Recommended Reading: Symantec/Intel Architecture Compares to Flash Array Architecture for Oracle Databases

It certainly is worth looking at the latest white paper from Symantec and Intel.  They have dropped a small bomb on the flash array party. In a white paper, Software-defined Storage at the Speed of Flash, the duo provide a look at a nice Oracle database architecture where they show both price/performance advantages and comparable performance to flash arrays from Violin Memory, EMC and a CISCO solution.  Two Intel R1 208WTTGS 1RU servers were outfitted with four Intel P3700 Series SSDs, 128 GB DDR4 Memory, Symantec Storage Foundation Cluster File System 6.2, Oracle 11gR2 and Red Hat Enterprise 6.5 OS. The two servers are interconnected with high speed dual-port Intel Ethernet Converged Network Adapter. The white paper goes into quite a bit of detail and offers a nice chart comparing the converged solution with the flash arrays solutions.screenshot_475

 

 

Recommended: Flash Accelerating Oracle RAC in 16RU & VMware Power Savings with Local Flash

Fusion-io, Dell, and Mellanox have built a very small footprint (16RU), extremely fast, and price-sensitive reference architecture for Oracle RAC 12c. It is very impressive on a number of counts.  It further highlights the move to using local flash storage over remote flash storage arrays.  This solution aims at reducing hardware sprawl and power consumption by achieving higher performance in a smaller footprint.  From the description – “This reference architecture features four Fusion ION Accelerators and four Oracle RAC database nodes all connected through redundant Mellanox SX6036 switches. Each ION Accelerator in this reference architecture uses a Dell PowerEdge R720 with three 56 Gbps Mellanox ConnectX-3 InfiniBand cards and four industry-leading Fusion ioDrive2 2.4TB flash storage devices for a total of 9.6TB of all flash storage. Each of these ION Accelerator units fits in 2 rack units (2RU) and delivers well over 645,000 8K database IOPS and up to 12 GB/s sustained throughput. Data redundancy is maintained across pairs of ION Accelerators using synchronous writes, thus providing system and data high availability.  The Oracle RAC nodes consist of Dell PowerEdge R620 servers. Each two-socket server consumes a mere 1U of rack space and yet is capable of pulling 1.4 million 8K IOPS from the ION Accelerator storage layer as measured by the Flexible IO Tester utility.  The Oracle RAC nodes are connected to the ION Accelerators through redundant Mellanox switches. Each Oracle RAC node sees the ION Accelerator storage as simple multipath block storage. The multipath devices are aggregated by Oracle ASM to create a large and powerful diskgroup.  Expanding the size and performance of the database is as easy as adding more ION Accelerator devices to the ASM disk group.”  The links to the article and the Reference Architecture follow.

Increasingly, software vendors  see the virtue of putting their flash storage locally on the server.  For example, VMware engineers wrote recently that by replacing array shared storage with PCIe flash card storage on the servers they could substantially reduce power consumption and maintain high levels of performance.
