Pure storage ssd sizes.

Accelerate business application development. Unify your cloud solutions. Finally while some flash storage vendors recommend a 4k block size for both redo logs and the database itself to avoid block misalignment issues pure storage does not. 06 06 2016 flasharray nvme by pure storage legacy vendors offering retrofit all flash arrays afas have been at the forefront of supporting big ssds 1 92tb and 3 84tb ssds over the last couple of years and have now announced support for 15tb ssds an impressive 4x increase.

We generated about 2 gigabytes of redo per minute. Pure storage s flasharray is assembled from a series of 2u storage racks and controllers which provide a raw uncompressed mlc ssd storage density of just under 3tb per u which is 3x lower than vanilla fc san mlc ssds such as the ramsan 810 from texas memory systems. Pure storage lab testing for our load test we ran the hammerora tpc c workload. Purity fa computes a hash value for each incoming sector and attempts to determine whether another sector with the same hash value is stored in the array.

The redo logs rolled roughly once a minute for all tests i e. Innovate with the modern data experience from pure storage. The item to bear in mind is that an ssd based array with 8gb or 16gb hbas using fibre channel can achieve extraordinary bandwidth with sub millisecond latency. When you zone this to a 4gb host there s a good chance that the host will cause back pressure unable to keep up forcing fame discards further down the path.

Since the pure storage flasharray is designed on a 512 byte geometry we never have block alignment issues. High performance inline deduplication operates on a 512 byte aligned variable block size range from 4 32k. In fact the majority of our customers arrays have weighted io sizes above 32kb rather than below 32kb. We used 20 logfile groups sized at 2 gigabytes first using 512 byte block size and then 4k block size.

Performance is completely independent of the block size. Protect and manage your data. However concerns about hybrid storage include access speed and latency as well as fears around security compliance and data portability. Flasharray is the first all flash 100 nvme shared accelerated storage designed for mainstream enterprise deployments.

We can see that the most popular read size is between 32kb and 64kb and the most popular write size is between 16kb and 32kb.
