WildFire ESS Technology Overview
 WildFire
Storage is based on EasyCo's patented Enterprise Storage
Stack, first developed in 2006. The stack is a software
layer designed to create a perfect storage stream. With our
storage stack, storage devices such as SSDs, hard disks, and
even USB sticks see perfectly aligned, long, linear writes,
regardless of whether the source data is linear or random.
These linear writes are immensely faster than scattered
random writes. They also radically reduce wear amplification
in flash media.
Perfect Flash Performance: the WildFire
all-Flash stack writes at the linear speed of the device or
array. This involves keeping the block IO patterns
"perfectly aligned" at all stages. An 8 drive RAID-5 array
with SSDs that linear write at 500MB/sec, can write random
data at 3.5GB/sec or 850K 4K random write IOPS. Larger
arrays have been benchmarked at over 2.1M IOPS. More
importantly, the reduced wear amplification of our design
preserves performance in a way that other solutions can't.
Minimal Flash Wear: our stack reduces the
wear amplification of Flash SSDs, as well as RAID
amplification and data amplification. ESS can improve
system-wide flash wear, for a given workload, by as much as
40:1. This lets you use less durable and less expensive
flash in storage devices.while still achieving durability
goals. For instance, consumer (2000-3000 endurance) flash
can achieve data center performance expectations. With
consumer flash, you can expect 5 year life even with an
overwrite per day and minimal over-provisioning.
Higher Data Integrity: a number of features
are designed into our storage stack to increase data
integrity beyond levels normally available in source media.
Unmatched value: Wildfire Servers are far
and away the value leader in Flash storage appliances, both
in terms of $/GB and $/IOPS. No one else is even close.
