Promise of storage for SMBs

Be it up-scaled NAS, down-scaled SAN or a mix of the two, the market of choice for storage vendors this year appears to be the small to medium-sized business. Drobo vendor Data Robotics started the ball rolling a couple of weeks back and now RAID specialist Promise has followed suit with two new SmartStor appliances, aimed expressly at SMBs and offering support for a mix of NAS and iSCSI SAN data sharing.

CES: Data Robotics Drobo S

With Microsoft's next generation Home Server dropping support for its storage fabric technology, Data Robotics' Drobo offers an alternative approach to building large amounts of storage using mis-matched disks. Unlike traditional RAID arrays which require all the disks used to be identical in size, Drobo's BeyondRAID storage array allows you to increase the amount of storage in an array each time you add or replace a pair of larger disks.

Why RAID 6 stops working in 2019

Three years ago I warned that RAID 5 would stop working in 2009. Sure enough, no enterprise storage vendor now recommends RAID 5. Now it's RAID 6, which protects against 2 drive failures. But in 2019 even RAID 6 won't protect your data. Here's why.

Commonly used RAID architectures

RAID, which stands for redundant array of independent (or inexpensive) disks, is a method of placing the same data in different locations on multiple hard drives. There are many different types of RAID (called RAID "levels"), and each has its own relative advantages and disadvantages. This article looks at the most commonly used RAID architectures for Oracle databases.

Compaq revs up RAID controller

Compaq Computer has released a higher-speed PCI card that controls RAID (redundant array of independent disks) storage systems, the Houston computer maker said Tuesday. The card supports the new PCI-X input-output standard, which transfers data twice as fast as the top speed of the existing PCI system. The system has battery-powered high-speed cache memory to speed data transfers and protect the data in the event of a power failure. The system costs $1,599, according to Compaq's Web site. --Stephen Shankland, Special to ZDNet News
