    Abstract: Techniques for improving access time in data storage systems are disclosed. These techniques can be used to prevent undesirable access delays that are often experienced in conventional storage systems. “Slow-access” can be defined as an access operation that does not successfully complete within a predetermined amount of time. The “slow-access” time can, for example, be defined based on a system requirement, specification, or a particular need of a specific application. As such, when detected “slow-access” indicates a potential performance problem that can manifest in undesirable effects. A data storage system is evaluated for potential performance problems by scanning it for “slow-access.” In addition, preventative measures are taken to prevent occurrence of a “slow-access” once it has been identified. These measures can prevent the undesirable effects experienced in conventional storage systems. This also means that specific system or application requirements can be certified and met.

    Abstract: Improved techniques for accessing data storage systems are disclosed. These techniques detect, correct and prevent undesirable access delays experienced in storage systems. “Slow-access” refers to an access operation that does not successfully complete within a predetermined amount of time. When slow-access is detected, an attempt is made to provide data by other means rather than waiting for the access operation to eventually complete. By way of example, parity information is used to generate data rather than waiting beyond a predetermined amount of time for a “slow-read” operation to complete. In addition, preventative measures can be taken to avoid reoccurrence of a “slow-access” operating once it has been identified. These preventative measures, for example, include rewriting the same data to the same data section that caused the slow-access problem or remapping the section to another section in order to avoid the same section of data to cause another slow access problem.

    Abstract: A process and furnace for melting glass is set forth wherein the majority of the combustion energy over the melting zone of the furnace is provided by oxy-fuel combustion while a majority of the combustion energy over the fining zone of the furnace is provided by air-fuel combustion. In many cases, it will be preferable to provide greater than 70% and up to and including 100% of the combustion energy over the melting zone by oxy-fuel combustion and greater than 70% and up to and including 100% of the combustion energy over the fining zone by air-fuel combustion. By proper tailoring of the combustion space atmosphere through oxy-fuel and air-fuel firing, the present invention can result in an improvement in glass productivity and quality. The present invention can be applied in the construction of a new furnace or can be applied to existing air-fuel furnaces.
