flash form factor, it resembles a PCI Express Mini Card but is much smaller. Toshiba has now proved my speculation that the device uses SATA signals rather than the PCI Express lane used by the similar AirPort card. We also know that the lauded performance of the device is due to its chips and controller rather than skipping SATA in favor of PCIe as some had speculated.
How fast is a hard disk drive? How about the various flavors of SATA and Fibre Channel? Check out this handy Pack Rat infographic to answer the question, “how fast is it?”
It is tempting to think of storage as a game of hard disk drives, and consider only The Rule of Spindles. But RAM cache can compensate for the mechanical limitations of hard disk drives, and Moore’s Law continues to allow for ever-greater RAM-based storage, including cache, DRAM, and flash. But storage does not exist in a vacuum. All that data must go somewhere, and this is the job of the I/O channel.
Apple updated the ultra-slim don’t-call-it-a-netbook MacBook Air this week. Along with a wimpy out-of-date CPU, the new Air features all-SSD storage of an entirely new and apparently proprietary type. Let’s take a look and see what we can see.
With Apple almost certain to introduce a new MacBook Air, questions have turned to the specifics of the hardware to be used. A leaked pre-production photo features an odd memory configuration (not to mention four batteries), a device I immediately recognized as an SSD-on-a-stick. With this high-profile introduction of a new SSD stick form, I thought it was time to cover these unconventional new storage formats.
This week, two blog readers let me know what Google Chrome was warning them of malware on my blog. I dived in and discovered that, indeed, a nasty, obfuscated JavaScript attack had made its way into my site. Although I was disappointed by the lack of clarity about how to fix it, I believe I was able to remove it last night.
Although Clear clearly wants buyers to sign up for monthly service, they also have “secret” on-demand 2-hour, daily, and weekly plans. Here’s how to get online cheap!
HP stumbled mightily in 2011, and it had nothing to do with product or people. Even sales remained strong, though the PC business is changing. HP’s mighty stumble was a crisis of confidence due to a chain of shenanigans at the very top. This culminated with the short reign of Léo Apotheker, leaving HP to reassure the market of its strategy.
For a massive IT company, Dell sure doesn’t get the kind of respect given their competitors. Time and again, I’ll hear the sneers about Dell being little more than a “box shifter” who doesn’t “get” real enterprise IT needs. After a series of acquisitions in storage and networking, Dell is trying to stake a claim as a serious competitor to HP, IBM, Oracle, and the like. But why should anyone take Dell seriously, especially in enterprise storage?
Any time OS X corrects your spelling or (more likely) inserts appropriate accent marks, Dictate loses its mind and can no longer correctly enter some random letter. There are two ways to fix this problem (apart from just restarting Dictate all the time).
Moving cold virtual machine images from system to system, or even across great distances, is one of the main selling points of server virtualization. But it becomes much more difficult to manage movement of virtual machines that are still running, especially outside cluster or across WAN links. When talking about virtual machine mobility, it is important to consider what is being moved, the state it is in, and where it is going.
The difference between American and European mobile phone providers are vast, and the modern traveler is likely to run afoul if they are unprepared, running up a surprisingly large bill! Here’s a rundown of my standard techniques to prepare my American mobile phone for travel abroad.
The CompactFlash Association announced a new media card format last month, and now Sony and Nikon have introduced the first media and digital cameras, respectively. But what exactly is an XQD memory card? Read on for the details.
What elements remain unresolved to make FCoE truly world-class? What should the vendors be prioritizing?
Although they are ridiculously inefficient, incandescent lightbulbs seem to have a huge number of fans. Despite the romance of the glowing filament, many governments are moving to ban the use of incandescent light bulbs in many applications. Here in the United States, the federal government intends to encourage the use of more efficient light bulbs but there is no outright ban.
