Hitachi Maintenance Contracts

We know what it’s like being stuck between two maintenance plans, and being forced to pay more. We understand that every one of our customers has their own needs that must be met, when choosing a cost-effective maintenance plan for your Hitachi storage system. That’s why ISC doesn’t lump all of our customers into a cut and dry maintenance plan. We allow you to pick each individual service that your company needs, without forcing you to pay for extra “must have” add-ons  that you don’t need.

We can offer any hour/day maintenance contract for your Hitachi storage device. From 5×9, to 24×7, ISC Group has you covered. Our far reaching Hitachi support resources give us the ability to offer you such flexible, and customized maintenance plans. 


Post Warranty Hitachi Storage SLA Options

We offer several types of post-warranty HITACHI SLA options (Service Level Agreements) depending on your current hardware configuration, support and maintenance needs. Choose any SLA that works best for your company:

  • 7x24x4 (7 days a week, 24 hours a day, same day, 4-hour response time)
  • 5x9x4 (5 days a week, 9 hours a day, same day, 4-hour response time)
  • NBD (next business day)
  • Customized SLA to meet your unique requirements


 Hitachi Contract Options

We know being able to extend the life cycle of your Hitachi disk array, has a direct effect on your bottom line. That’s why we offer several types of maintenance contract options to match your unique Hitachi support needs, and budget requirements:

  • Data storage full support agreements: When you need scheduled and remedial maintenance, replacement parts, technical phone support and a dedicated on-site Hitachi field engineer.​
  • Data storage shared support agreements: When you already have local field engineers, or technical personnel and simply need scheduled and remedial Hitachi maintenance, replacement parts and technical phone support.

When the manufacturer’s warranty expires for your Hitachi disk array or storage device, post-

Post-Warranty maintenance agreements are usually the most economical, and practical solution to maintaining the health of your Hitachi storage equipment. That’s one of the many reasons why ISC Group makes sure to offer flexible maintenance contracts to meet data storage needs.


Need Your HITACHI Storage Device Repaired On-site?

ISC Group specializes in getting a field engineer on-site fast, for repairs and service of your Hitachi Storage Device. In order to minimize any downtime that your storage system may incur, we make sure to offer our on-site Hitachi maintenance services 24 hours per day, 7 days per week.

We understand that for a variety of reasons your Hitachi storage device may not be covered under a maintenance contract, even though it will require service at some point during its lifetime. This doesn’t cause any issues with us. With or without coverage from a maintenance contract, our field service engineers can still provide a wide range of Hitachi technical support and on-site maintenance services for a set hourly rate.

For your convenience, No Hitachi Maintenance contract is required to take advantage of our services.  We will only bill you for time and materials, no extra service fees.
