Storage configuration details
Internal storage
The DL980 G7 OLTP recommended configurations use four internal drives configured with RAID1 for the OS and 11gR2
software. The server supports up to eight internal drives, so additional drives can be added for staging data, logs, or
other requirements.

External storage
VMA3210 Memory Array
Hewlett Packard’s VMA-series Memory Arrays are external systems offering high capacities of solid state storage, using
hot-swappable flash memory devices. The VMA-series Memory Arrays feature rackable external solid state storage in
capacities ranging from 5TB to 10TB per Single-level Cell (SLC) array. Multiple arrays can create scalable capacities up to
petabytes of solid state storage.
The arrays are designed for customers who need low-latency response times, very high I/O performance, and large
capacity. Solid state memory technology provides these storage products with no-moving-parts reliability and low
power and cooling requirements. These arrays offer a choice of PCIe-direct attach or Fibre Channel SAN attach. PCIe-
direct attach with rackmount servers offers lowest latency speeds for single-server applications. Fibre Channel SAN
attach with either blade or rackmount servers allows multiple servers to operate on the same shared data, with
practically unlimited amounts of solid state storage.
The VMA3210 Memory Array is a 3U appliance that provides solid state storage to servers. The VMA-series Memory Array
eliminates the seek-bound limitations of rotating disk storage and delivers significant application performance benefits
over traditional storage systems that utilize hundreds of hard disk drives (HDDs). VMA-series Memory Arrays have
practically unlimited scalability – the very large capacities that can be created with VMA-series arrays enable users to
place entire databases into solid state memory without needing to architect their solution around limited capacity solid
state drives.
Using a massively parallel architecture with distributed garbage collection implemented in hardware, each VMA-series
Memory Array with Single Layer Cell (SLC) NAND Flash delivers sustained DRAM-like performance that is an order of
magnitude faster than a similar size HDD array:
 1.4 GB/s bandwidth
 350K Random Read IOPS
 Delivers up to 240K Sustained Random Write IOPS (4K block with RAID)
 Up to 10TB raw capacity and 6TB Usable flash storage (if configured for best performance)
 Low latency Flash 4 + 1 parity RAID
– Reads: 80 micro seconds
– Writes: 25 micro seconds
– Non-blocking Erases ensures consistent low-latency Reads
 Significant application performance
 90% reduction in cost, power, and cooling for similar performance
 Power-safe writes without batteries
