# Gotgt 性能优化报告
|
||||
|
||||
## 优化概览
|
||||
|
||||
本次优化针对 iSCSI 目标协议栈的关键路径进行了性能提升，主要聚焦于减少内存分配和优化序列化操作。
|
||||
|
||||
## 性能提升对比
|
||||
|
||||
### iSCSI 协议层优化
|
||||
|
||||
| 函数 | 优化前 | 优化后 | 延迟降低 | 分配减少 |
|
||||
|------|--------|--------|----------|----------|
|
||||
| `DataInBytes` | 483.1 ns/op, 8 allocs | 411.7 ns/op, 1 alloc | **-15%** | **-87.5%** |
|
||||
| `DataInBytesSmall` | 192.0 ns/op, 8 allocs | 75.90 ns/op, 1 alloc | **-60%** | **-87.5%** |
|
||||
| `LoginRespBytes` | 55.80 ns/op, 1 alloc | 26.53 ns/op, 1 alloc | **-52%** | - |
|
||||
| `SCSIRespBytes` | 53.23 ns/op, 1 alloc | 21.89 ns/op, 1 alloc | **-59%** | - |
|
||||
| `R2TRespBytes` | 47.37 ns/op, 1 alloc | 18.52 ns/op, 1 alloc | **-61%** | - |
|
||||
| `MarshalUint32` | 15.03 ns/op, 1 alloc | 0.31 ns/op, 0 allocs | **-98%** | **-100%** |
|
||||
| `MarshalUint64` | 3.76 ns/op, 0 allocs | 0.31 ns/op, 0 allocs | **-92%** | - |
|
||||
|
||||
### SCSI 层性能
|
||||
|
||||
| 函数 | 性能指标 | 状态 |
|
||||
|------|----------|------|
|
||||
| `BuildSenseData` | 73.13 ns/op, 2 allocs | ✅ 良好 |
|
||||
| `GetSCSIReadWriteOffset` | 1.19 ns/op, 0 allocs | ✅ 优秀 |
|
||||
| `GetSCSIReadWriteCount` | 2.47 ns/op, 0 allocs | ✅ 优秀 |
|
||||
| `SCSIDeviceOperation` | 27.00 ns/op, 1 alloc | ✅ 良好 |
|
||||
| `SCSICommandTypeSwitch` | 2.05 ns/op, 0 allocs | ✅ 优秀 |
|
||||
|
||||
## 主要优化措施
|
||||
|
||||
### 1. 序列化函数优化
|
||||
|
||||
**文件**: `pkg/util/util.go`
|
||||
|
||||
- 使用 `binary.BigEndian.PutUint32/64` 替代循环位操作
|
||||
- 使用栈分配数组替代动态切片
|
||||
- 新增 `MarshalUint32To`/`MarshalUint64To` 零分配函数
|
||||
|
||||
```go
|
||||
// 优化前：动态分配切片
|
||||
func MarshalUint32(i uint32) []byte {
|
||||
var data []byte // 堆分配
|
||||
for j := 24; j >= 0; j -= 8 {
|
||||
b := byte(i >> uint32(j))
|
||||
data = append(data, b)
|
||||
}
|
||||
return data
|
||||
}
|
||||
|
||||
// 优化后：栈分配数组
|
||||
func MarshalUint32(i uint32) []byte {
|
||||
var data [4]byte // 栈分配
|
||||
binary.BigEndian.PutUint32(data[:], i)
|
||||
return data[:]
|
||||
}
|
||||
```
|
||||
|
||||
### 2. iSCSI 协议响应构建优化
|
||||
|
||||
**文件**: `pkg/port/iscsit/cmd.go`, `login.go`, `logout.go`
|
||||
|
||||
- 使用位运算替代循环计算填充：`dl := (m.DataLen + 3) &^ 3`
|
||||
- 直接使用数组索引赋值替代 `copy` + `MarshalUint64` 切片
|
||||
- 预分配精确大小的缓冲区，避免 `append` 导致的重新分配
|
||||
- 使用 `MarshalUint32To` 直接在缓冲区写入
|
||||
|
||||
```go
|
||||
// 优化前：多次分配和复制
|
||||
buf := make([]byte, 48, 48+rawDataLen+padding)
|
||||
copy(buf[16:], util.MarshalUint64(uint64(m.TaskTag))[4:])
|
||||
buf = append(buf, m.RawData...)
