Micron is launching a 7500 datacenter SSD utilizing 232-layer 3D NAND expertise, exceeding the prior 7450 drive on all counts besides random write IOPS the place each drives are equal.
The 176-layer 7450 with a PCI gen 4 interface was launched in March 2022 as a successor to the 7400 and its 96-layer 3D NAND. It got here in U3, E1.S, and M.2 codecs, whereas the 7500 is solely obtainable within the U.3 format. Micron is focusing constantly on dependable low latencies with the 7450 delivering sub-2ms latency and the 7500 bettering that.
Alvaro Toledo, VP and GM of Micron’s Knowledge Middle Storage group, stated: “We’ve got achieved a breakthrough in latency, enabling response occasions under 1ms for 6x9s QoS in mainstream drives. This implies our prospects can run their data-intensive workloads sooner, extra effectively and with extra predictability than ever earlier than.”
In comparison with the 7450, the 7500 has sooner sequential learn and write bandwidth and random learn IOPS. Speeds in our desk are “as much as” speeds and differ with capability.
The 7500 has broad help for the Open Compute Venture (OCP) SSD 2.0 specification, which gives clever administration, efficiency optimization, seamless integration, and error dealing with for datacenter environments.
Micron supplied charts displaying how the 7500’s efficiency compares with different suppliers’ drives in the identical market class:
We perceive the competing drives could also be Solidigm’s DC P5430 (crimson line), an SK hynix SSD (mild gray) and a Kioxia drive (darkish gray). The chart reveals the 7500 being equal to Kioxia’s drive however ultimately beating it, whereas it’s at all times sooner than the SK hynix drive and a lot better than Solidigm’s SSD. That’s not stunning as Solidigm’s gadget makes use of QLC NAND, not TLC as all of the others do.
A RocksDB aggressive comparability reveals the 7500 having higher efficiency once more:
The sunshine gray and darkish gray strains signify the identical opponents as above.
Micron has outfitted the 7500 with many safety features:
- Administrative instructions to permit standardized management over features equivalent to namespaces and safety, which simply combine with OCP-compliant administration methods.
- Latency monitoring to enhance efficiency by enabling the monitoring and analysis of latency points reported by way of the storage stack.
- Error restoration and error injection options to allow speedy restoration of the drive and simulation of errors generally encountered in servers.
- Self-encrypting drive (SED) choices with AES-256 hardware-based knowledge encryption, operating at line charge, SHA-512 and RSA to maintain knowledge protected.
- Safe Encrypted Setting (SEE) to supply devoted safety processing {hardware} with bodily isolation for improved safety.
- SPDM 1.2 attestation verifies gadget identification and firmware integrity to validate belief within the SSD from manufacturing by way of deployment.
- Choices for FIPS 140-3 Degree 2 and TAA compliance to satisfy U.S. federal authorities procurement necessities.
The 7500 is accessible now by way of Micron’s OEMs and channel companions. Take a look at a product transient right here.
