INCITS, InterNational Committee for Information Technology Standards = iSCSI SANs Low cost flexible network architecture Simple security model and enforcement Interoperable open standard Simple to deploy and manage Fibre Channel SANs High cost, dedicated “network” Complex zoning of SAN fabric To avoid cross traffic between multiple host and storage types Single vendor solution Limited to qualified components and highly sensitive to firmware revisions Extensive vendor support required Professional services, support, and change management Sub-optimal resource utilization Challenge to load balance workloads across all disks and multiple controllers * * * * The SAN that SDC has implemented includes PS200E, PS300E, PS400E and PS3800XV arrays, containing a mix of Serial ATA (SATA) and Serial Attached SCSI (SAS) disk drives. * * No Single Point of Failure Battery protection = up to 72 hours Monitoring all the key component status in the array * GigE strongly outperforms classic (10BaseT) and Fast Ethernet (100BaseT) and other networking technologies. Some iSCSI HBA card can ever show 200MB/s network thoughput * Also, to reduce CPU loading, configure Jumbo Frames on each switch that handles iSCSI traffic. If your server is using a software iSCSI initiator and NIC combination to handle iSCSI traffic, you must also enable Jumbo Frames on the NICs to obtain the performance benefit (or reduce CPU overhead) and ensure consistent behavior * * * Time: 120 seconds Here are the highest results certified by each vendor through the Microsoft ESRP program. EqualLogic provides higher absolute performance and requires fewer disks to do it. These results include EMC and HP also. EqualLogic is supporting two times the users per disk as HP EVA 8000. We claim we have a DRAMATIC performance advantage. This graph shows a significant advantage, but is it enough to knock other vendors out of serious contention. Let’s spend a few minutes showing how our real-world ad
