Back From the Pile: Interesting Links, October 17, 2010

A while back, I started a series called “back from the pile” featuring interesting links from the week. Bonus points if you recognize that title reference! This week’s highlights included lots about NFSv4 and IBM’s new Storwize V7000. Some great networking content, too!

Overland Snaps Up MaxiScale to Scale Up Snap

Overland's SnapServer will soon scale out to hundreds of nodes, thanks to MaxiScale's technology

Overland Storage is showing intriguing signs of life. Once relegated to OEM tape library duty, Overland received an injection of cash and (more importantly) talent this year. Now the company is stepping up the technology behind their SnapServer NAS array by acquiring scale-out file storage company, MaxiScale. They intend to bring the scalable capacity and performance normally associated with enterprise and high-performance computing systems to the mass market.

Huawei Symantec Enters The United States Storage and Security Market

Huawei Symantec recently introduced their SAN, NAS, and security offerings for the United States market

Surprise! Huawei Symantec has arrived in the United States, ready to take on the midrange storage and network security market with a line of devices that have proven their worth in the international market for three years. I sat down with the company’s management at Storage Networking World and quizzed them on their plans and aspirations for growth.

IBM’s Storwize V7000: 100% SVC; 0% Storwize

Green = SVC 5; Pink = SVC 6.1. No Storwize.

Today, IBM alerted the world that they had not fallen asleep at the wheel by kicking out an awfully-impressive midrange storage array, the Storwize V7000. This seems like an excellent device, filled with proven engineering borrowed from the successful SAN Volume Controller (SVC) line of storage virtualization products. But closer examination (and IBM’s own Tony Pearson) reveal that it contains exactly nothing from their Storwize acquisition apart from the name.

The Four Horsemen of Storage System Performance: Never Enough Cache

Write-Through Cache

Perhaps the previous discussion of spindles left you exhausted, imagining a spindly-legged centipede of a storage system, trying and failing to run on stilts. The Rule of Spindles would be the end of the story were it not for the second horseman: Cache. He stands in front of the spindles, quickly dispatching requests using solid state memory rather than spinning disks. Cache also acts as a buffer, allowing writes to queue up without forcing the requesters to wait in line.

SMB Arrays: Drive Carriers Or Not?

Many small storage arrays, like this Iomega ix4, use carriers to hold hard disk drives securely

One reason I decided to work with the folks at DCIG to collect data for their Small Business Storage Array Buyers’ Guide was to learn more about the various products in the space. One difference I noted in these small arrays, which usually hold 4 to 8 drives, is their use of hard disk drive carriers or sleds. There are pros and cons to both approaches, but I was pleased to see that all arrays so far include everything needed to install a drive.

How To Make TimThumb Play Nicely With TanTan’s WordPress S3 Plugin

Just a random photo to demonstrate that TimThumb is working properly with Amazon S3

I’m loving the Woo theme for this blog, and especially love that they integrated the cool TimThumb script to automatically resize thumbnails for the main page. But everything stopped working when I added TanTan’s Wordpress-S3 plugin to store my images on Amazon’s servers. Luckily, I found a fix!

Is NFS v3 Really That Bad?

Do we really need parallel NFS?

Did some pNFS proponent slip a love potion into the coffee at EMC? Suddenly it’s pNFS time at the company known for its reluctance to embrace file sharing and filesystems in general. The purple prose is flying, with Chad Sakac declaring himself “a big fan of the application of NFS” and Chuck Hollis extolling the “inherent simplicity and ease-of-management of NFS.” The NetApp guys must be amused by the bear hug from Hopkinton, but many are seeing deja-vu all over again.

Hitachi GST Joins WD On The “Advanced Format” Hard Disk Drive Bandwagon

Advanced Format is on the rise, with Western Digital and now Hitachi GST supporting the 4K drive addressing method

Another limit is being pushed in computers: The 32-bit LBA addressing mode. Hard disk drives have simply become too big for the 2.1 TB allowed by 32-bit LBA and 512 K sectors. Western Digital was first to answer this challenge with “Advanced Format”, and Seagate took an alternate 48-bit LBA route. Now Hitachi GST introduced an Advanced Format drive of their own. Will the industry ever adopt 48-bit LBA?

Review: DroboPro FS is Data Robotics SMB NAS

Data Robotics is back with the DroboPro FS 8-drive NAS for small business

Data Robotics today launched their sixth product, the business-oriented DroboPro FS file server. Combining the 8-drive chassis from the direct-attached DroboPro with the Linux-based file server engine fro the Drobo FS, the DroboPro FS (or “Pro FS” for short) gives small businesses and remote offices a simple networked location for their shared files. Although it is a bit more expensive than some of the competition, the Pro FS promises to be as easy to set up, use, and grow as previous devices from Data Robotics.
