Thoughts On A Dell Acquisition Of Compellent

The news came out this morning that Dell is in exclusive talks to acquire network storage specialist Compellent for just under $900 million. I will leave it to the real reporters to track the ups and downs of the story; what piques my interest is the value Dell gets from Compellent’s technology and the challenge it poses to the data storage industry.

Data Dedupe comes to ZFS

It’s official… Data deduplication has been added to ZFS (read the link if you’re new to data deduplication). Hats off to Jeff Bonwick and Bill Moore who did a ton of the work in addition to Mark Maybee, Matt Ahrens, Adam Leventhal, George Wilson and the entire ZFS team.  The implementation is a synchronous block-level [...]

Can and when will SSDs + SATA replace FC/SAS?

Simon Seagrave (http://www.techhead.co.uk/) asked, “How long do you think it’ll be before SSD will overtake SCSI as primary tier 1 SAN storage? Giving a new SSD and SATA tiered mix.”
Short answer: Yes, it will be SSDs + SAS and within 2 years.
The real quesion is when 15K RPM highspeed drives will be replaced with SSDs [...]

Review: Sun Storage 7000 Unified Storage System – Part III

In this post, I’ll be discussing some of the analytics features of the 7000 arrays and how the rich data it offers provides customers with added insight into getting the best performance for their money.

LSI Picks Up ONStor

Just five days after HP announced it would acquire IBRIX, another scale-out NAS provider has been purchased. LSI announced today that it would acquire ONStor for $25 million in cash. The company sold a range of SAN and NAS storage systems, but was best-known for its Bobcat clustered NAS gateways.

Review: Sun Storage 7000 Unified Storage System – Part II

Traditional storage arrays permit the configuration of multiple disk types within a single array. This can range from solid state disks (SSDs), through to fast fibre channel drives and slower high capacity SATA drives. USS operates a slightly different model – all drives in the USS array are high capacity SATA. SSD drives are then used to ameliorate performance on read and write activity in combination with the ZFS file system, by using the SSDs for read caching and write logging.

How to Resize ZFS

If you’ve been experimenting with ZFS, as we have, you’ve been struck by some of its limitations in terms of flexibility, but there is one way to expand a zpool, as demonstrated by Harry D in a two-part blog post.

Interested in ZFS? Check Out c0t0d0s0!

We in the storage and server fields (not to mention Apple fans) have been watching ZFS with keen interest for a while. It holds great promise as the next-generation UNIX filesystem foundation, and Joerg Moellenkamp over at c0t0d0s0.com has been covering Sun’s open-source ZFS super-filesystem for quite a while.

Don’t Be Blinded by the Flash!

At the moment, Enterprise Flash disks are all being used as faster spindles; as faster replacements to spinning rust. In the same way that I could remove my laptop/pc drive and replace it with a SSD; I can do it in an array at some extortionate price.I know there’s been a fair amount of tweaking to get them into the various arrays but it doesn’t appear to be the proverbial rocket science! So can we have some rocket science now?
