  1. DotHill Systems Storage Systems Technologies Base - 2007 Include 2002/3000

  2. The R/Evolution Architecture • Eco system • Eliminated Litium battery to protect cache data • Going to have MAIDtechnology • DC power supply models • 2.NEBSIII, MIL-spec compliant systems • 3.Ease of maintenance with modular design • 4.Mixed use of SAS/SATA/SSD drives • 5.Allow system upgrade by replacing controllers • 6.Data Management Services for better data protection • 7.Great capacity from entry level systems, covers HA systems DotHill NDA material

  3. iSCSI FC SAS 2000series chassis Choice of iSCSI, SAS, FCSystems Extend disk capacity Transaction processing 2330(iSCSI) • Casual IP-SAN • Using existing network infrastructure, configure cheap and free networking • Accessing Gigabit Ethernet bandwidth IPネット • DASmarket • Suitable for Blade servers • Eliminate costs FC-SAN SASadapter servers 2330 (5730) 2730 2530 SAS I/F market （Midrange, Entry) • 2008 - $167M • 2009 - $485M • 2010 - $1,026M • 2011 - $1,635M SAS based server will increase more year on year. SAS(2530) and Fibre Channel(2730) • 1200MB/s vs. 400 MB/s • SAS has 3 times bandwidth of FCin theory • Drive power 3.3W vs. 12.5W • Only 25% of power needed with FC drives • Choice with server I/F or environmental need DotHill NDA material

  4. Patented architecture • Environmentally, economically better cache protection • Battery free configuration • Eliminate need of replacement (maintenance free) • supercharge on power up • Redundant cache optimization冗長性のあるキャッシュの最適化 • Very fast write performance • Reduce controller CPU usage and eliminate use of bus bandwidth • Disk Array based data management (DMS) • Snapshots : 16~ 256 with license Controller firmware • Online RAID expantion • Adjustable rebuild priority • LUN configuration • Easy operation • volume based cache setting • Scrub virtual disks • Non disruptive FW upgrade Maximum of 12 3.5” drives on (only on) 2U12 chassis • SATA – 250, 500, 750GB, 1TB, 2TB • SAS –300GB, 400GB, 600GB • Intermix SAS/SATA drives, on any slots • Hot-swappable har disk drives • Maximum of 56/96/108 drives (2000/2002/5000) Front panel of 2000/5000 series Supports various application needs DotHill NDA material

  5. RAID controller • 6th generation: 2000/5000, 7th: 2002, 8th: 3000 • RAID 0, 1, 3, 5,10, 50, 6 • Single or Dual controller configuration • 1GB/ 4GB cache size (~7th/8th) • 2730 performance • 93K IOPs • 25K IOPs disk drive IO • 865 MB/s disk drive throughput • 2730T performance • 124K IOPs • 31K IOPsdisk drive IO • 1154 MB/sdisk drive throughput Array Management • Configuration and Management • Environmental monitoring and alert • EmbeddedWeb GUI and/or CLI • Customizable management panel Power supply and fan module • Hot-swapable • redundancy Back panel of 2000/5000 series Modular host I/F • 4 x 4Gb FC 27xx (8 ports 5730) • 4 x iSCSI 23xx • 4 x SAS 25xx Improved QoS DotHill NDA material

  6. Ease of maintenance by modular design • R/EvolutionArchitecture : • Modularity, Redundancy • Ruggedize Storage • Less development costs • Rich family of products Improve R.O.I much by reducing operational costs. DotHill NDA material

  7. Store signature for On-board Storage Controller cache validity of Flash CPU Subsystem removable NV memory Remain Powered during Flush Operation Powered-down during Flush Operation CPCI PWR_STATE[1:0] Power DDR-SDRAM DDR Monitor and Interface FLUSH_STATUS[1:0] Cache Memory Backup Logic Reset RAID Primary Controller Power Compact Flash-II Socket IDE Backup Power Interface Power Regulators (CF card or uDrive) EcoStor Clock Source EcoStor Technology Cache backup technology without battery • Cache data is protected even with power outage • On power-up, Array writes-through IO until Capacitor/Battery is fully charged • several Minutes (Capacitor)vs. several Hours (Battery) • Lasts ~10 years. Eliminates periodic maintenance downtime caused by replacing battery. • Environmental healthy technology DotHill NDA material

  8. W W-ack Traditional Cache Protection SAN SAN 1) Host initiates write command 3) Second controller acknowledges write 2) Write is mirrored to second controller Controller 1 Controller 2 Host Interconnect (FC, SAS, etc.) Host Interconnect (FC, SAS, etc.) PCI PCI Disk Interconnect Cache Processor Processor Cache Disk Interconnect 4) Controller acknowledges successful write SAS Drives DotHill NDA material

  11. Sample Storage Configuration 2002/3000 • 2U12 chassis : 96 drives • 2U24 chassis: 144 drives Mix and Match JBODs • 2722 expander cable maximum length is 2m in toｔal • 2u24 RAID to 2u12 JBOD will require “conversion cable” • 600 mm limitation to next • Intermixing JBOD types also supported Note: You cannot support a 2u24 JBOD behind a Neptune controller DotHill NDA material

  12. RAS/Environmental/Low Power • EcoStor quick charges Super-Capacitor • Eliminate Pb and Battery • 5730: NEBS Level-3 certified, Others: Compliant • Supports DC PSU, reduce total power consumption Rapid temparature transition (5o to 50oC) Earth Quake Max 3 Richter scale Contaminated air, dusts Static electrical shock of max 15,000 v • Telcordia Technologies / U.S. (former Bellcore)NEBS Level-3 strandard certified. NEBS was developed to standardize equipment that would be installed in a typical Regional Bell Operating Company (RBOC) central office (CO). This would result in lower development costs and ease the equipment's introduction into the network. DotHill NDA material

  13. Data Protection Features (DMS) Protect covers from logical failures to site failures • AssuredSnap (Snapshots) • Point in time logical image of the master image (16 to 256, 1000 snaps) • Protect data from human error or data corruption (roll back) SnapShot can be mounted and used by other servers. Modifiable Read-Write or Read-Only option Have tremendous effects for reducinf backup windows. • AssuredCopy (Volume Copy) • Complete point in time clone of the volume • Additional protection or use of the master volume ＊　Going to provide remote replication and re-joinable mirrors DotHill NDA material
