July 2014 Last two months, we presented the topics
of how storage system availability affects business operations and the causes
of storage system downtime. In this month’s newsletter, we examine the cost
of system downtime. Importance of Storage System Availability ·
Computer system uptime depends
heavily on proper storage system operation. ·
Nearly two out of every three
system failures is caused by downtime of the data storage system, and not
servers or software. ·
Regardless of the downtime
source, the effects are predictable: sales, services or supply chains can
come to a screeching halt. Causes of Storage System Downtime ·
Downtime calculations should
include all periods in which a system becomes unavailable. Because systems
are normally taken offline during planned system maintenance, downtime measurement
should include both planned and unplanned downtime events. · Unplanned
downtime events: hardware failure, human error, software failure, and natural
disasters. · Planned
downtime events: equipment life cycle operations and maintenance operations. Cost of IT-induced Business Downtime The
Aberdeen Group, an international authority in researches focused on helping
businesses across 17 different B2B technology disciplines improve their
performance, conducted a two-part (18 months apart) “cost of downtime” survey
with data collected form 134 organizations. The
focus of this research is to quantify the current cost of IT-induced business
downtime. Participants are scored against the following performance criteria:
number of actual business interruptions per year, the average length of time
of business interruptions, and the length of time required to recover 90% of
operational functionality. ... Learn more >> |
