Email & Collaboration Servers
Email downtime is immediately visible to every employee and every customer. ICD configures email-optimized servers with genuine, compatibility-verified components designed for 24/7 uptime — redundant power, ECC memory, RAID-protected storage, and remote management for 2 AM recovery.
On-premises email remains the choice for organizations that need full control over mailbox data — whether for regulatory compliance, data sovereignty, or legacy integrations. Microsoft Exchange Server 2019 is the dominant platform.
Email servers have a unique I/O profile: millions of small random reads and writes across thousands of mailbox databases simultaneously. They need rock-solid storage performance, enough memory to cache active mailboxes, and redundancy at every level.
