Cisco acquired on October 29th 2013 Scalable Solid-State memory systems that accelerate application performance and simplify data center virtualized environments. Currently not to be sold as part as a Vblock, you can add as additional outside the Vblock but will not be supported by VCE Why WHIPTAIL Enables workload to rapidly transact process, and analyze data into business intelligence, leading to operational and strategic advantage. Through a modular and scalable solid state memory platform, coupled with RaceRunner intelligent software Hard Disk Drive Performance Limitations Access Times Rotational Latency The Time the disk platter access the data and rotates the platter to the next sector where the data is stored If the disk have spun past the data , the HDD has to wait for the rotation to complete the data read/write Seek Time Command Processing time Settle Time This performance has stood still since 1999, when the first 15K RPM disk became available All other media continue to improve performance at a pace RAID penalty For every write IO in RAID 6 there are 6 IO Operations required. Where in HDD you use around 30% of the disk and the rest is overhead (Short Stroking) WHIPTAIL can use 75% of the disk with 25% for management Virtualization : The IO Blendar Blended IO, each VM has a read/write and one VM has to wait tell the VM's read/writes are finished, this could have the head jumping around the disk and all the reads and writes are all over the disk Atlantis ELIO Pipelines Writes to the disk SSD Doesn't care 10 x throughput bandwidth 100 x IOS's performance improvement 1000 x less latency NAND based flash memory are mailer then HDD SSD's are typically more resistant to physical shock, run more quietly and require less POWER and COOLING For eery $1 in hardware the creates heat it takes you $3 dollars to cool that, assuming that you have hot and cold isles More Data Faster Data Complex Data Volume Capacity Volume Based storage Velocity Time Accelerate the write and read of application workload data Variety Understand different solutions and formats Hot Data This is WHIPTAIL plays Warm Data Cold Data 8 Racks of HDD for every 1 Rack of SSD in DC footprint Target Applications Workloads Email VDI and Virtulization Infrastures Fusion IO (this will not go away) PCI Single Application/host based AFA= All Flash Array This is where the WHIPTAIL plays This can be used with multiple work loads (MWL) Cisco Solid State Systems SSD and NAND Flash NAND Flash: Non-volatile memory SSD: A disk that has no moving parts; not based on NAND flash NAND Flash is everywhere Your computer BIOS Compact Flash SmartMedia Memory Stick NAND Flash memory is a type of EEPROM chip consisting of cells with two transistor separated by an oxide layer: A Floating Gate and Control Gate NAND logic all inputs='1' > output='0' all other combinations > output ="1" Wear Cycles Single Layer Cell 30K r/w operations before they fail Multi Layer Cell 2k-5K r/w operations before they fail This is rather small amount of times Invicta is saying that the wear time for their AFA is around 7 years for when the performance drops (under warranty) If the drive and there is a performance problem in a cell they will replace the drive within 7 years (this doesn't require smartnet) OEM for the FLASH is (Micron) and uses a MLC TRIM TRIM enables Garbage Collection to skip invalid state rather than moving it; reduces the number of erases UCS Invicta OS: Enhanced Flash Management Receive UCS Invicta Block Translation layer (BLT) Organizes Random Data Patterns for Flash Writes (Think Tetris) On going process managed by the local controller RaceRunning = Invicta OS   Whiptail and UCS  |
