2. TERM Definition

5. SANs support non-disruptive provisioning of storage resources

6. SANs allow multiple servers to easily share access to a storage array orframe

7. SANs provide better infrastructure for multi-pathing

8. SANs enable consolidation of storage peripherals

IBM System Storage DS3400 Summary_ 4 GbpsFibre Channel (FC) interface technology_ Direct-attach storage (DAS) or SAN solution —start with a DAS configuration and seamlessly transition to a FC SAN when ready _ Combination of 12 SAS or SATA 3.5" drives per enclosure _ DS3000 products are geared towards Small and Medium Business (SMB) and departmental environments, SAS and iSCSI attachment technologies are supported as well._ Expandable by attaching up to three EXP3000s for a total of 21.6 TB of storage capacity with 450 GB SAS or up to 48.0 TB with 1.0 TB SATA _2 U rack mount enclosure with 12 easily accessible drive bays _ Management software IBM System Storage DS3000 Storage Manager _ Supported drives Supports 3Gbps SAS 73 GB, 146 GB, 300 GB, and 450 GB SAS drives at 15,000 rpm speeds and SATA disks at 7,200 rpm speed _ Cache per controller512 MB battery-backed cache with 1 GB upgrade option

15. EMC CX3-40s System Storage Summary _CX3 series is midrange storage array market in performance and scalability. _The CX3-40 and CX3-40c offer an excellent combination of performance and scalability and are well suited for OLTP and messaging workloads. _ Storage Processor Enclosures (SPE) offer four Xeon® processors, 8GB memory, and four 4Gb Fibre Channel host connections. The CX3-40c also includes eight iSCSI ports for connection to hosts via Ethernet. _ Both models support directly connected hosts or up to 128 HA (dual-connected) SAN connected hosts. And, each array supports up to 240 disk drives for a maximum raw capacity of up to 119TB

28. Market Overview

30. Increasing complexity as the environment continues to grow,

31. Limits to the amount of resources available

32. Improve utilization & lower costs

33. Centralize management

35. Redundant management

36. Limited ability to share and protect information

37. Leverage common infrastructure

38. Meet consistent service levels

40. Standardize reporting and management tools

41. Manage more capacity per resource, and focus on other IT issues

42. Management is complex and time consuming

43. Configuration data is incomplete, inaccurate & uncorrelated

46. Storage capacity:

48. SAN System Support

50. Common Types Hard Disk

51. Common Types Connection_ Level 0: Striped Disk Array without Fault Tolerance. Also known as JBOD _ Level 1: Mirroring and Duplexing. Most commonly used for DB and applications. _ Level 3: Bit-Interleaved Parity. Used mostly for “streaming” data like audio and video _ Level 5: Block Interleaved Distributed Parity. Most used RAID level for balanced performance and cost. _ Level 6: Independent Data Disks with Double Parity. Provides block-level striping with parity data distributed across all disks. _ Level 0-1 : Mirror of Stripes _ Level 1-0: A Stripe of Mirrors FC: 146GB – 10K Rpm  Price: $1600 146GB – 15K Rpm  Price: $1955 SATA II: 500GB – 7200Rpm  Price: $2065 FC SAN iSCSI SAN (IP SAN) Performance of iSCSI SAN = ½ performance FC SAN (depend on connection speed as much)
