About this file
This document is Addendum #2 for the Forest Hills Public Schools Backup System Replacement Request for Proposal (RFP), issued by Plante Moran on 3/10/25. The addendum provides clarifications to potential vendors regarding two specific questions about the backup system replacement project. The scope of the project is focused on backup solutions for virtual machines (VMs), with approximately 120GB of SQL databases that will be backed up using application-aware settings.
The addendum addresses technical specifications, specifically allowing vendors flexibility in disk protection technologies. Vendors are permitted to use modern approaches like Erasure Coding instead of traditional RAID storage, provided they can meet the performance requirements outlined in the original RFP. The document notes that while Erasure Coding is acceptable, vendors should be aware of potential longer data write times due to increased computational requirements. The backup environment consists entirely of virtual machines, with no physical servers included in the backup scope.

Addendum #2
To: Interested Vendors
From: Dan Queck – Plante Moran
Date: 3/10/25
Re: Forest Hills Public Schools Backup System Replacement RFP
Please review the following questions and answers submitted for this RFP:
Question #1:
Can you provide an RVTools output of the VMWare environment or a breakdown of capacity by workload?
(i.e., in use space for VMs, SQL, physical servers, etc.) Different workloads deduplicate at different rates, so a breakdown aids the accuracy of sizing.
Answer #1:
The backup scope is for VMs only, so there are no physical servers to back up. While there are approximately 120GB of SQL databases across a few servers, these are backed up with application-aware settings turned on. We recommend sizing with an average deduplication rate for all workloads, keeping in mind that the actual deduplication rate may vary somewhat.
Question #2:
Are vendors allowed to use a more modern approach to disk protection with Erasure Coding, or is RAID storage required?
Answer #2:
A more modern approach to disk protection, such as Erasure Coding, can be used as long as the performance requirements outlined in the RFP can be met. It is important to consider the potential for longer data write times due to the increased computational requirements of Erasure Coding.