|
||||
|
||||
// 优化后：单次分配，直接写入
|
||||
buf := make([]byte, 48+rawDataLen+padding)
|
||||
util.MarshalUint32To(buf[16:], m.TaskTag)
|
||||
copy(buf[48:], m.RawData)
|
||||
```
|
||||
|
||||
### 3. TSIH 位图优化（已存在）
|
||||
|
||||
**文件**: `pkg/port/iscsit/iscsid.go`
|
||||
|
||||
- 使用位图实现 O(1) 复杂度的 TSIH 分配/释放
|
||||
- 并发安全，支持高并发连接
|
||||
|
||||
性能：
|
||||
- 并行分配：223.5 ns/op，0 分配
|
||||
- 顺序分配：27.42 ns/op，0 分配
|
||||
|
||||
### 4. 对象池优化（已存在）
|
||||
|
||||
**文件**: `pkg/port/iscsit/cmd.go`
|
||||

|
||||
ok github.com/gostor/gotgt/pkg/scsi 2.103s
|
||||

## 关键路径性能
|
||||
|
||||
### 典型 I/O 操作性能（估算）
|
||||
|
||||
基于基准测试结果，估算处理一个典型 4KB 读请求的性能：
|
||||
|
||||
| 操作 | 耗时 | 说明 |
|
||||
|------|------|------|
|
||||
| 解析请求头 | ~80 ns | parseHeader |
|
||||
| 构建 Data-In 响应 | ~412 ns | dataInBytes |
|
||||
| 命令处理开销 | ~27 ns | SCSIDeviceOperation |
|
||||
| **总协议开销** | **~520 ns** | 每命令 |
|
||||
|
||||
**理论最大 IOPS**（仅协议开销，不含磁盘 I/O）：
|
||||
- 单线程：~1.9M IOPS
|
||||
- 考虑实际磁盘 I/O (100μs)：~10K IOPS
|
||||
|
||||
## 生产环境建议
|
||||
|
||||
### 1. 内存池调优
|
||||
|
||||
根据实际工作负载调整 `sync.Pool` 的大小：
|
||||
|
||||
```go
|
||||
// 在 daemon 启动时预分配
|
||||
func init() {
|
||||
// 预分配 command pool
|
||||
for i := 0; i < 1000; i++ {
|
||||
cmd := &ISCSICommand{}
|
||||
commandPool.Put(cmd)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 批处理优化
|
||||
|
||||
对于大量小 I/O，考虑启用 iSCSI 多重命令和队列深度：
|
||||
|
||||
```json
|
||||
{
|
||||
"MaxQueueCommand": 64,
|
||||
"MaxOutstandingR2T": 4
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 日志级别
|
||||
|
||||
生产环境使用 `info` 或 `warn` 级别：
|
||||
|
||||
```bash
|
||||
./gotgt daemon --log warn
|
||||
```
|
||||
|
||||
## 后续优化方向
|
||||
|
||||
1. **零拷贝 I/O**: 使用 `splice` 或 `sendfile` 系统调用
|
||||
2. **批量提交**: SCSI 命令批量提交减少锁竞争
|
||||
3. **NUMA 感知**: 多 socket 系统上的内存分配优化
|
||||
4. **内核旁路**: 考虑 DPDK 或 io_uring 支持
|
||||
|
||||
## 结论
|
||||
|
||||
本次优化显著提升了 gotgt 的协议处理性能：
|
||||
|
||||
- ✅ **关键路径延迟降低 15-60%**
|
||||
- ✅ **内存分配减少 87.5%**（序列化操作）
|
||||
- ✅ **MarshalUint32/MarshalUint64 零分配**
|
||||
- ✅ **所有测试通过，race detector 无警告**
|
||||
- ✅ **go vet 无警告**
|
||||
|
||||
这些改进将直接转化为更高的 IOPS 和更低的延迟，特别是在高并发小 I/O 场景下。

Note that the examples directory is intended to show static configurations that serve as the backend storage. The simplest configuration has one LUN and one flat file behind the LUN in question. This json configuration file is read once at the beginning of the iSCSI target library instantiation.
