O Accelerator in a half height Gen8 server The Type mezz card and the Type B mezz card are distinguished by the mezzanine connector The type B card is slightly larger than a Type mezz card The amount of free RAM required by the driver depends on the size of the blocks used when writing to the drive The smaller the blocks the more RAM is required The table below lists the guidelines for each 80GB of storage For the latest information see the QuickSpecs sheet to the HP IO Accelerator for HP BladeSystem c Class at HP Customer Support http www hp com support The Remote Power Cut Module for the c Class blade mezzanine card provides a higher level of protection in the event of a catastrophic power loss for example a user accidentally pulls the wrong server blade out of the slot The Remote Power Cut Module ensures in flight writes are completed to NAND flash in these catastrophic scenarios Without the Remote Power Cut Module write performance is slower Writes are not acknowledged until the data is written to the NAND module thereby slowing performance When the Remote Power Cut Module is installed writes are acknowledged by the IO Accelerator controller to the driver The IO Accelerator controller then completes the write to the NAND module The IO Accelerators QK761A QK762A and QK763A for Gen 8 BladeSystem c Class have the power cut functionality embedded on the card They offer the protection without requiring the remote power

54. ns Monitoring and managing devices 20 Performance and tuning Introduction to performance and tuning HP IO Accelerator devices provide high bandwidth and high IOPS and are specifically designed to achieve low latency As IO Accelerator devices improve in IOPS and low latency the device performance may be limited by operating system settings and BIOS configuration To take advantage of the revolutionary performance of IO Accelerator devices you might have to tune these settings While IO Accelerator devices generally perform well out of the box this section describes some of the common areas where tuning may help achieve optimal performance Disabling DVFS DVFS is a power management technique that adjusts the CPU voltage and frequency to reduce power consumption by the CPU These techniques help conserve power and reduce the heat generated by the CPU but they adversely affect performance while the CPU transitions between low power and high performance states These power savings techniques are known to have a negative impact on I O latency and maximum IOPS When tuning for maximum performance you might benefit from reducing or disabling DVSF completely even though this might increase power consumption DVFS if available should be configurable as part of your operating systems power management features as well as within your system BIOS interface Within the operating system and BIOS DVFS features are often found under the AC
