Fujitsu Storage Systems: ETERNUS Family

    Good afternoon,

    Today we will move, actually, to the Fujitsu product line ETERNUS DX - the product line of Fujitsu disk arrays. You can immediately notice that in the ETERNUS family of storage systems today there are the following groups:

    DX - disk arrays
    JX - just JBOD (disk shelf)
    LT - tape libraries
    CS - virtual tape libraries and disk libraries

    In the ETERNUS DX group there are arrays of primary, secondary and senior level. The number of bits in the model also indicates the “steepness” of the array. Arrays DX60 / 80/90 - arrays of entry-level
    DX410 / 440 - mid-level
    DX8700 - high-end array of enterprise level.

    In addition, you can often see, for example, the name ETERNUS DX440 S2. Here S2 is the number of generation of the array. This is the second, most recent generation of ETERNUS disk arrays from the number introduced to the European market. It’s just that until 2009 ETERNUS arrays were in principle not supplied to the European / American markets, while being the technological leader in the market of Japan and a number of Asian countries, where Hitachi was and is the only competitor who could argue with Fujitsu. Actually, it is these two vendors that in total occupy more than 50% of the entire cd market in the region. So, in the spring of 2009, Fujitsu management made a strategic decision to bring its own disk systems to the European markets, which were named ETERNUS DX S1. Prior to this order, 20 years of cfd FUJITSU were called ETERNUS,

    In fact, in Russia / CIS / Europe, the introduction of a brand new in the market was launched. And this despite the fact that at this point Fujitsu had more than 40 years of history in its own development and production of its own disk storage systems. In Fujitsu laboratories, more than 1,000 engineers were developing their own disk systems. Actually, this largely explains the fact that a rather large market share has been occupied in Europe for 3 years. ETERNUS is not a startup that emerged “from nothing” as the fruit of the friendly work of several like-minded friends, but the result of many years of work by a huge group of developers in a high-tech company.

    Historically, in the 60s, FUJITSU actively began to manufacture and market its own mainframes, and then disk storage systems were needed. A corporation was created in the corporation to develop its own disk systems, the result of this department was the first FUJITSU disk systems, released more than 40 years ago. The figure shows the general history of ETERNUS proprietary disk systems over the past decades.

    Since the end of the 90s, along with storage systems for connecting only to mainframes, interfaces for connecting to open systems began to appear. First of all, at that moment, of course, to UNIX systems. What immediately catches your eye when looking at the picture: the main difference from the huge number of today's manufacturers is the lack of acquisitions and “occasional purchases” that we very often see on the market in the last decade.

    In today's product line, of course, there are several disk arrays, the figure shows only the flagship. But at the same time, the entire product line today is the result of many years of work by a single group of developers, and not the fruit of spontaneous purchases in the market, with the goal of including hiding current losses “correcting financial statements”
