Many analyst/consulting firms have dubbed storage automation as the "next big thing" in storage management. For instance, the Enterprise Storage Group ("storage process automation"), the Yankee Group ("storage automation"), and Strategic Research ("storage operations management") have all weighed in with comprehensive reports on the subject.
Business continuity and disaster recovery have taken on a very high profile, requiring more and more organizations to extend their storage over long distances using a wide area network (WAN).
The promise of iSCSI for early adopters is affordable storage consolidation solutions for server environments where simplicity, flexibility, and price/performance are critical IT decision factors.
RAID systems were developed more than a decade ago to solve the common problem of failed disk drives causing applications to fail and end users to lose access to their data.
Two years ago, it was defense-in-depth. Last year, it was cyber terrorism. Now a new topic is raising quite a few eyebrows in IT organizations: storage security. Until recently, they were independent issues.
When InfoStor polled its readers about their business continuity preparedness, we were somewhat surprised to find that the majority of respondents said they had a plan in place and tested it regularly (i.e., at least once a year).
Snia On Storage
Data storage and networking technologies are changing. Some of those changes could increase your risks of data loss, damage, or unauthorized disclosure of sensitive data.
It's been three years coming, but there are signs that iSCSI may be ready for end-user adoption.
News Analysis Trends
Analysts view EMC's acquisition of Legato, which is expected to be finalized in October, as a win-win for both companies, and most analysts see it as a positive deal for end users—with a few caveats.
Earlier this summer, Microsoft announced the availability of its iSCSI software initiator package, which includes a software driver and initiator service.
At its annual CA World conference in Las Vegas last month, Computer Associates outlined its vision of on-demand computing and described some of the near-term steps the company plans to take toward that goal.
You would have had to be living under a rock for the past few months to have missed all the vendor noise about SEC 17a, HIPAA, and Sarbanes-Oxley. In fact, many storage vendors have made these new regulations a central focus of their marketing efforts.
Citing limitations to in-band virtualization, MonoSphere claims its out-of-band approach to storage virtualization does not cause single points of failure or use host CPU cycles, and can talk to storage area networks (SANs), network-attached storage (NAS), and direct-attached storage (DAS)—a key differentiator from its competitors, according to analysts.
With the completion of its acquisition of Precise Software earlier this summer and the release of the first products from its acquisition of Jareva Technologies (see "Veritas expands beyond storage," InfoStor, July 2003, p. 8), Veritas is pushing beyond its storage-centric roots and into more direct competition with Computer Associates, IBM/ Tivoli, and EMC.
Reader I O
Let me first clarify the claim that I made in that column (see "Is disk-based backup all that it's cracked up to be?", July 2003, p. 24). I was addressing a reader who wanted to know if staging his backups to disk would improve performance over sending data directly to tape.
Long known for its low cost, heterogeneous file sharing, and simple installation—among other benefits—network-attached storage (NAS) is difficult to manage when scaling beyond the first few appliances.
You may not think iSCSI needs to be saved, what with the market's renewed attention on the IP-based storage I/O alternative to parallel SCSI, Fibre Channel, and Serial ATA. Yet we've been here before, haven't we?
