If I use the usable-size as reported by Ontap 9, our disks have a size of 2.42TB; there are currently 165 data drives on the aggregate, this result in 399.3TB (but the usable space is 359TB, because of WAFL overhead i suppose). Do you agree with that? Thank you Lorenzo 0 Reply All forum topics Previous Topic Next Topic 4 REPLIES cedric_renauld

Crushed Stone #1: Approx. 2″-4″ Wide Crushed stone grade no. 1 is the largest size with diameters ranging from around 2 inches to 4 inches. As this grade contains larger pieces, it's not suitable for shoveling and stones will need to be moved individually. Typical uses for gravel #1 include: Filling larger holes

Aggregate sizes up to 14 mm are common in single/single seals; 10 mm and 14 mm aggregate are usually used where there is sufficient traffic volume to warrant the use of large sized aggregates. For lower traffic volume roads and low speed environments, the use of 7 mm aggregate is often sufficient.

Aggregates larger than 4.75 mm in size are termed as coarse aggregates. These aggregates are obtained from stone quarries and stone crushers, the size between 4.75 mm to 80 mm. Good qualities of an ideal aggregate: These aggregate used for the construction of concrete and mortar must meet the following requirements.
We have used aggregate grading #67 (3/4") from ASTM C 33 in the past. We're considering going to a larger size such as #57 (1") or 467 (1-1/2") to reduce shrinkage cracks in the 24 inch thick walls. Our field personnel have expressed concern over placement of a 1-1/2" maximum size aggregate with a 2 inch clear cover.

• #4 Size: A larger stone of between one and two and a half inches in diameter, this grade of material is about the size of an egg or a golf ball. Because of its larger size, this stone isn't used for walkways or driveways, but instead forms a base for smaller sizes of stone. It can also be used as decorative stone in landscaping.
