Benefits

• NVMe is the new standard for PCI Express (PCIe) SSDs

• Architected for Flash Storage with minimal CPU overhead

• Works directly with PCIe interface

• No SCSI protocol overhead resultingin very fast response

• 5x to 10x IOPS improvement overSAS based SSDs

• Low latency of 100s of micro seconds

• Improves database performance and reliability

NVM Express SSDs

• Eliminates the protocol transformation to SAS

• Interfaces with root complex over a four-lane PCIe Gen3 interface

Conventional SSDs

• Flash data is first transformed to SAS protocol

• Bandwidth to each SSD limited by SAS-3 bandwidth


Support Swappable*, High-Bandwidth Flash*Hot swapping during operation may not be recommended in some cases.

NVM Express (NVMe) – High IOPS Flash Implementations

22

Uses same 2.5-inch small-form-factor (SFF) drive bays as hard drives and conventional SSDs

Four drive bays in the two-socket enclosure are designated as NVMe capable

Oracle’s unique design connects the disk backplane to an internal PCIe switch that occupies one of the internal PCIe slots and bypasses the SAS controller.

TESTIMONIALS

CHALLENGES/OPPORTUNITIES

• LifeLock is an identify protection company and security is very important

• Experiencing database latency delays of 80-3000 ms

• Needed to quickly grow the database storage to meet business demand – traditional storage environments couldn’t be expanded quickly enough

RESULTS

• To guarantee the security of customer data incorporated Oracle's Transparent Data Encryption

• No more database latency issues with just 4-6 ms latency out of the box with Oracle Database Appliance

• Completely configured with the RAC databasewithin one day

CUSTOMER PERSPECTIVE

Oracle Database Appliances are amazing. You reduce your complexity, you have an entire environment that's set up in the appliance and you're done in a very short amount of time. Traditional storage capabilities just don't allow for that.– Jacqueline Hufford-Jensen, Sr. Manager, Database Administration, LifeLock

Summary of X6-2S/MSimple, Optimized, Affordable

• Completed Oracle’s offering by targeting the smallest and medium size markets

• Even easier and faster to deploy than the hugely successful ODA X5-2 HA

• Lowest OpEX (operational expense/running costs)and CapEX (capital expense/hardware cost) of all ODA

• Just like X5-2 HA, S & M allow linking to the cloud

• SE2 can be used for small companies

• Very high performance for OLTP databases(many small and random read/write requests)

45

ODA X5-2 HA (High Availability)Still the No. 1 ODA solution without compromises.

• The ODA X5-2 HA is still the most powerful, flexible, secure ODA model with highest availability

• The X6-2S and X6-2M are stripped down models with significantly fewer features but compensated by extremely low entry price

• Choose X6-2S/M over the X5-2 HA if the customer:

– Only requires a single instance database

– Does not require RAC (Real Application Cluster) for redundant DR (disaster recovery) or Fail Over

– Does not or will not need virtualization

– Is happy with limited application support

– Has small databases

– Has extremely limited physical space

– Predicts limited-medium IT growth
