Chicago's yearly precipitation comes in at an average of about 36 inches (910 mm), but during the summer, rain arises from short-lived hit-or-miss rain rather than actual prolonged rainfalls, and thunderstorms also occur with regularity at night. In a normal summer, temperatures exceed 90 Â°F (32 Â°C) on 23 days.
You might have heard someone mention flue spaces for rack storage, and wondered what flue spaces are and why they are needed. Flue spaces are clear lines of sight from the floor up to the ceiling within rack storage areas. There are two types of flue spaces - transverse flues and longitudinal flues.
Slack space is the unused space between the end of the actual file and the end of the the defined data unit (cluster). A cluster is the smallest unit of storage that the operating system can deal with. When a file is written, and does not occupy the entire cluster, the remaining space is slack space. For example, assume that the OS uses a 4k cluster and 512 byte sector, meaning it writes data in 4k increments made up of eight 512 byte sectors, regardless of the actual size of the file being written. This means that if a 2000 byte file were written to this cluster the remaining 2096 bytes would be slack.
