Our Solid State product categories include Solid State Drives, or SSDs.
We define enterprise-class as products that include full data path error detection and surprise power loss protection.
In addition, our
SSDs have HPE SmartSSD Wear Gauge support, which provides diagnostic information and reports on the health of any given drive.
HPE Enterprise SSDs are available in three categories based on the customer’s application and workload level:
Read Intensive (RI),
Mixed Use (MU), and Write Intensive (WI). These categories indicate the number of drive writes per day (DWPD1) that you can e
xpect
from the drive. (DWPD is the maximum number of 4K host writes to the entire drive capacity of the SSD per day over a five-
year
period).
Workloads such as Read caching, Web Servers, Social Media, and Boot are more Read Performance driven. Workloads such as Busin
ess
Intelligence, Big Data Analytics, Virtualization tend to be more Write Performance driven.
Our Read Intensive SSDs are typically focused on Read Performance with an Endurance less than or equal to 1 full drive write p
er
day.
Our Write Intensive SSDs are focused on Write Performance with an Endurance of >=10 full drive writes per day (DWPD).
As
an example, if we have an 800GB Write Intensive SSD with an endurance of 10 Drive Writes per Day, it means that customers can
write to the entire 800GB capacity of that SSD 10 times per day, and the drive will last for 5 years. Positioned in-between RI an
d WI,
we have products with Balanced Read and Write Performance that we call Mixed Use (MU), with an Endurance of typically ~3 DWPD
.
All of our Solid State products have performance that can be 80x or more when compared to rotating hard disk drives. Today
s NVMe
SSDs connect directly on the PCIe bus with the processor and memory. They are used in applications that require the highest
performance, such as Online Transaction Processing in the financial industry. Low Latency NVMe SSDs are positioned in the Wr
ite
Intensive category and are uniquely positioned for workloads that require the lowest latency, best QOS, and high performance.
Using the above figures along with our HPE SSD Selector Tool
you can quickly determine wh
at SSD/AIC solution might best meet
your needs. You can also compare specific capacity, performance attributes, and server compatibility.
