VMware vSphere High Availability (HA) is a cluster service that provides high availability for virtual machines (VMs) running in a cluster ¹ ². It is designed to minimize downtime and ensure rapid recovery from outages. Here are some key features and benefits of VMware vSphere HA - Failover protection: HA can detect hardware and guest operating system failures and automatically restart VMs on other hosts in the cluster. - Application availability: HA protects against application failure by continuously monitoring VMs and resetting them if a failure is detected. - Datastore accessibility: HA can restart affected VMs on other hosts that still have access to their datastores if there are any datastore accessibility failures. - Network isolation: HA can protect VMs against network isolation by restarting them if their host becomes isolated on the management or vSAN network. - Minimal configuration: HA requires minimal configuration and reduces hardware costs. - Increased application availability: HA provides increased application availability and integrates with DRS and vMotion. - Improved reliability: HA has multiple communication paths and eliminates external component dependencies to increase redundancy and reduce the likelihood of an external component outage disrupting HA operations.

Today, I am organizing a workshop in the AWS Dubai Summit around DDoS protection. One of the security controls that will be explored for managing application layer DDoS attacks is rate limiting. It’s a cheap, and fast protection layer, that reduces the impact of a large proportion of DDoS attacks in the wild. Here are 5 example rate limits, every online application could benefit from: ▶ blanket-rl: if (rate per IP > 5K per 1 min) then block ▶ endpoint1-specific-rl: if (URI = /login) && (rate per IP > 200 per 1 min) then challenge ▶ suspicious-ip-rl: if (IP is in suspicious-ip-list) then emit suspicious-ip-label; if (label = suspicious-ip-label) && (rate per label > 100 per 1 min) then block ▶ low-priority-countries-rl: if (IP is not in priority-country-list) then emit low-priority-countries-label; if (label = low-priority-countries-label) && (rate per label > 2000 per 1 min) then challenge ▶ ja3-rl: if (rate per ja3 > 10000 per 1 min) then challenge Got any questions about it? drop me a dm.

I have started to re-implement my physical HPE Proliant Servers Lab. In the next few days I will be creating a physical and virtual configuration of a specific use case of HPE StoreOnce VSA on Hyper-V and Eventually on vSphere. A Data Protection Storage Solution with Duplication and Replication. It can be implemented and integrated on the cloud as well, but I personally don't like very much such a solution, as a primary solution and backup flow. ... The primary objective is to showcase the configuration and the optimisation between the HPE StoreOnce VSA v4.3.9 and Commvault v11.80 backup software. ... The secondary objective would be in a few weeks I would create a specific "Alqubit | Technology Showcase" for our Backup Services and Solutions. ... If there is any possibility I will create a series of videos of Backup and StoreOnce Catalyst v4.4 OST integration and optimization with the major Enterprise Backups Software after Commvault, as a Veritas BackupExec v24 and NetBackup. The solution is similar to the integration of another excellent data protection storage solution of (ex) DataDomain with its Boost OST protocol and plug-in You can read or listen to the Alqubit | Blog article, about our backup and DR services: https://lnkd.in/dP46Qd-r #alqubit #ITservices #backupdesign

Configuring VMware storage involves several steps: 1. *Plan your storage infrastructure*: - Determine your storage needs (capacity, performance, redundancy) - Choose a storage protocol (FC, iSCSI, NFS, VMFS) - Decide on a storage architecture (direct-attached, SAN, NAS) 2. *Configure your storage array*: - Set up your storage array (e.g., SAN, NAS) according to the manufacturer's instructions - Create logical units (LUNs) for your VMFS datastores 3. *Create a VMFS datastore*: - Use the vSphere Client to create a new datastore - Select the storage array and LUN - Choose the VMFS version (e.g., VMFS-6) 4. *Configure datastore properties*: - Set the datastore name and description - Configure the block size and partition format - Enable or disable datastore features (e.g., thin provisioning, compression) 5. *Add storage to your ESXi host*: - Use the vSphere Client to add the storage array to your ESXi host - Configure the storage adapter settings (e.g., HBA, iSCSI initiator) 6. *Rescan for storage devices*: - Use the vSphere Client to rescan for new storage devices - Verify that your datastore is visible and accessible 7. *Configure storage policies*: - Create storage policies to define storage requirements (e.g., performance, redundancy) - Assign storage policies to your VMs 8. *Monitor and manage storage*: - Use vSphere tools (e.g., vCenter Server, esxtop) to monitor storage performance and capacity - Manage storage resources (e.g., thin provisioning, snapshot management) Some important considerations: - *Storage compatibility*: Ensure your storage array is compatible with VMware - *Storage performance*: Consider the storage performance requirements of your VMs - *Storage redundancy*: Plan for redundancy and high availability (e.g., RAID, clustering) - *Storage security*: Configure storage security features (e.g., authentication, encryption)