|

|
||||
### Test
|
||||
## Performance Optimizations
|
||||
|
||||
gotgt includes several performance optimizations for high-throughput and low-latency storage workloads:
|
||||
|
||||
### 1. NUMA-Aware Memory Allocation
|
||||
|
||||
For multi-socket systems, gotgt can optimize memory allocation to use NUMA-local memory, reducing cross-socket memory access latency.
|
||||
|
||||
**Features:**
|
||||
- Automatic NUMA topology detection
|
||||
- NUMA-local buffer pools for I/O operations
|
||||
- Thread pinning to specific NUMA nodes
|
||||
- Configurable per-node buffer pool sizing
|
||||
|
||||
**Configuration:**
|
||||
```json
|
||||
{
|
||||
"performance": {
|
||||
"enableNUMA": true,
|
||||
"numaBufferPoolSize": 1024,
|
||||
"numaBufferSize": 262144
|
||||
},
|
||||
"storages": [
|
||||
{
|
||||
"deviceID": 1000,
|
||||
"path": "/var/tmp/disk.img",
|
||||
"online": true,
|
||||
"backendType": "file",
|
||||
"enableNUMA": true,
|
||||
"numaNode": 0
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 2. io_uring Backend Storage (Linux 5.1+)
|
||||
|
||||
On Linux systems with kernel 5.1 or later, gotgt can use io_uring for high-performance asynchronous I/O, bypassing the traditional Linux AIO interface.
|
||||
|
||||
**Features:**
|
||||
- Asynchronous I/O using io_uring
|
||||
- Reduced system call overhead
|
||||
- Better performance for high queue depth workloads
|
||||
- Automatic fallback to standard I/O on older kernels
|
||||
|
||||
**Requirements:**
|
||||
- Linux kernel 5.1 or later
|
||||
- x86_64, ARM64, or other supported architectures
|
||||
|
||||
**Configuration:**
|
||||
```json
|
||||
{
|
||||
"performance": {
|
||||
"enableIoUring": true,
|
||||
"ioUringQueueDepth": 4096
|
||||
},
|
||||
"storages": [
|
||||
{
|
||||
"deviceID": 1000,
|
||||
"path": "/var/tmp/disk.img",
|
||||
"online": true,
|
||||
"backendType": "iouring",
|
||||
"ioUringQueueDepth": 4096
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Backend Type Options:**
|
||||
- `file` - Standard file I/O (default)
|
||||
- `iouring` - io_uring-based I/O (Linux 5.1+)
|
||||
|
||||
### 3. Object Pooling
|
||||
|
||||
The iSCSI protocol layer uses sync.Pool for efficient object reuse:
|
||||
- ISCSICommand object pooling to reduce GC pressure
|
||||
- Buffer pooling for protocol header processing
|
||||
- NUMA-aware buffer allocation for data operations
|
||||
|
||||
### 4. Combined High-Performance Configuration Example
|
||||
|
||||
For maximum performance, combine both NUMA and io_uring:
|
||||
|
||||
```json
|
||||
{
|
||||
"storages": [
|
||||
{
|
||||
"deviceID": 1000,
|
||||
"path": "/var/tmp/disk.img",
|
||||
"online": true,
|
||||
"backendType": "iouring",
|
||||
"enableNUMA": true,
|
||||
"numaNode": 0,
|
||||
"ioUringQueueDepth": 4096
|
||||
}
|
||||
],
|
||||
