You didn't specify the 3750 model, if it's the X, then there is a configuration guide for it on the Rapid Configuration Portal: Go to this link, review the Configuration Guide (network setup info), and then click the Rapid EqualLogic Configuration Portal, link, on that page is the configuration for the 3750X and ESX settings. Also, you want to configure all your ESX hosts per this best practices document: en.community.dell.com/.../20434601.aspx Also, you should setup a system running the SANHQ to help get a better understanding of your performance.  This can help support if after reviewing these documents you can't get the performance expected. -joe
Good morning, I'm looking for input about how our setup might be better arranged. Overall, the best throughput we can get is 30-40MB/s tops. Higher IO operations such as roaming profiles take an extraordinary amount of time. We're using Citrix XenDesktop 7 with only 80 total desktops, often 50 are in use on an average day. We have the normal assortment of other servers: Exchange, SQL, AD, file storage. I'm starting to think it may be something with our setup. The hardware: 4 Dell R810s, the 4 builtin NICs are used for iSCSI, an addin PCIe card for two 10Gb ethernet ports for ESXi 5.1 traffic. ESXi has the iSCSI set to 9000bytes at the switch and port level. 1 EqualLogic PS6000xv (16x 600GB 15k rpm hard drives, controller is 4 ports all set to iSCSI traffic, no dedicated management port) 1 EqualLogic PS6100E (24x 2TB 7200rpm hard drives, controller has 4 iSCSI ports and 1 dedicated management port) These two SANs are configured as a load balanced group. Jumbo frames of 9000 bytes is enabled. The SANs are connected to our core stack of 2 Cisco 3750s. All iSCSI ports are vlan'd together. Jumbo Frames of 9000 bytes are set. The ESX hosts are connected to a Cisco Nexus 5010. Two 10Gb interfaces link the Nexus to the 3750s.  Everything is running the latest firmwares. Is this an optimal setup? Would splitting the arrays be the better option? Am I missing something else entirely? I would appreciate any input. Thanks. -March
SAN network seems slow
