  🌐 #Zenith of #Enterprise #Storage in #ProxmoxVE : #Understanding #iSCSI and #SAN #Networks As the scale of a virtualization environment grows, data transfer speed and stability become key factors determining overall system performance While the NFS we covered in the last session involved file-level sharing, the #iSCSI (Internet Small Computer System Interface) we are learning today is an advanced technology that transfers data at the block level By utilizing #iSCSI , you can make an external storage device appear as if it were a local hard drive directly plugged into your server This forms the foundation of a #SAN (Storage Area Network) environment, often called the "flower of virtualization" In this #lecture , we will dig deep into the #method of connecting Proxmox nodes with external storage to build a high-performance #virtualization infrastructure, along with important precautions 1. Basic Concepts of #iSCSI and #SAN Environments To design an efficient syst...

  💾 #Heart of #ProxmoxVE #Data : #Mastering #Local #Storage #LVM and #ZFS When operating a #virtualization environment, the first physical limitation you often face is a shortage of storage space Beyond simply increasing capacity, how you store and manage data determines the overall #performance of the server and the safety of your data #ProxmoxVE natively supports #LVM (Logical Volume Manager), a traditional Linux-based storage management technology, and #ZFS , a next-generation file system Both technologies have distinct pros and cons, requiring appropriate selection and expansion based on your system's purpose In this #lecture , we will understand the structures of #LVM and #ZFS , the two pillars of local storage, and cover in-depth methods for adding disks to expand capacity and improve management efficiency 1. #LVM (Logical Volume Manager) Structure and Expansion Methods LVM is the most traditional and stable storage management method in Linux virtualization A. Co...

  📀 The Core of Virtualization Performance: Guide to #VirtualDisk Optimization In a #ProxmoxVE environment, when creating a Virtual Machine (VM), disk configuration is just as critical as hardware resource allocation. A virtual disk is not merely about choosing a capacity; the #CachingMode , which determines data read/write performance, and the type of disk controller significantly impact the overall responsiveness of the server. The settings for a database server, which requires high I/O performance, must be clearly distinguished from a standard web server where stability is the priority. In this course, we will deeply analyze the technical background of #DiskSize allocation and the different types of caching modes—the key to unlocking performance. 1. Virtual Disk Creation and Size Allocation Strategy The first gateway to determining the utility of a virtual machine is selecting the disk size and type. A. Considerations for Disk Size Allocation #ThinProvisioning : This is a me...