"iscsiportals": [
|
||||
{
|
||||
"id": 0,
|
||||
"portal": "192.168.1.100:3260"
|
||||
}
|
||||
],
|
||||
"iscsitargets": {
|
||||
"iqn.2024-01.com.gotgt:fast-storage": {
|
||||
"tpgts": { "1": [0] },
|
||||
"luns": { "1": 1000 }
|
||||
}
|
||||
},
|
||||
"performance": {
|
||||
"enableNUMA": true,
|
||||
"enableIoUring": true,
|
||||
"ioUringQueueDepth": 4096,
|
||||
"numaBufferPoolSize": 1024,
|
||||
"numaBufferSize": 262144
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. Performance Tuning Tips
|
||||
|
||||
1. **NUMA Optimization**: On multi-socket systems, ensure the iSCSI target threads run on the same NUMA node as the storage devices
|
||||
2. **Queue Depth**: For NVMe or fast SSDs, increase `ioUringQueueDepth` to 4096 or higher
|
||||
3. **Buffer Sizes**: Match `numaBufferSize` to your typical I/O size (e.g., 64KB, 128KB, 256KB)
|
||||
4. **CPU Pinning**: Use `numaNode` to pin storage backends to specific NUMA nodes
|
||||
|
||||
### 6. Benchmarking
|
||||
|
||||
Use fio to benchmark performance:
|
||||
```bash
|
||||
fio --name=iscsi-test --ioengine=libaio --iodepth=32 \
|
||||
--rw=randread --bs=4k --direct=1 --size=1G \
|
||||
--filename=/dev/sdX
|
||||
```
|
||||
|
||||

# Performance Optimizations for gotgt
|
||||
|
||||
This document describes the performance optimizations implemented for gotgt, focusing on NUMA-aware memory allocation and io_uring backend storage support.
|
||||
|
||||
## Overview
|
||||
|
||||
Two major performance optimizations have been implemented:
|
||||
|
||||
1. **NUMA-Aware Memory Allocation** - Optimizes memory access patterns on multi-socket systems
|
||||
2. **io_uring Backend Storage** - Provides high-performance asynchronous I/O on Linux 5.1+
|
||||
|
||||
## 1. NUMA-Aware Memory Allocation
|
||||
|
||||
### What is NUMA?
|
||||
|
||||
Non-Uniform Memory Access (NUMA) is a memory design used in multi-processor systems where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors).
|
||||
|
||||
### Implementation
|
||||
|
||||
The NUMA support is implemented in `pkg/util/numa/`:
|
||||
|
||||
- **Topology Detection** (`numa.go`, `numa_linux.go`): Automatically detects NUMA topology using `/sys/devices/system/node/` filesystem
|
||||
- **NUMA-Local Buffer Pool** (`pool.go`): Provides buffer pools that allocate memory from local NUMA nodes
|
||||
- **Thread Pinning** (`numa_linux.go`): Allows threads to be pinned to specific NUMA nodes
|
||||
|
||||
### Key Components
|
||||
|
||||
#### NUMABufferPool
|
||||
|
||||
```go
|
||||
pool := numa.NewNUMABufferPool(&numa.BufferPoolConfig{
|
||||
BufferSize: 256 * 1024, // 256KB buffers
|
||||
PerNodePoolSize: 1024, // 1024 buffers per node
|
||||
EnableNUMA: true,
|
||||
})
|
||||
|
||||
buf := pool.Get() // Get buffer from local NUMA node
|
||||
// use buffer...
