MaxTronic International Co., Ltd. Arena iSCSI Presentation: iSCSI vs. NAS Jan., 2013

Storage Environment DAS Direct Attached Storage SAN Storage Area Networks NAS Network Attached Storage 2

DAS FC / IP SAN NAS Application software File system Networking FC / SAS / SCSI / eSATA RAID Networking File system FC / iSCSI RAID NAS Networking 3

DAS - Direct Attached Storage Data storage connect directly to a server or workshop through Host Bus Adapter (HBA), there is no network between storage and host servers Storage Storage Server A Ethernet 4

SAN - Storage Area Networks A dedicated data storage network which can be accessed by multiple servers SAN LAN Client Server A Storage Data Command Storage Server B Client 5

NAS - Network Attached Storage A file level computer data storage connect to other device on TCP/ IP network Client Server B Ethernet NAS Client Server A NAS 6

Difference of iSCSI, NAS - 1 Storage Computer File Level File System iSCSI Storage Block Level Computer File System Network Attached Storage (NAS) uses File-Level protocols such as NFS or SMB/CIFS for remote files sharing. Same as traditional SCSI and FC interface, iSCSI require Block-Level access to the hard drives such as email servers, databases, and high usage file servers. 7

Difference of iSCSI, NAS - 2   NAS IP-SAN (iSCSI) Device RAW device + format type RAW device Internal Access File Level Block Level Flexibility Bad Good Scalability Poor High Protocol NFS/CIFS/AFP iSCSI Performance Low Suitability Small Files Big Files Share Concept Data Sharing Storage Sharing 8 8

Why 1Gb iSCSI? Low Total Cost of Ownership Deploy SAN infrastructure on the existing Ethernet infrastructure Share the 10Gb infrastructure NIC, switch, cables Leverage technology expertise The same technology as existing network topology No additional training needed Easy management and maintenance Upgrade performance from existing 1Gb iSCSI 9 9 9

IP SAN Structure 10 改圖: 用10Gb Switch 來換掉中央的FC switch Department 跟 data center 保留, 但是將FC RAID 改成iSCSI RAID, Hub 改成switch 其他改成Virtualization, Cluster 10 10 10

Modularized and ECO friendly Design Fully modularization, designed for easy configuration, easy field service, easy inventory management Shared modules for different platforms: Same controller module for 2U, 3U, 4U Same P/S module for 2U, 4U Same Fan module for 3U, 4U Same Cache backup module for 3U, 4U Eco Friendly design ROHS Compliance Smart FAN Control 80% High Efficiency Power Supply Disk Standby 18

Arena Data Care Features RAID Level Support RAID levels 1, 3, 5, and 6 to prevent for drive failure. Sustained read performance even in degrade mode. Disk Cloning A method to automatically copy data to spare disk and replace the sick disk. It could be configured to trigger by the following conditions: Over bad block threshold of disk. Detect SMART warning from disk. Disk cloning is to prevent a rebuild from ever occurring and having the unit in degraded mode. On-line Array Roaming Array member disks has recorded specific Identification when original RAID system or controller faulty, the function provides a easily way to recognized data back by just move member disks to the same model and working RAID system. Array Recovery A embedded utility to rescue array set back from a fatal error of when parity array (RAID 3/5/6) unexpected lose too many disks and makes array fail. Block 6 Block 5 Block 4 Block 3 Block 2 Block 1 Parity (5,6) Parity (3,4) Parity (1,2) Sick Cloning Fail Roaming Working 1st Disk Fail 2nd disk Fail RAID 5 Fail~ RAID 5 OK Array Recovery 19 19

Utility Highlights PathGuard™ MPIO RAIDGuard Central™ (RGC) A specialist software utility focusing on I/O load balancing while increasing performance by leveraging end-to-end I/O path failover and failback, and Multiple path to each device. This software is available in all Redundant series which ensuring business continuity in any event of performance is a priority. RAIDGuard Central™ (RGC) A free centralized management software utility to provides centralized monitoring multiple RAID systems by through Ethernet at a local area network. Easier install RGC to a normal PC as an agent and then any PC/server could monitor to RAID system remotely. Allow customer to warning the engineer real-time with mail sending and most popular web messenger: MSN. 20 20

Feature Highlights MaxSure Arena unique F/W feature to support SED (Self Encrypting Drive), the drives are embedded with encryption ASIC and encryption key, to encrypt/decrypt data write / read to the drives automatically. The MaxSure are the 2 features for SED : Instant Secure Erase Authentication Key Management Encryption Key Encryption ASIC Embedded-in LUN Masking LUN (Logical Unit Number) Masking is an authorization process that makes a LUN available to some hosts and unavailable to other hosts. LUN Masking is implemented primarily at the HBA level. LUN Masking implemented at this level is vulnerable to any attack that compromises the HBA. LUN Masking support by storage is important because Windows based servers attempt to write volume labels to all available LUN's. This can render the LUN's unusable by other operation systems and can result in data loss. 21 21 21
