Mechanical Architecture & Environmental Resil...
The HCI-SD38T6I1X-EV= is a 38TB Self-Encrypting Drive (SED) designed for Cisco HyperFlex HX240c-M5 nodes, specifically engineered for high-density cold data storage in enterprise HCI environments. Based on Cisco’s HyperFlex 4.5 architecture documentation, this 3.5″ Nearline SAS 12Gbps drive combines 256-bit AES hardware encryption with 10K RPM performance, achieving 25% higher sequential read throughput than standard 7.2K RPM HDDs while maintaining FIPS 140-2 Level 2 compliance.
Key specifications include:
When deployed in HX240c-M5L hybrid nodes, the HCI-SD38T6I1X-EV= operates in conjunction with NVMe Optane caching layers (e.g., HX-NVME380GM7=):
No. The drive requires:
Metric | HCI-SD38T6I1X-EV= | HCI-SD18T6I1X-EV= |
---|---|---|
Areal Density | 2.1 Tb/in² | 1.8 Tb/in² |
Idle Power Consumption | 5.8W | 4.2W |
Max Concurrent Encryption | 32 sessions | 16 sessions |
RAID 6 Rebuild Time | 14.8 hours | 6.2 hours |
For guaranteed compatibility with HyperFlex cold storage tiers, HCI-SD38T6I1X-EV= is available through certified channels like itmall.sale. Validate configurations using:
The HCI-SD38T6I1X-EV= demonstrates Cisco’s strategic focus on cost-optimized archival storage in hyperconverged environments. While its 260MB/s throughput seems modest compared to 3.5GB/s NVMe counterparts, the drive’s 550TB/year workload rating makes it ideal for healthcare PACS systems or financial transaction logs requiring long-term retention. However, enterprises must carefully evaluate encryption key management workflows – improper key rotation in multi-petabyte clusters can lead to catastrophic data inaccessibility during drive replacements. Always perform quarterly cryptographic erase drills using Cisco’s HX Secure Erase Utility to validate disaster recovery protocols.
