EqualLogic Outperforms Competitive SANs under Heavily Virtualized Exchange 2010 Workloads

The claims of storage vendors vary widely, and this is certainly the case among iSCSI vendors, where architectures and capabilities can be very different. Dell has long claimed that the EqualLogic storage family leverages tried and true internal capabilities to deliver distinctly better ease of use and performance without requiring convoluted or time-consuming configuration efforts.  And, they claim, they’ve integrated these proven capabilities into a comprehensive storage infrastructure—based on their elastic pool technology—that also delivers more scalability than their competitors. With these claims in mind, Taneja Group set out to examine Dell’s differentiation in the midst of a crowded and rapidly growing field. To do this, we performed hands-on validation of a Dell EqualLogic PS Series iSCSI SAN array against a leading competitive iSCSI array and a second leading Fibre Channel array.

Evaluating the ESX4 Hypervisor and VM Density Advantage

In this Technology Validation, Taneja Group reviews the effective performance of VMware ESX 4, Hyper-V R2 (RC) and XenServer 5.5 hypervisors.  Based on our hands-on testing, VMware's ESX4 hypervisor continues to carry a marked advantage in VM density - the number of guest VMs a hypervisor can effectively host - versus the competition.  Our conclusion, VMware has a VM density advantage of 1.8:1 versus the competition, or can effectively virtualize 80% more guests, even under what we think are conditions representing aggressive workloads.  As we've reviewed before, this advantage translates into a lower total cost of acquisition for the VMware virtual infrastructure, making VMware as much as 5% to 29% cheaper than the competition.

The True Cost of Server Virtualization Solutions

In this Technology Validation, Taneja Group reviews the effective performance of the Hyper-V and ESXi hypervisors.  Based on their performance, we then review the total cost of acquiring Microsoft Hyper-V plus System Center and VMware Infrastructure 3.  Based on our findings, VMware wins, with a cheaper cost of acquisition that flies in the face of common misperceptions.  VMware has an effective VM density at least 1.5:1 times greater than Microsoft Hyper-V, and comes out ahead in purchase cost by 5% to 29% when compared to Microsoft.

Brocade FME - Total Enterprise File Management

In March of 2008, Brocade introduced the Brocade FME, an in-band file virtualization appliance to complement the global namespace, network file management, and wide area file system technologies already in their portfolio.  Taneja Group took a detailed hands-on look at the Brocade FME with a Technology Validation that put the FME through its paces while virtualizing and moving open CIFS files.

NAS Tiering and Migration with NeoPath - Testing and Validation Report

In the past 12 months, enterprise NAS users have become very aware of the beneficial impact that storage tiers and intelligent migration can have on their data center.  Based on our conversations, we find that most IT executives can now readily list the benefits of storage tiers: increased utilization rates, lower costs of ownership, online disk archiving, and streamlined data protection processes.
