01 · What it is

ThinkSystem Storage, made clear.

Lenovo's storage covers the mid range with two families: the DEs — pure block SAN, fast and no-frills, the price/performance hard to beat — and the DMs with NetApp ONTAP technology: unified (block+file), efficient snapshots, replication and tiering. The pragmatic choice for those who want solidity without paying for the superfluous.

02 · How to use it well

The things that make the difference.

The two families

VMs, databases, file sharesthe data's consumers
DE · pure block
DM · unified ONTAP
simple and fast · rich in services
Snapshots & replicasthe protection in the design
The mid range, servedwithout paying for the excess
The right storage, not the maximum

The family for the case

Block only for the clusters? DE. File and replication? DM: the choice on the requirements, not on the catalog.

Snapshots with policies

The data's first line of defense: planned, retained, tested.

Replication between sites

The DM replicating toward its twin: the storage's DR at a mid-range cost.

Multipath and resilience

Dual controllers and redundant paths: the SAN that withstands the single fault, verified.

ThinkSystem DG/DM: unified, NVMe and hybrid

The ThinkSystem storage covers the cases: the DMs (with ONTAP inside) do unified block+file with snapshots, replication and tiering to the cloud, the DG all-flash QLC push the flash's price/GB onto the capacity tier, the DEs are the simple, fast block for the careful budgets; the enterprise functions (dedupe, compression, encryption, synchronous replication) are there where needed, the management is familiar and the VMware/Veeam integration is certified.

  • DM / ONTAP — unified with snapshots and SnapMirror: the data replicated and tiered
  • DG QLC — all-flash at the disk's price: the capacity tier that runs
  • DE — the essential block: a simple SAN, the right price
  • Data reduction — dedupe+compression: the TB bought only once
  • Replica sincrona — RPO 0 between rooms where the metro cluster is needed
  • Certificazioni — VMware, Veeam, SAP: the integration without surprises
04 · Numbers and lifecycle

The numbers that matter.

RPO 0

QLC
capacity flash: the all-flash TCO changes

5 anni

Storage is chosen by data profile: block, file, performance and budget — the right model we identify.
05 · Use cases

Where it really pays off.

Storage for clusters

The SAN under vSphere/Hyper-V, sized right.

File services

The corporate shares on serious iron.

An affordable refresh

The old array replaced without a bloodletting.

Not everyone needs the million-euro storage: DE and DM do the job — chosen and managed with judgment.
