Rymvard released version 0.23 on October 4, 2026, adding SAP HANA host-memory accounting, placement proposals and replication takeover checks to its data center capacity ledger. The company tested the early-access software on a simulated landscape; it has not provided customer deployment results or announced general availability.
Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting, placement proposals and replication takeover checks to its data center capacity ledger, as detailed in the original analysis. The early-access software is aimed at SAP hosting providers and operations teams, but the company’s reported test results came from a simulated estate, not a customer deployment.
The release breaks each HANA host’s physical memory into categories: an operating-system reserve, memory used by HANA systems, allocated but unused memory, capacity reserved for replicas from other sites, and remaining free memory. Rymvard’s default operating-system reserve is 10% of the first 64 GiB and 3% of memory beyond that, unless a host has a different reserve configured. System usage is based on its 30-day peak. When allocations exceed physical memory, the ledger reports overbooking rather than presenting an artificially negative free-memory figure.
For systems using HANA System Replication, the software checks whether the secondary host could take over the primary system’s allocation. Results are reported as fits, fits after stopping named systems, does not fit with a shortfall in GiB, or unknown. A production system belonging to another customer is not treated as stoppable; named test or development systems may be. A replication status older than one hour, or a memory reading older than 24 hours, produces an unknown result rather than a pass. Scale-out systems are evaluated as a whole using the weakest host pair.
Version 0.23 also proposes a host and replication-site partner for a new HANA system and estimates memory runway by site and quarter, using planned go-lives weighted by probability. Rymvard says HANA instances are mirrored into its compute view for customer showback and lifecycle planning. Its new SAP Operations workspace highlights free HANA memory, production systems without replication, takeovers that would fail, and hosts above 90% utilization.

Making HANA Failover Capacity Visible
The release addresses a specific planning problem for providers: a data center may have space in its wider infrastructure while an individual HANA host or replication partner lacks the memory needed for a deployment or takeover. Showing overbooking and takeover shortfalls separately can help operations teams identify those constraints while planning placements, rather than assuming that overall facility capacity means every workload can be accommodated.
The checks may also help teams compare proposed deployments with site-level capacity and identify failover exposure. Their practical value, however, depends on the accuracy and freshness of the information feeding the ledger. Rymvard’s rule that stale readings produce an unknown result avoids treating old measurements as evidence of available capacity. The release does not establish that the product reduces costs, improves reliability or has delivered measurable customer outcomes.

Read-Only SAP Data Connections
Rymvard says its collector connects to the SAP Host Agent over HTTPS and permits four read operations: ListInstances, ListDatabases, GetDatabaseStatus and GetComputerSystem. A separate monitoring connection uses TLS and a fixed set of six SELECT queries, with a 60-second limit per system and no more than eight systems queried at once. The company says the software does not write to SAP.
The release also lists read-only information sources for system, customer and environment details: SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. Rymvard reports testing on a simulated landscape with 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, it identified one production system without replication, a takeover short by 512 GiB, a host overbooked by 128 GiB, and a replication in an error state. The company says the displayed screens use an illustrative estate and do not represent a real customer, site or outcome.
“Nothing is ever written to SAP.”

Customer Results Remain Unreported
Rymvard describes version 0.23 as early-access software and has not identified a customer deployment or supplied customer outcomes for the release. The simulated test results show how the stated checks behaved in that scenario, but do not establish performance across live customer landscapes, unusual SAP configurations or workloads that change over time. No independent evaluation is included in the supplied release information.
The company has not announced a general-availability date or published prices, saying terms are arranged with early-access partners. Details are also limited on how integrations are validated in individual environments and how frequently capacity readings refresh beyond the stated age thresholds. The release describes the product’s rules and limits, but does not resolve how it performs in every operating environment.

Early-Access Partner Evaluations
The next step is evaluation by early-access partners, with pricing arranged directly with Rymvard. The company has not named a participating customer or announced a broader release date. Evidence from live deployments, including how the ledger handles real estate configurations and changing capacity data, would provide a clearer basis for judging the tool’s operational value.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA host-memory accounting, placement proposals, replication takeover checks and a SAP Operations workspace to its data center capacity ledger.
Was the software tested at a customer site?
Rymvard says its reported test used a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. The company has not provided customer deployment results for this release.
Does Rymvard write data to SAP?
The company says its SAP connections are read-only and states, “Nothing is ever written to SAP.”
When does a replication takeover check return unknown?
According to Rymvard, a replication status more than one hour old, or a memory reading more than 24 hours old, results in an unknown status rather than a passing result.
When will the product become generally available?
Rymvard has not announced a general-availability date. The software is in early access, with evaluation and pricing arranged directly with partners.
