Big data storage: Apache Cassandra 0.7 released

The Apache Cassandra project released version 0.7 of their distributed database server earlier today. Cassandra aims to provide a fully distributed, high-available, scalable database that can store huge amounts of data and process them fast. The project was open sourced by Facebook in 2008, and Cassandra is currently used by some of the largest sites on the internet such as Facebook and Twitter, with at least one installation storing over 100TB of data.

Intel has been talking to several news outlets about their Light Peak technology at CES. While we all knew Intel was going to push this standard in favor of USB 3.0, this is the first time they have mentioned actual finished implementations. Previous estimates said the technology was likely to be ready sometime during 2012; but there is a bit of fine print in this announcement.

Battle over ZFS heats up

NetApp has asked one of their competitors, Coraid, to halt the sales of their EtherDrive Z-Series NAS appliances. The reason? Coraid is using the ZFS file system. Coraid has sent a letter to their customers announcing a temporary sales stop. The Z-Series NAS was announced in May, so NetApp didn’t waste any time in sending their legal threats.

EMC reminds us not to rely too much on cloud services yet

Cloud storage might be a good idea for some use cases, but that doesn’t mean any service provider is a good choice. EMC announced last week that its Atmos Online service was no longer offering any SLA’s and is no longer supported for production usage:

We will no longer be offering paid subscription or support for Atmos Online services.  Any existing production accounts will not be billed either for past or future usage.   We will also no longer provide any SLA or other availability commitment.  As a result, we strongly encourage that you migrate any critical data or production workloads currently served via Atmos Online to one of our partners offering Atmos based services.

Seagate debuts 3TB external drive

Seagate is the first vendor to offer 3TB hard drives. This first drive is only available as an external USB 2.0 drive for now; for $249.99 you can buy a Seagate FreeAgent GoFlex Desk External Drive (try saying that a couple of times in a row!). The drive is currently on back order, but should be available soon. The $249.99 package includes a USB 2.0 host interface, but can be upgraded by switching the base of the unit. Other interface options available are USB 3.0 and FireWire 800.

Hot-swap SATA to USB 3.0 dock from ThermalTake

I’ve seen a couple of UB 3.0 drive docks announced over the last couple of months, but this new model from ThermalTake stood out in my mailbox. The BlacX 5G supports both 3.5 inch and 2.5 inch SATA drives; instead of traditional external drive enclosures where you have to open a case to insert the disk, this unit allows you to insert a drive without any other steps.

Standard for faster SD cards announced

The SD Association has announced a faster interface specification for the ever-popular SD card format. The new UHS (Ultra High Speed) bus can achieve speeds of up to 104 MB/s; that’s four times the speed of the previous maximum. Cards and readers conforming to the new spec are backwards-compatible with previous generations, and can be recognized by a new symbol that includes a “1”, which stands for “UHS Speed Class 1”.
