Storage advanced tech quiz

Take our quiz to see just how much you know about advanced storage technologies and issues.

Take our quiz to see just how much you know about advanced storage technologies and issues. Are you a tough nut or merely a wet noodle? At the very least, you'll walk away with knowledge about burgeoning technologies and be better prepared to face 2005.


1. This visionary technology underlies the various capacity-on-demand visions of storage vendors. It entails abstracting storage hardware and software components to deliver the exact type and amount of storage based on an application's needs at that time.
What is it?

2. This next-generation technology provides a full, dual-ported connection intended to support high-availability computing. It will extend drive addressing to as many as 4,032 devices per port, far beyond SCSI's limit of 15. It will operate point-to-point at speeds up to 3 Gbps.
What is it?

3. This is an architecture and specification for data flow between processors and I/O devices that promises greater bandwidth and almost unlimited expandability in tomorrow's computer systems. In the next few years, this technology is expected to gradually replace the existing peripheral component interconnect shared-bus approach used in most of today's personal computers and servers.
What is it?

4. This technology is a storage system in which all the data in an enterprise is backed up whenever any change is made. In effect, it creates an electronic journal of complete storage snapshots -- one storage snapshot for every instant in time that data modification occurs.
What is it?

5. These are capable of running software services that now run on the host or are built into the firmware of the disk array, such as replication, mirroring or volume management.
What is it?

6. The case for this technology began building as storage became increasingly networked. This technology typically is delivered as an appliance that encrypts and decrypts data as it moves in and out of storage.
What is it?

7. These are gaining traction on Wall Street. These products are appliances that speed up the TCP/IP connection between remote NAS storage and the main data center.
What is it?

8. This technology consists of a software layer that masks differences in a heterogeneous environment through a common interface, a common name space and common management.
What is it?

9. This technology allows data to survive even if two drives fail.
What is it?

Hint: RAID-6 is one way to do this, but not the only way.

10. The concept looks at re-engineering and how storage is deployed and managed in easily classified levels that have different characteristics to meet varying application and line of business needs.
