Infrastructure Requirements - Server - ESTIMATION
These specifications are also indicated in the conditions of use of the ESTIMATION software
** The minimum server configuration is for small installations, i.e. those used to count small bids, with few estimators at a time, and with a small database.
Configuration - server :
Minimal**
32 or 64 bits operating system: Windows Server 2012 R2 or higher (or windows 8.1);
1 Dual Core processor of 2.5 GHz at 75% of its free power;
4 GB of free memory;
SSD hard drive or equivalent in performance;
RAID 1, 5, 6, 10, 50 or any other RAID configuration that ensures data redundancy and can survive the loss of a disk;
Daily external office backup system for data security;
70 Gig or 30 Gig after Windows and SQL server installation;
100 MBIT network;
The server shall be constantly functional even at night unless properly shut down for maintenance;
The server should be equipped with a UPS battery backup to avoid data loss.
Virtualization
The SQL ESTIMATION instance can be virtualized under the following conditions:
VMWare ESX 6.5 tested and compatible OR Microsoft Hyper-V (no guarantee for other virtualization technologies);
1 x 2.5 GHz dual-core processor 100% dedicated to the SQL ESTIMATION instance;
4 GB of physical memory 100% dedicated to the SQL ESTIMATION instance;
Disk system(s) 100% dedicated, or very little used by other virtual machines.
Recommended
32 or 64-bit operating system: Windows Server 2016, Windows Server 2019 ;
3 Ghz 4-core processor at 75% of its free power;
8 GB of free memory;
SSD hard drive or equivalent in performance;
RAID 10 disk system(s) with 4 disks of 10 000 rpm or more for data redundancy
Ideally: Disks should not be shared with other application(s) that require a lot of disk access;
External daily backup system at the office for data security;
100 Gig or 50 gig after Windows and server installation;
1 GBIT network;
The server shall be constantly functional even at night unless properly shut down for maintenance;
The server shall be equipped with a UPS battery backup to prevent data loss.
It is not recommended to install SQL Server on a controller domain. It is not supported by Microsoft.
Virtualization
The SQL ESTIMATION instance can be virtualized under the following conditions:
VMWare ESX 6.5 tested and compatible OR Microsoft Hyper-V (no guarantee for other virtualization technologies);
Processor: 2 cores of 3 Ghz dedicated to the SQL ESTIMATION instance;
8 GB of physical memory 100% dedicated to the SQL ESTIMATION instance (For a SQL Server Express instance, 4 GB is sufficient);
Disk system(s) 100% dedicated, or very little used by other virtual machines.
Optimal
32 or 64-bit operating system: Windows Server 2016, Windows Server 2019;
SQL Server 2016 Standard;
The collation must be "Latin1_General_CI_AS" (to know the collation: SELECT SERVERPROPERTY('collation') or SELECT CONVERT (varchar, SERVERPROPERTY('collation')); ) or EXECUTE sp_helpsort;
We recommend a SQL Server Standard license for large installations as the Free Express is limited to 1.4 GB memory and 4 cores

6-core 3.5 GHz dedicated processor;
8 GB of free memory;
SSD hard drive or equivalent in performance;
RAID 10 disk system with 4 dedicated 15,000 rpm disks for data redundancy;
The external daily backup system at the office for data security;
100 Gig or 50 Gig after Windows and SQL server installation;
1 GBIT network;
The server should be constantly functional even at night unless properly shut down for maintenance;
The server should be equipped with a UPS battery backup to prevent data loss.
Virtualization
The SQL ESTIMATION instance can be virtualized under the following conditions:
VMWare ESX 6.5 tested and compatible OR Microsoft Hyper-V (no guarantee for other virtualization technologies);
Processor: 6 cores of 3.5 GHz dedicated to the SQL ESTIMATION instance;
8 GB of memory 100% dedicated to the SQL ESTIMATION instance;
Disk system(s) 100% dedicated, or very little used by other virtual machines.
The customer is entirely responsible for the security of his data and the redundancy of his servers
Internet connection
The server must have a high-speed internet connection;
In the event that your staff and our ConstructBuy representatives need to work on your database simultaneously:
We recommend 1 Terminal Server access to ESTIMATION for our employees at your service;
It is also possible to connect with Screen Connect;
The upload speed of your internet connection should be at least 5 MBIT, and ideally 10 MBIT or more.
