1983 - Purchased a Compaq Portable. Running Lotus 123, DBase and WordPerfect. It had a 10meg hard drive. Eventually I added a 20meg PlusCard. I thought I would never run out of room.
The IBM 3270 is a class of block oriented computer terminal (sometimes called display devices) made by IBM originally introduced in 1971[1] normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text colour on the original models, these terminals are informally known as green screen terminals. Unlike a character-oriented terminal, the 3270 minimizes the number of I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable.
Although IBM no longer manufactures 3270 terminals, the IBM 3270 protocol is still commonly used via terminal emulation to access some mainframe-based applications. Accordingly, such applications are sometimes referred to asgreen screen applications. Use of 3270 is slowly diminishing over time as more and more mainframe applications acquire Web interfaces, but some web applications use the technique of "screen scraping" to capture old screens and transfer the data to modern front-ends.
1985 - Purchased my first Toshiba Laptop. A Toshiba T1000 Ran DOS 2.11 on a Ram Disk. Had a 640 kb ram disk as well. 80 columns by 20 rows.
The Personal System/2 or PS/2 was IBM's third generation of personal computers released in 1987. The PS/2 line was created by IBM in an attempt to recapture control of the PC market by introducing an advanced yet proprietary architecture. IBM's considerable market presence plus the reliability of the PS/2 ensured that the systems would sell in relatively large numbers, especially to large businesses. However the other major manufacturers balked at IBM's licensing terms to develop and sell compatible hardware, particularly as the demanded royalties were on a per machine basis. Also the evolving Wintel architecture was seeing a period of dramatic reductions in price, and so these developments prevented the PS/2 from returning control of the PC market to IBM
Sage Technology designed the Sage II around one of the fastest and most powerful chip available at the time, the Motorola MC68000, which was designed, among other things, for the implementation of high-level languages.
The Sage II, didn't look awesome. It was physically smaller than an Apple II, but packed a true 16 bits CPU and 512 KB of RAM. Only 128 KB were left free for the user, the remaining 384 KB being used as a RAM disc.
The Sage II used the UCSD P-System operating system. P-System means P-Code, an early universal intermediate code concept for programming languages, the same idea that Java is now based upon. Sage had even modified the P-System so that the system was truly multi-user. A special version of CP/M called CP/M 68K could also run on the Sage II.
One or two Mitsubishi 5.25 inch floppy drives were used to store programs and data. Each one could store up to 800 Kb per disk in the native Sage format. They were fully software configurable and had preset formats for IBM, Xerox, Rainbow and other systems. The only problem is that the Sage II didn't provide any hard disk management. This is will only be possible with the Sage IV model (10 to 40 MB hard disks).
Macintosh SE/30
Recently voted the 'best ever Macintosh' by a Macworld panel, the Macintosh SE/30, which cost $4,900 at launch in 1989, had a 16MHz Motorola 68030 processor, 1MB of RAM (expandable for the first time beyond 4MB), a hard drive (40MB or 80MB), a high-capacity (1.4MB) floppy drive and an expansion slot (PDS). It retained the original Mac's 9in. 512-by-342-pixel black-and-white screen.
The IBM System/36 (often abbreviated as S/36) was a minicomputer marketed by IBM from 1983 to 2000. It was a multi-user, multi-tasking successor to the System/34. Like the System/34 and the older System/32, the System/36 was primarily programmed in the RPG II language. One of the machine's more interesting optional features was an off-line storage mechanism (on the 5360 model) that utilized "magazines" – boxes of 8-inch floppies that the machine could load and eject in a nonsequential fashion. The System/36 also had many mainframe features such as programmable job queues and scheduling priority levels.
Novell, Inc. /noʊˈvɛl/ is an American multinational software and services company headquartered in Provo, Utah. It has been instrumental in making the Utah Valley a focus for technology and software development. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide. Today, a primary focus of the company is on developing software for enterprise clients. It is a wholly owned subsidiary of The Attachmate Group.
System/390 ES/9000 Processor characteristics
The following is the text of an IBM U.S. Marketing & Services press release distributed on September 5, 1990.
The IBM Enterprise System/9000 (ES/9000) family of 18 processors announced today for System/390 range from intermediate computers for office environments to the most powerful mainframe systems the company has ever offered.
IBM Board Chairman Thomas J. Watson Jr. called the event the most important product announcement in the company's history.
The new general-purpose processors offer highly attractive price/performance and internal performance growth of more than 100-fold from the entry model to the high-performance top of the line. ES/9000 has the industry's broadest single-family range of performance and upgrade options.
| The SUN Enterprise 4000 consists of a chassis that support up to eight system boards, four power supplies and a maximum of four disk boards. The Enterprise 4000 requires a minimum of one I/O board and accepts a maximum of seven CPU boards. All components are hot-swappable. The SUN Enterprise 4000 can be installed as a desktop system or rack-mounted in an Enterprise cabinet. | ||
| Sun E10000 Server Enterprise Server Because the Sun Enterpires 10000 ( E10000 ) support for up to 64 CPUs, 64 GB of shared memory, and more than 100 TB of storage it is perfect for large-scale, mission-critical applications including high-volume OLTP, server consolidation, data warehousing, decision support, and high performance computing. The Sun Enterprise 10000 also offers exceptionally fast, uniform memory access with near linear scalability--up to 12.8 GBps data bandwidth with less than 500 ns constant latency. |
Sun | Sun Fire 6800 Server
Introduced in April of 2001 as the replacement for the Enterprise 6500 server, the Sun Fire 6800 server is a 24-processor machine that used UltraSPARC III CPUs (750MHz), UltraSPARC III Cu (copper based) CPUs (900MHz, 1050MHz or 1200MHz), UltraSPARC IV CPUs (1050MHz, 1200MHz, or 1350MHz), and UltraSPARC IV+ (1.5GHz or 1.8GHz) CPUs.
Maximum memory for the Sun Fire 6800 is 384 GB using 1GB DIMMs.
The Sun Fire 6800 incorporated D240 media trays to provide disk, tape, and DVD-ROM drives, the drive capacity of each D240 media tray being 2 ea. 18.2, 36.4, 73.4, or 146.8 GB SCSI disk drives.
The Sun Fire 6800 comes in its own 75” data center cabinet, which had additional room for disk arrays and D240 media trays.
Oracle Real Application Clusters
Oracle Real Application Clusters (RAC) is a software component you can add to a high-availability solution that enables users on multiple machines to access a single database with increased performance. RAC comprises two or more Oracle database instances running on two or more clustered machines and accessing a shared storage device via cluster technology. To support this architecture, the machines that host the database instances are linked by a high-speed interconnect to form the cluster. The interconnect is a physical network used as a means of communication between the nodes of the cluster. Cluster functionality is provided by the operating system or compatible third party clustering software.
vSphere 5.1
VMware, which is owned by EMC, said the two companies developed vSphere 5.1 to simplify the setup and management of backups for VMs through a single VMware console.
The new capability, called vSphere Data Protection (VDP), replaces vSphere's Data Recovery function and is included with all editions of vSphere Essentials+ and above.
"Smaller businesses and departments within larger organisations are the primary beneficiaries of this initial release, as well those who are at the outset of their virtualisation journey," said David Vellante, co-founder of The Wikibon Project, a Web 2.0 community for IT professionals.
Like other backup software products, VMware and Avamar were already integrated at the API level, allowing users to purchase Avamar software and manage it through VMware's vStorage API.
