IBM recently announced iBoot, a new storage technology that enters the ongoing struggle between distributed and centralized storage strategies. In essence, iBoot, which IBM's Haifa Research Laboratory developed in Haifa, Israel, brings to desktop computing many of the same concepts that have long informed mainframe computing (see URL below). Instead of storing information locally on a hard disk, individual users designate storage space on a larger disk on the network. The disk appears to be local, but it isn't.
Fundamentally, the iBoot technology lets desktop computers operate without a local hard disk. Instead, the computer uses the Internet SCSI (iSCSI) to connect to a hard disk over the network and can boot up Windows XP, Windows 2000, or the Linux OS by using a remote machine (see first URL below). IBM researchers say that iBoot is the first technology to support the remote booting of any Windows OS. Although technologies such as Etherboot, an open source software (OSS) application (see second URL below), and Intel's Preboot Execution Environment (PXE—see third URL below) have supported remote boot for Linux, IBM researchers claim those approaches aren't transparent to the end user. Moreover, Etherboot and PXE require that the entire booted OS be sent to the diskless PC and retained in memory. Users can't make any permanent changes to the OS kernel.
With Etherboot and PXE, a client computer obtains the location of a target computer, then, by using the Trivial FTP (TFTP), downloads a root file system and OS kernel and executes the OS kernel. IBM iBoot uses a different approach. For iBoot, however, IBM researchers have created a small-option ROM image that contains iSCSI client code, a TCP/IP stack, and BIOS interrupt code. When a user turns the machine on, the BIOS disk I/O interrupt uses the iBoot code to communicate directly with a remote drive. With this approach, users can make and retain permanent changes to the OS kernel. Although storage can then take place centrally, each desktop still retains its customized computing functionality.
You can easily envision the advantages of consolidated desktop storage. Hard disk crashes have been a nightmare for a generation of users and systems administrators. One centralized storage space for desktop computing would make backup and restore operations much easier to manage.
Desktop storage is an underutilized resource in many enterprises. As hard disk capacities continue to grow, each desktop contains more and more unused space. A standard desktop computer configuration in many enterprises now includes a hard disk with a minimum of 20GB. Disk drives with 80GB to 120GB hard disks are common. Many users use less than 25 percent of that capacity, and they'd use even less if they had an incentive to erase data they no longer need. However, as rich media use becomes more commonplace, users will need more storage to handle their audio and video files. Centralized hard disks would make it much easier for storage administrators to control that growth.
Moreover, desktop storage centralization can reduce the cost of storage upgrades—every desktop would no longer need an upgrade. In the long run, iBoot could impact the design of many classes of computers, from servers to handhelds. IBM researchers have suggested that in the future, computers might come with very small hard disks designed to hold temporary files or small amounts of information (or in the case of servers, no disks at all).
Currently, iBoot is a technology, not a product, and iSCSI network cards are only now being introduced into the market. Although most pundits think that iSCSI will soon catch on as a significant network storage protocol, its rate of acceptance is unknown. Nevertheless, iBoot is another technology that will require storage administrators to clearly think through organizational and end-user storage needs. Increased storage capacity isn't the issue; whether that capacity is centralized or distributed is.

IBM and Hitachi have announced a definitive agreement for the companies to transfer their Hard Disk Drive (HDD) assets to a new standalone company. The transfer is one part of a business alliance the companies announced in April. The companies hope the transfer of assets will help them be more competitive in their core businesses. According to industry insiders, IBM's HDD business has lost money in recent years.
Hitachi has agreed to purchase the majority of IBM's HDD-related assets for $2.05 billion, including the transfer of IBM's HDD-related intellectual property portfolio. Hitachi will initially own 70 percent of the new company and will make a series of fixed payments to IBM before assuming full ownership in 3 years.
The new company will be based in San Jose, California, and will comprise about 18,000 employees from IBM and 6000 employees from Hitachi. An independent team of executives drawn from Hitachi and IBM's existing HDD operations will manage the new company.
Hitachi estimates the new company will make about $5 billion in sales in fiscal year 2003 and $7 billion in sales by 2006. Both IBM and Hitachi will use the new company as their HDD supplier. The companies expect the agreement to close by the end of the year.
Imation, Quantum, and Maxell announced that they have settled all legal claims between the companies involving DLTtape media products. (The DLT technology competes with Linear Tape-Open—LTO—and AIT.) Last October, Imation filed a federal antitrust lawsuit against Quantum, accusing the company of thwarting Imation's efforts to produce DLT-compatible cartridges. In December, Imation amended the complaint to add Maxell. Quantum filed a counterclaim in California state court, stating that Imation violated Quantum's trade secrets and seeking an injunction to prevent Imation from selling DLT products. Maxell also filed a counterclaim, alleging that Imation engaged in false advertising. As part of the settlement, all suits will be dismissed.
Under terms of the settlement, Quantum will pay Imation $5 million over 18 months and enter into a multiyear business and supply agreement. Further details of the settlement weren't released. Maxwell will also pay Imation an undisclosed sum. Imation will now be able to sell certified DLT and SuperDLT products.

Q. How can I use Windows XP to erase files from a CD-RW disk?
A. You can delete files from a CD-RW disk by performing the following steps:
- Place the CD-RW disk in your CD writer.
- Start My Computer (go to Start and click My Computer).
- Right-click the CD-RW drive icon and select Open from the context menu.
- Select "Erase this CD-RW" from the CD Writing Tasks bar in the left-hand pane of Windows Explorer to start the CD Writing Wizard.
- Click Next to begin the wizard's erase process. A progress dialog box will display and confirm that XP has erased the files from your CD-RW.
