Extreme Materials Cost Savings


ESS can radically reduce the materials cost of building high-speed all-Flash SANs.

ESS prefers parity RAID, reducing SSD counts.  ESS random writes faster to a parity RAID set (i.e. RAID-5, etc.) than can be written to a same-size RAID-10 set.  Accordingly, in all but the smallest RAID-sets, it uses fewer SSDs than would be the case with a high performance RAID-10 set.

ESS generates superior SSD durability. The patented linear writing process of ESS radically reduces write amplification, particularly in lower-cost consumer and read-intensive SSDs.  In a parity RAID environment, such SSDs typically incur total write amplification of 16:1 to 39:1 without ESS. ESS typically cuts write amplification to around 1.5:1 on a 24 SSD RAID-6 set - 11 to 26 times more write-efficient than native usages.  Amplification can be halved again with ESS-managed compression. In practice, ESS-managed consumer SSDs will be more durable than Data Center grade Enterprise SSDs.

Consequently, ESS dramatically cuts SSD storage expense.  Here's a table of the cost of building various all-Flash storage arrays using both traditional methods and ESS storage management.  In the presentation, we have shown several consumer or read intensive SSDs, as well as the cost impacts of an M5200, which is an exceptionally low priced data center grade SSD.  Each of the specified drives has the ability to last for five years while overwriting the entire drive once a day.  The table was prepared based upon market prices on 7/12/18.

In the above example we see that the least expensive solutions cost about a quarter of the cost of traditional systems based upon the use of Enterprise grade media.

The same principals apply to NVMe SSDs.  In the example below, all of the SSDs are Micron M9200s.  The read intensive ECO model has a purchase cost only about 4% less per gigabyte than the PRO data center model. One presumes that this pricing aberation will eventually correct itself.  None the less,.ESS management of the storage volume reduces SSD count, compared to RAID-10, while radically increasing random write speeds.  This cost differential can also be improved once larger RAID sets can be used as the result of new motherboard technologies.  Finally.  NVMe can also be configured dual port, and thus form  form the basis for dual ported systems which are much less expensive than current generation SAS SSDs.
