- Five new developments in storage infrastructure solutions
- First there was Ethernet. Then, there was IP over Ethernet. Next came the mixed use of Ethernet, IP, and the SCSI command set iSCSI to simplify storage and to bring down the cost and complexity of storage. Today, iSCSI and Fibre Channel are fighting it out in all but the...

- First 8Gbps Fibre Channel products are out
- It appears that the first 8Gbps Fibre Channel storage networking products are out, as reported by The Register. Still, the sentiment is that it will be unlikely that this new technology will do much to stem the drift to iSCSI over 10Gbps Ethernet, although it might perhaps slow it...

- How do I... Install, configure, and use Microsoft's iSCSI initiator?
- Auditing?Since Windows sees iSCSI drives as any other volume does that mean you can enable auditing on them? We need to be able to audit file access which rules out most NAS. If we can enable auditing on iSCSI drives that would be a perfect solution!Auditing!If the volume...

- Shared block-level storage continues to become more accessible
- I considered entitling this post "Is storage becoming commoditized?" but the technical definition of "commodity" doesn't quite fit the bill. My question is this: Is the market for shared block-level storage continuing to become more accessible to a wider variety of customer? Personally, I think it is, and...

- ATA over Ethernet: Worth considering?
- When it comes to shared block storage, your choices areever-expanding. Even better, they are expanding in the downward direction whenit comes to price. As prices come down, the technical nature of each solutionchanges drastically and, although the price might be right, the solution maynot fit the bill. I've written quite...
