3 Storage Service at NIIFI NIIFI partners may apply for storage space as block devices. These could be configured as required and be accessed from partner's side as iscsi target devices via IP-network and iscsi protocol. Therefore, it is important t to have a basic understanding of volume management and iscsi protocol. Four mid-range storage devices (Fujitsu ETERNUS DX80) serve as a basis for the storage infrastructure. These all have the same 1Tbyte NL-SAS disks to provide a gross total capacity of 120Tbytes each. Two each of four devices are installed at the regional centre of NIIF at the College of Dunaújváros and at the University of West Hungary. All of these storage nodes are connected directly to the HBONE network backbone via Gigabit Ethernet on four ports each. 2

6 Redundant & hot-pluggable components Main components are redundant and hot-pluggable, such as controllers, power supply units, cooling fans and hard disk drives. CM#0 SCU Host Interface Controller Enclosure Panel PCI-E. Controller interconnect Host Interface SCU CM#1 Failed Components are hot swappable without stopping the system. NAND Flash LSI Monitor PLD RoC Expander CACHE CACHE RoC Expander LSI Monitor PLD NAND Flash Hot expansion of disk drives. PSU PSU Firmware can be upgraded without stopping operations. Drive Enclosure EXP#0 Monitor PLD Expander Panel Expander Monitor PLD EXP#1 PSU PSU Highest availability CM: Controller Module, EXP: Expansion Module, PSU: Power Supply Unit, SCU: System Capacitor Unit, RoC: RAID-On-Chip 5

7 Cache Protector When power fails, a capacitor maintains power until the cache content is saved to non-volatile memory (flash) Cache data is safe for unlimited time, it does not depend on battery capacity The capacitor recharges within 1 minute when power is restored High performance (write cache) available much sooner than with battery backup solutions No periodic replacement No maintenance necessary for capacitor Battery backup solutions must be monitored constantly and batteries need to be replaced every 3 years No time limit to restore the data in case of power failures Fast restart t after a power failure Maintenance-free capacitor 6

8 Data Block Guard 8-byte check code is added to every 512-byte data to control data integrity both on the drive and in the cache User data A0 A1 A2 A0 CC A1 CC A2 CC CC: Check Code Write Controller Module Read 1 3 Cache ECC Protected User data A0 A1 A2 A0 CC A1 CC A2 CC 2 2 Drive Written data A0 CC A1 CC A2 CC Apply Check Code Verify Check Code Verify & delete Check Code Improved data integrity beyond RAID 7

9 Redundant Copy All disk drives are monitored by the system Warning Starts rebuild automatically to Hot Spare if same type of error occurs repeatedly and exceeded a defined threshold After rebuild is completed, the disk drive showing signs of failure is disabled ncy Keep redunda RAID5 (4+1) Rebuild to Hot Spare Disk drive Hot Spare Disk drive Drive removal Drive incorporation Replaces failing drives to keep up redundancy 8

10 Data Encryption Key is generated automatically by the system Can be configured per volume Data can be encrypted LUN by LUN.????????? Encrypted????????? Not encrypted Removed encrypted drives are protected against unauthorized access 9

11 Energy-efficient Eco-mode When drives (RAID groups) are used only a few hours per day (e.g. for backup), Eco-mode is a simple way of saving power Drives are spun down or up depending on IO activity Drive rotation can be scheduled with ETERNUSmgr or ETERNUS GUI Applications can control drive rotation through CLI Business volume Stopped Stopped Stopped Stopped Backup volume 12 on am off 4 12 pm off Save up to 10% energy by spinning down less frequently used drives 10 Copyright 2009 FUJITSU LIMITED

12 SAS, Nearline SAS or Solid State Drives 3.5 SAS drives for mission critical data High performance and enterprise reliability 300GB, 450GB, 600GB / 15k rpm, 12 drives in 2U enclosure 3.5 Nearline SAS drives deliver cost-efficient capacity Large capacity at lowest cost 750GB*1, 1TB, 2TB / 7.2k rpm, 12 drives in 2U enclosure *1 available from FTS until stock lasts 25 SASdi 2.5 drives for more spindles per unit of fheight, ht consuming less power For alternative FC base units only ETERNUS DX80/DX90 with 2.5 drives can attach 2.5 and 3.5 drive enclosures Maximum drive count per model unchanged 146GB, 300GB, 450GB, 600GB / 10k rpm, 24 drives in 2U enclosure Enterprise-class SSD provide best IO/$ Excellent random reads and writes, lowest latency Good for highest IOPS demands with ETERNUS DX80/DX90 100GB, 200GB All drives of the same form factor (2.5 or 3.5 ) can be intermixed 11

13 SSD (Solid State Drive) Support High performance Super random access performance Lowest latencies (microseconds) Highest IOPS High reliability No motors and no mechanical parts multiple IOPS times (*1) *1: For random access Read: 16 times Write: 11 times New Low power consumption Semiconductor technology Use cases: Databases that require 1000s of IO/second HDD Power consumption HDD SSD 40% reduction New SSD Ideal for performance critical applications with ETERNUS DX80/DX90 12 Copyright 2009 FUJITSU LIMITED

14 RAID Migration RAID levels 0, 1, 1+0, 5, 5+0, and 6 available RAID migration enables moving data between different RAID groups without interrupting operation Migration to highly reliable RAID level: RAID 5 RAID 1+0 RAID5 450GB x 4 LUN 0 Unused drives 450GB x 4 Unused drives LUN 0 450GB x 6 RAID GB x 6 Mirroring Use the most appropriate RAID level l for your data Move data to more suitable drives / RAID levels online 13 Copyright 2009 FUJITSU LIMITED
