IT Support: Understanding IT Jargon

IT consulting jargonIn many companies that have adopted a managed programs model for IT support,  both employees and managers that work in tech-heavy departments have found it useful to become more conversant with some of the jargon that IT support personnel sometimes use.  Every so often, it can be useful to have a refresher course on some of the terms that are pertinent to newer technologies, since the tech world is always surging ahead with new ways to lower costs and increase efficiencies.  Managers who do not keep up with the ‘lingo’ can find it more difficult to interact efficiently with the managed programs personnel that visit the premises to provide a regular, scheduled round of support and maintenance.

SSD Terminology

We are all familiar with hard drives, but one of the newer technologies to gain prominence in recent years is the solid state drive or SSD.  These are storage hardware devices that use flash memory to contain data.  Since they have no parts that move, they are highly durable and reliable, although more expensive than the traditional hard disk drives.

If your business uses SSDs or is considering transitioning to them, you may need to be familiar with some of the terms IT companies use to discuss them.  One of the most important is ‘SSD over-provisioning’.   This refers to a situation in which extra storage availability is included in a flash SSD.  What makes it ‘over’ provisioned is the fact that this extra capacity is not visible to the host controlling device.  While this may seem at first to be illogical, it has a salient purpose: to increase drive longevity by not using all sectors continuously to full capacity.

Tier 0

IT support personnel may refer to 'Tier 0' from time to time.  This simply refers to the level of storage that is fastest in the SSD array.  Because it is fastest, it also tends to be the most expensive storage level.  Companies that need certain applications or data to be available without delay will want to make sure that they are hosted in Tier 0 storage.  This will help to reduce the need to swap data in and out of fast memory, operations that can result in wear and tear on systems after millions or even billions of operations.


This term simply refers to 'resistive random access memory'.  RRAM devices feature a different electrical resistance that can enable rapid switching speeds.  For more information on the possible benefits of SSD storage in your business, contact iCorps today.
