Abstract from the Dell white paper:

This white paper provides an introduction to the Isilon SmartFlash, the foundation of the Isilon flash-based caching performance feature. The paper includes an overview of the OneFS caching architecture and describes the benefits of a SSD-based caching solution.

Announcing EMC Isilon OneFS 8.0.1 from Dell

Blog posting from Risa Galant

New Features and enhancements in OneFS 8.0.1The following are just some of the new features included in OneFS 8.0.1. For details and the complete list of new features and enhancements, see the OneFS 8.0.1 Release Notes. You’ll need to log in to EMC Online Support to access release notes.Security enhancementsCloudPools proxy support means that you can configure CloudPools to route data coming from or going to a public cloud provider through a proxy server. CloudPools works with proxy servers running the SOCKS v4, SOCKS v5, or HTTP protocol. Note that SOCKS v4 does not support authentication.SyncIQ now supports failover and failback of SmartLock compliance mode domains containing protected WORM (write-once-read-many) files. After successful replication and failover, you can continue to work in SmartLock compliance mode domains on the target cluster, adding new files and committing them to a WORM state. When failing back to the original cluster, SyncIQ ensures that WORM files are appropriately replicated back to the SmartLock compliance mode domain.Several new CLI commands were added to support using Transport Layer Security (TLS) certificates to enhance communication security over a network.

SmartQuotas Performance from trimbn

There have been a couple of recent questions from the field regarding quota performance. So it seemed like an ideal opportunity for a blog post on one of the more obscure tuning parameters of Isilon SmartQuotas.

Within OneFS, quota data is maintained in Quota Accounting Blocks (QABs). Each QAB contains a large number of Quota Accounting records, which need to be updated whenever a particular user adds or removes data from an area of the filesystem on which quotas are enabled (quota domain).  If a large quantity of clients are simultaneously accessing the quota domain, these blocks can become highly contended and a potential bottleneck. Similarly, if a single client (or small number of clients) consistently makes a large number of small writes to files within a single quota, write performance could again be impacted.

To address this, as of OneFS 7.2.1.1 and later, quota accounts have a mechanism to help avoid hot spots on the nodes storing QABs. Quota Account Constituents (QACs) help parallelize the quota accounting by including additional QAB mirrors distributed across other nodes in the cluster.

The New Way

If you’re looking for a very modern way to check and monitor performance, you should give Performance Analyzer a try

Monitor and Analyze your EMC Isilon storage systems configuration and performance metrics. Correlate events and metrics from your Storage system, the underlying operating system and the related infrastructure components (VMware vSphere Datastores aso.). Troubleshoot issues using our preconfigured, efficient dashboards.

Instantly detect when Nodes are down or not healthy. Find performance bottlenecks, storage protocol issues and slow response times in a heartbeat.

Dell EMC Isilon

Some of our EMC Isilon integration features are:

  • Monitor metrics across multiple systems
  • Check caching efficiency and open files in real time
  • Full insights into Latency and IOps
  • Details based on Protocol
  • React on front-end and backend-network anomalies
  • Drilldown to Details, Cluster Overview to single Disk

Combine with our vSphere Analyzer, Operating System or Database Collector to get all insights!

Use Case - Tamper-resistant Clinical Trials

Goal:

Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).

Implementation:

immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance

Goal:

Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.

Implementation:

While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace

Goal:

No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


Implementation:

immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data

Goal:

IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.

Implementation:

immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence

Goal:

CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.

Implementation:

As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
