1Vision believes the answer to the management problems facing Windows-based file-server and network-attached-storage (NAS) users lies with its distributed file-aggregation software: vNAS Pro/Enterprise. The software is one of several virtualization products under development that specifically address the NAS market.
Seattle-based Advanced Digital Information Corp. (ADIC) is taking a new approach to hierarchical storage management (HSM). Leveraging its existing HSM, tape, and file-system technologies, the company has developed a storage management suite that it says will enable end users to make more-efficient use of their storage area network (SAN) resources.
Two years after launching the Direct Access File System (DAFS) initiative, Network Appliance is rolling out the first DAFS product, which will accelerate performance for IBM DB2, Oracle 8i and 9i, and Sybase database environments running on Network Appliance filers.
Citing limitations inherent in current network-attached storage (NAS) architectures, Scale Eight is developing an alternative NAS technology via its Distributed Storage Software (DSS), which enables large-scale single-image NAS pools that can scale to hundreds of terabytes, according to company claims.
No one would dispute the benefits of doing backup over a storage area network (SAN) versus over a local area network (LAN). Nor would anyone dispute the potential "killer app" benefits of taking the backup server out of the equation with a serverless implementation.
A recent survey of 323 IT managers at sites with more than 1TB of disk capacity, conducted by Peripheral Concepts, reveals a number of interesting conclusions regarding end users' storage priorities and the rate of adoption of storage area networks (SANs) and network-attached storage (NAS).
All things considered, the tape library market had a good year last year, but not as solid as many had anticipated.
With the promise of IP storage comes a new set of security concerns. In an effort to stay one step ahead of the IP adoption curve, storage vendors have already begun taking steps to provide end users with the necessary tools and education to build secure IP storage networks.
Veritas' recent introduction of Windows 2000 storage software products may help Microsoft make inroads into enterprise data centers, a market space that the software giant has traditionally been unable to penetrate.

I need to build a digital archive for scanned images and other content, and I am looking for the most cost-effective solution.
Before users can take advantage of IP storage, a number of technical hurdles need to be cleared.
Storage administrators can optimize backup assets such as tape libraries, servers, and media to deliver substantial savings in both cost and manageability.
This article, the second in a two-part series, examines the pros and cons of using TCP vs. the User Datagram Protocol for SAN extension.

Finalized standards for running block-level data over IP networks are due this year.
With the confluence of Fibre Channel, IP/iSCSI, and InfiniBand, the "one-size-fits-all" rule won't apply in the storage networking arena.
Many point products are available, but end users are demanding integrated, interoperable, end-to-end solutions.
The dominant mantras in the IT community all involve the repetition of total cost of ownership (TCO) and return on investment (ROI).
To avoid a TCO TKO, storage administrators should consolidate resources and choose subsystems with the right management hooks.
Policy management affects all levels of the storage hierarchy, from disk array controllers to high-level storage management software.
The model hasn't lived up to its original promise, but SSPs can still save IT organizations money because of economies of scale, while providing better data protection.
