CAI-NVES3T8K1V 개요
An enterprise NVMe SSD is a data storage device that connects directly to the host CPU over the PCI Express bus using the NVM Express protocol, eliminating the SATA/SAS controller bottleneck of legacy drives. Within the storage hierarchy, an SSD is a non-volatile storage medium built on NAND flash; NVMe SSDs form the top tier of server storage performance, sitting above SAS and SATA SSDs, and are a core building block of modern power management and compute subsystems in rack-scale servers.
Key features of the CAI-NVES3T8K1V include 3.80 TB of usable capacity, a PCIe 4.0 x4 NVMe interface for high-speed data transfer, and the E1.S 15 mm form factor (EDSFF standard) that enables high-density front-panel drive bays. The KIOXIA XD7P classification as High Performance, Medium Endurance makes it suitable for mixed read/write workloads that demand both throughput and a meaningful drive-writes-per-day rating.
Technically, the drive uses the KIOXIA XD7P Series platform with PCIe Gen4 signalling, delivering substantially higher queue depth, lower latency, and higher IOPS than SATA alternatives. The Gen4 interface doubles the theoretical bandwidth of PCIe 3.0, benefiting AI training data pipelines, database logs, and virtualization I/O.
Typical applications include the Cisco UCS C845A M8 AI Server, where the drive serves as local NVMe scratch or data-tier storage for Generative AI fine-tuning and inference workloads, as well as general rack-server boot and data storage in Cisco UCS C-Series systems.
Design consideration: this is a Cisco-qualified OEM drive intended for UCS servers; verify controller and firmware compatibility before deploying in third-party platforms, and confirm chassis bay support for the 15 mm E1.S variant rather than the 9.5 mm version.

일반적인 애플리케이션
CAI-NVES3T8K1V 적합 용도: 6 애플리케이션s: AI Server Local NVMe Storage, Database and Analytics Storage, Virtualization and VDI Hosts, High-Density Edge Storage, Media and Streaming Caching, Enterprise Boot and Scratch Storage.
AI Server Local NVMe Storage
The CAI-NVES3T8K1V is qualified for the Cisco UCS C845A M8 AI Server, a NVIDIA MGX-based system supporting two to eight AMD or NVIDIA PCIe GPUs for Generative AI fine-tuning and inference. In this role the drive provides the local data-tier storage that feeds training datasets to GPU memory. Its PCIe 4.0 NVMe interface doubles the bandwidth of Gen3 SSDs, reducing dataset staging time between storage and GPU workers, while the KIOXIA XD7P medium-endurance classification tolerates the repeated read/write cycles of checkpointing and dataset shuffling. A single 3.8 TB module per E1.S 15 mm bay lets administrators scale local capacity linearly with bay count, keeping AI pipelines saturated without a SAN hop.
추천
Database and Analytics Storage
Enterprise databases benefit directly from the CAI-NVES3T8K1V's combination of PCIe 4.0 NVMe low latency and the XD7P medium-endurance write profile. Transaction log writes, index rebuilds, and temp-table workloads punish read-optimized drives, whereas the High Performance, Medium Endurance XD7P classification is designed for mixed workloads with meaningful drive-writes-per-day headroom. Deployed in Cisco UCS C-Series rack servers, the E1.S 15 mm form factor packs multiple 3.8 TB modules into front-panel bays for high-capacity, low-latency local storage. Compared with SATA SSDs, NVMe's deep queue submission model sustains far higher IOPS under concurrent OLTP threads, cutting p99 query latency in analytics dashboards.
추천
Virtualization and VDI Hosts
Virtual desktop and VM consolidation workloads generate highly randomized I/O from dozens or hundreds of concurrent guests. The CAI-NVES3T8K1V's NVMe 4.0 interface sustains this random traffic with queue depths that SATA SSDs cannot match, making it a strong fit for UCS C845A M8 and other C-Series hosts acting as dense virtualization nodes. The 3.8 TB capacity per drive balances VM density against bay count, and the medium-endurance XD7P flash tolerates steady write amplification from guest OS paging and snapshot operations. Its E1.S 15 mm hot-swap form factor also simplifies maintenance windows, since failed drives can be replaced from the front panel without host downtime.
추천
High-Density Edge Storage
Edge and colocation deployments value storage density per rack unit, and the E1.S (EDSFF) form factor was created for exactly this purpose. At 15 mm thickness, the CAI-NVES3T8K1V delivers 3.8 TB in a drive substantially smaller than a 2.5-inch U.2 SSD, letting 1U and 2U UCS systems carry far more local capacity. The PCIe 4.0 link provides full Gen4 bandwidth to each module, important for edge analytics and content delivery caches where ingest throughput is limited by local storage, not WAN. The XD7P platform's enterprise power-loss protection and thermal design support the continuous-duty operation expected in lights-out edge facilities.
추천
Media and Streaming Caching
Streaming platforms and content delivery origins demand high sequential read throughput with bursty write ingest. The CAI-NVES3T8K1V's PCIe 4.0 NVMe interface provides the multi-GB/s sequential bandwidth needed to serve many concurrent 4K streams from local storage, while its 3.8 TB capacity holds substantial content caches per module. The XD7P medium-endurance classification absorbs cache eviction writes that would prematurely wear read-intensive drives. In UCS C845A M8 or C-Series media nodes, multiple E1.S 15 mm modules can be striped for additional throughput, and hot-swap capability allows cache capacity to be expanded without server downtime during traffic peaks.
추천
Enterprise Boot and Scratch Storage
Beyond data-tier duties, the CAI-NVES3T8K1V serves as high-reliability boot storage and scratch space for compute-intensive UCS servers. NVMe boot reduces OS and application load times compared with SATA boot drives, and the enterprise XD7P platform includes power-loss protection that guards filesystem integrity during unexpected shutdowns - a frequent failure point for consumer SSDs in servers. As scratch disk for rendering, simulation, or HPC jobs, its Gen4 interface keeps intermediate file I/O from bottlenecking CPU and GPU workers. The 3.8 TB size is large enough to host OS, applications, and sizeable working sets on a single module per server node.

설계 노트
Form-factor confusion is the most frequent ordering error for this SKU. The CAI-NVES3T8K1V is E1.S 15 mm; some XD7P capacity points (e.g., the 1.9 TB listed at CDW) use E1.S 9.5 mm. A 15 mm module will not seat in a 9.5 mm bay. Verify your chassis (UCS C845A M8 or third-party) provides 15 mm E1.S bays before purchase, and note the drive is marked non-cancellable by at least one distributor (DirectDial).
Lifecycle planning: eol.network reports Cisco end of sale for the CAI-NVES3T8K1V= on 2026-12-25. After that date, new units come only from residual channel stock or Cisco spares. If your deployment roadmap extends into 2027, either secure stock now or plan the migration path to the replacement Cisco NVMe SKU. Distributor stock is already uneven (Howard shows out of stock; 4networks lists backorder with contact-for-lead-time).
Thermal design: E1.S drives in high-density bays rely on chassis-directed airflow and the server's drive-carrier thermal interface. In UCS C845A M8 systems, ensure blanking panels are installed in unused bays so airflow over populated NVMe modules matches Cisco's validated thermal profile, sustaining Gen4 performance without thermal throttling under sustained AI workloads.
