Free Online Library: Enabling cost effective global enterprise Storage Area Networks using 10 Gigabit Ethernet. Especially with the advent of Gigabit Ethernet, it has become affordable to attach iSCSI storage servers simply as remote hard disks to a computer network. Overhead from iSCSI itself is pretty much neglectable (except for very high IOP figures and very low actual bandwidth) and decent switches will be very close to the theoretical maximum. We reserve 10GB, so you can't occupy the entire volume with an iSCSI LUN, so it should only end up 99. Simply plug in a USB drive and the user can retrieve information about the system for tech support, upgrade firmware, reset passwords and much more. Synology doesn't disappoint. Slow Network Performance on Server 2012 R2 Core March 29, 2014 eric 5 Comments In going through the motions of upgrading our Hyper-V cluster from 2008 R2 to 2012 R2, I had originally started to deploy a Hyper-V 2012 cluster. Learn the best practices for running SQL Server on VMware including 1Gb and 10Gb iSCSI, configuring memory, CPU resources, clustering, and slow disks. While it isn’t on the Synology compatibility list, a $17 Mellanox ConnectX-2 card will work, if you do need 10gbit (more info in the networking section).

For example, an administrator allocates all or a portion of a RAID volume (RAID 1, RAID 5, SimplyRAID, etc. HBA 10GbE NIC 8 - iSCSI Storage (Direction connection to QNAP NAS via CAT6e Copper) HBA 10GbE NIC 9 - Spare (for now - but will look at dual path redundancy soon) The above VMNIC8 (10GbE) is connected directly to one of the four 10GbE ports on the QNAP NAS unit - directly without a switch. More than Veeam block size, it's useless to create a stripe size bigger than the filesystem you are going to use on top of it. Theoretically we should be able to get up to 125 MB/s on 1 GB ethernet with zero network congestion. During the initial testing and performance analyzing time, I have noticed very slow network inside virtual machine guest OS. iSCSI is OK, but use caution, as it can saturate if you start pounding multiple databases. You may have to register before you can post: click the register link above to proceed. storagedude writes "10 Gigabit Ethernet may finally be catching on, some six years later than many predicted. Fibre Channel vs. Aggregating ports together pools the resources to create a highly available configuration, iSCSI or other services then use the port aggregation group to distribute I/O and provide redundancy. Networking configuration can make a real difference to Hyper-V performance. It is essentially composed of 3 SSD drives connected to the Intel motherboard SATA controller, and then a RAID0 array composed of 4 15k SAS disks. iSCSI is slow Point 1 : 1Gb vs multi-1Gb vs 10Gb: It is pretty save to say any higher-end enterprise class IP SAN offers multiple gigabit ethernet ports for redundancy and performance. With software iSCSI initiators, any supported 1 Gb Ethernet or 10 Gb Ethernet adapter for Lenovo servers is compatible with the ThinkSystem DS6200 iSCSI storage. The benchmark setup in relation to a single server and the Synology is the server with 2x 10GBe connections (with iSCSI offload) back to a switch, on separate VLANs, and 2x 1Gb connections into the same VLANs from the Synology. MSA P2000 G3 10GbE iSCSI disk storage performance stats I've found it's hard to come by numbers you can use when planning your storage system bandwidth, so I'm publishing stats for a modern 10GbE iSCSI array. Unlike Fibre Channel, iSCSI didn't need an HBA thanks in large part to the software based Microsoft iSCSI initiator. This Wiki will describe how to setup an Infiniband or iSCSI based SRP target on Ubuntu Lucid (10. Overhead from iSCSI itself is pretty much neglectable (except for very high IOP figures and very low actual bandwidth) and decent switches will be very close to the theoretical maximum. This section compares the performance of PVSCSI and LSI Logic with 10Gb SW iSCSI. Thats your limit getting out of the box. * Veeam VM runs here. Drobo makes award-winning data storage products for Small and Medium Businesses and Individual Professionals that provide an unprecedented combination of sophisticated data protection and management features, affordable capacity, and ease-of-use.
