Release Date:
02 Feb 2012
With virtualization’s ever-increasing adoption by small and medium size businesses (SMBs), and remote or branch offices (ROBOs), IT administrators face a major overhaul of the critical infrastructure that supports the expanding virtual environment.
In the data protection arena, while the environment will shift, the goal remains the same: to provide backup and restore capabilities to every server instance both as a whole, and as a file structure for individual recovery. The task then becomes choosing and implementing data protection for virtualized environments while maintaining interoperability and manageability with existing disaster recovery deployments.

HP X5000 G2 Network Storage System
System Ease-of-Use, High-Availability, Performance, and Interoperability Evaluation
Document number:
211130
Release Date:
06 Dec 2011
Today’s small and medium-size businesses (SMBs) have ever-growing needs with respect to storage. Not only do SMBs often need many terabytes of storage, they require a level of high-availability (HA) typically associated with large-scale, enterprise deployments. Furthermore, given IT staffing constraints, storage solutions should be easily installed and managed by existing IT staff.
Tests show that a 2-node, HP X5520 G2 9.6TB LFF 15K Network Storage System (hereafter X5000 G2) could be installed “out-of-the-box” to a fully-functional, HA system joined to a Microsoft domain in less than 90 minutes. The HP-supplied Initial Configuration Tasks tool guides the user through each deployment stage, eliminating a great deal of manual configuration.

Release Date:
05 Dec 2011
Small and medium size business (SMB) networks are facing increasing demands for data protection in their virtualized environments. As server consolidation continues, SMBs are unlikely to adhere to the level of redundancy sought by enterprise class datacenters. However, planning for the unexpected provides for a quick recovery in the event of an outage.
All SMBs can benefit from a flexible platform which can provide the desired backup, recovery, and replication features, while effortlessly integrating with their specific environment. A solution which can be implemented as a virtual or physical machine, on the LAN or SAN is preferable where storage may not be centralized, or additional servers may be hard to come by.

Tolly Group White Paper Series– Architecture in Action: Building SANs with Stacks
Document number:
206124
Release Date:
08 Aug 2006
QLogic commissioned The Tolly Group to build a microcosm of an SMB/Enterprise Fibre Channel environment to quantify critical elements related to scalability and management of competing SAN approaches, as well as to analyze the economic impact of each. This white paper provides a hands-on assessment of the scalability issues and the cost-of-ownership for the QLogic SANbox 5000 versus rival products that utilize a different architectural approach to SANs.
QLogic SANbox 5000 series “stackable” switches provide high-speed 10-Gigabit per second (Gbps) links dedicated to linking individual physical switches without reducing the number of ports available for use by end-user devices. In effect, this approach creates a virtual backplane bringing the performance advantages of the chassis approach to low-cost fixed-port switches. The white paper is based on two hands-on examinations conducted by The Tolly Group.
In the first part, The Tolly Group “built out” an actual SAN using two alternative offerings. The goal was to illustrate the configuration effort and to quantify hardware/software requirements associated with growing a SAN from an “entry” level connecting just two Fibre Channel devices through to a point where scores of devices could be connected.
In the second part of the study, engineer/analysts built and validated a cost model comparing the QLogic solution versus several leading “non-stackable” alternatives.

Maranti, Inc. CoreSTOR 2000 Network Storage Controller SAN Performance
Document number:
204143
Release Date:
19 Oct 2004
Maranti, Inc. commissioned The Tolly Group to evaluate its CoreSTOR 2000™ Network Storage Controller, a modular, high-performance network storage controller that delivers 8 to 16 ports across a 3U chassis. CoreSTOR 2000 delivers wire-speed storage virtualization and native CoreSTOR storage services to heterogeneous storage arrays and servers across all ports on the chassis. By supporting Gigabit Ethernet and Fibre Channel ports across the chassis, CoreSTOR 2000 provides connectivity between existing Fibre Channel and emerging iSCSI environments.
Tolly Group engineers measured the performance of the CoreSTOR 2000 in a simulated Exchange and SQL server environment and in three main areas: the I/O processing rate (I/O per second or IOPS), remote mirroring performance and high availability of the storage network controller when subjected to a number of scenarios.
Tests show that the Maranti CoreSTOR 2000 delivers consistent I/O processing performance; in fact, IOPS performance actually increases as the number of servers was ramped up from one, to four and then eight. Moreover, the CoreSTOR 2000 increased performance in most cases, as the number of local and remote mirrored storage subsystems increased. Interestingly, as loading increased on the CoreSTOR 2000, response times climbed as the number of servers increased, due to more I/O requests to the controller of the storage arrays. Response times decreased, however, as the number of storage subsystems increased because the requests were spread out to all available storage arrays via Maranti proprietary load-balancing scheme. Tests were conducted during August 2004.
