If the availability of your network storage equipment is critical to your business, upgrade your Included service with an LenovoEMC service plan. For desktop network storage devices, select the Extended plan that will add 24x7 technical support and extend the warranty to 5 years. For rackmount network storage devices, select from Enhanced or Premium plans to best meet your business needs. When your IT resources are limited and availability is critical, both plans ensure 24x7 access to LenovoEMC's technical experts and next day onsite hardware service. The Premium plan adds 4 hour onsite service and includes a strategic spares kit to ensure your business keeps running. Decide the duration you need for your service plan and choose from 3 year or 5 year terms.
