Cost-effective storage solutions
Reliable, transactionally consistant data
High availabilty architecture
Bringing Storage Area Networks (SANs) to the Remote and Branch Office (ROBO)
Until recently, networked storage environments and all the benefits that they bring were exclusive to large enterprises. The introduction of iSCSI in the past few years saw the small-to-medium business (SMB) market rapidly adopting SAN technology that was previously too costly and complex to implement. Yet ROBOs are still having a hard time justifying what remains to be a significant investment.
The FalconStor® NSS Virtual Appliance delivers an easy-to-build, cost-effective storage solution that allows ROBO users to reap the benefits of storage virtualization. A virtualized storage environment provides makes it easier to manage and scale storage, while optimizing data protection and availability.

Why Virtual Servers Need Virtual SANs
VMware server virtualization is very attractive for SMB and ROBO environments, but it demands a highly available infrastructure. Advanced VMware features such as VMware High Availability, VMotion, and VMware Distributed Resource Scheduler require shared storage in order to function.
The need to deploy shared storage has limited SMB and ROBO adoption of server virtualization because of the cost and complexity involved in building a SAN, even a small one. This has also limited their disaster recovery (DR) options.
The FalconStor® NSS Virtual Appliance removes all these barriers to server virtualization. For example, to ensure high availability (HA), FalconStor NSS Virtual Appliance can be deployed on two VMware ESX servers that can share storage with each other as well as additional VMware ESX servers. In this model, each FalconStor NSS Virtual Appliance maintains mirrored data from the other server. If one of the servers is lost, all virtual machines that were running on the failed server can restart using the storage resources of the remaining server. Downtime is kept to a minimum and applications are quickly back online.

Enterprise-Class Data Protection
The FalconStor® NSS Virtual Appliance provides numerous enterprise-class data protection features, including application-aware, space saving snapshot technology can maintain up to 64 point-in-time copies of each volume. This provides:
- Quick recovery of deleted or corrupted data
- 100% transactionally consistent instant copies of application data for testing, development, auditing, reporting, etc.
- A source for VMware Consolidated Backup with limited impact to VMware ESX production servers

WAN-optimized data replication is also included. An ideal ROBO solution, FalconStor NSS Virtual Appliance minimizes bandwidth utilization of data replication by sending only unique data blocks over the wire. Built-in compression and encryption mean that no other specialized network devices are needed to connect remote locations with the data center or DR site. Tape backup for multiple remote offices can be consolidated to a central site, eliminating the need for distributed tape autoloaders and the management headaches associated with them.
