Upon launch in the latest generation CX4 series storage arrays supported fibre channel and iSCSI front end bus connectivity. While this somewhat lessened the advantages of Aviion in the marketplace, and was a source of internal corporate friction, it allowed the company to sell higher volumes and popularize the brand. West realized the potential for more advanced and openly compatible data-storage devices, as did competitors such as Digital Equipment Corporation with their StorageWorks product.
Patented inthe Clariion disk array had some interesting features that later became standard in the data-storage and computing industry.
Features mentioned in the patent paperwork included optional hot swapping guide rails for proper electrical contact, and a method to lock the drives in place once they were secured in the disk enclosure. Other notable features include industry’s first dual active-controller design, mirrored write cache, full system redundancy and hot repair. InData General’s Clariion division took the unusual step of adopting an emerging standard — Fibre Channel.
From there, the Clariion range grew into a faster, more expandable midrange storage platform, culminating in the FC under Data General.
A special model was the IP, offering IP-based access to storage. Within a couple of years, [ when?
Later inthe line was expanded to include a new entry-level storage system, the CX The Clariion is built on an Intel platform and has quite unique software layer: The form factor is a half-width cariion or 2U device known as an X-blade, two of which are mounted side by side in the storage processor enclosure.
This provides a fully redundant active-active configuration, with both storage processors serving requests and each acting as failover for the other so that initiators see the array as active-passive. An integrated UPS provides security for data in the event of power failure.

Storage is fibre-attached, initiators may be fibre- or IP-attached, the architecture supports both on the same array depending on configuration. Storage is connected via back-end loops with up to drives per loop, the drives are contained in Disk Array Enclosures DAEs of 15 drives each. In the event of power failure, this space is also used to store the contents of the write cache so that all writes are completed on restoration of power. Management of the Clariion is usually through inbuilt Java-based management software called Navisphere.
Advanced functionality of the Clariion is licensed and enabled through software. This could cause issues with unsuspecting clients, one path would always appear dead. Accesses to it would trigger a reassignment of the LUN to the other controller, a so-called trespass.
This had severe implications on IO performance, and on older models like the models, this could cause a controller to crash if the system was directly loop attached to multiple IO-heavy hosts.
The second controller would then take over the load from the first one, crash due to the additional LUN trespasses. By this time, the first controller comes up and is missing a partner to sync to. The AX is available in four configurations which differ in connection and number of controllers.
The base version has only place for 12 disks. Models of the CX series come in two configurations: Fibre Channel transfer speeds max. The exception is the CX, which is FC only.
The names of the iSCSI models end with an ie.

Later the series was refreshed to include the CX and the “i” and “f” identifiers. All current fx4 when? Each CX4 array consists of dual redundant hot-swappable components including storage processors, mirrored cache and battery backup, as well as redundant power supplies. Solid State Flash drives offer a significant performance advantage over mechanical drives and provide a new storage tier which EMC calls Tier From Wikipedia, the free encyclopedia.