|
||||
pool.Put(buf) // Return buffer to pool
|
||||
```
|
||||
|
||||
#### Thread Pinning
|
||||
|
||||
```go
|
||||
// Pin current goroutine to NUMA node 0
|
||||
numa.PinThreadToNode(0)
|
||||
defer numa.UnpinThread()
|
||||
|
||||
// Or use RunOnNode for a function
|
||||
numa.RunOnNode(0, func() {
|
||||
// This function runs on NUMA node 0
|
||||
})
|
||||
```
|
||||
|
||||
### Performance Benefits
|
||||
|
||||
- Reduced memory latency by accessing local NUMA nodes
|
||||
- Better cache utilization
|
||||
- Reduced cross-socket traffic
|
||||
- Predictable performance on multi-socket systems
|
||||
|
||||
### Configuration
|
||||
|
||||
Enable NUMA support in the configuration file:
|
||||
|
||||
```json
|
||||
{
|
||||
"performance": {
|
||||
"enableNUMA": true,
|
||||
"numaBufferPoolSize": 1024,
|
||||
"numaBufferSize": 262144
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 2. io_uring Backend Storage
|
||||
|
||||
### What is io_uring?
|
||||
|
||||
io_uring is a Linux kernel interface for asynchronous I/O that was introduced in Linux 5.1. It provides a highly efficient interface for submitting and completing I/O operations with minimal system call overhead.
|
||||
|
||||
### Benefits of io_uring
|
||||
|
||||
- Reduced system call overhead (batching of operations)
|
||||
- Lower latency for I/O operations
|
||||
- Higher throughput especially for high queue depth workloads
|
||||
- Better CPU efficiency
|
||||
|
||||
### Implementation
|
||||
|
||||
The io_uring backend is implemented in `pkg/scsi/backingstore/iouring/`:
|
||||
|
||||
- **Async I/O Operations**: Read, Write, and Fsync using io_uring
|
||||
- **Queue Management**: Configurable queue depth
|
||||
- **Fallback Support**: Automatically falls back to regular I/O on older kernels
|
||||
|
||||
### Usage
|
||||
|
||||
Enable io_uring in the storage configuration:
|
||||
|
||||
```json
|
||||
{
|
||||
"storages": [
|
||||
{
|
||||
"deviceID": 1000,
|
||||
"path": "/var/tmp/disk.img",
|
||||
"online": true,
|
||||
"backendType": "iouring",
|
||||
"ioUringQueueDepth": 4096
|
||||
}
|
||||
],
|
||||
"performance": {
|
||||
"enableIoUring": true,
|
||||
"ioUringQueueDepth": 4096
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Backend Type Options
|
||||
|
||||
- `file` - Standard synchronous file I/O (default)
|
||||
- `iouring` - io_uring-based asynchronous I/O (Linux 5.1+)
|
||||
|
||||
### Requirements
|
||||
|
||||
- Linux kernel 5.1 or later
|
||||
- x86_64, ARM64, or other supported architectures
|
||||
- O_DIRECT support recommended for best performance
|
||||
|
||||
## 3. Combined Configuration Example
|
||||
|
||||
For maximum performance, combine both NUMA and io_uring:
|
||||
|
||||
```json
|
||||
{
|
||||
"storages": [
|
||||
{
|
||||
"deviceID": 1000,
|
||||
"path": "/var/tmp/disk.img",
|
||||
"online": true,
|
||||
"backendType": "iouring",
|
||||
"enableNUMA": true,
|
||||
"numaNode": 0,
|
||||
"ioUringQueueDepth": 4096
|
||||
}
|
||||
],
|
||||
"iscsiportals": [
|
||||
{
|
||||
"id": 0,
|
||||
"portal": "192.168.1.100:3260"
|
||||
}
|
||||
],
|
||||
"iscsitargets": {
|
||||
"iqn.2024-01.com.gotgt:fast-storage": {
|
||||
"tpgts": { "1": [0] },
|
||||
"luns": { "1": 1000 }
|
||||
}
|
||||
},
|
||||
"performance": {
|
||||
"enableNUMA": true,
|
||||
"enableIoUring": true,
|
||||
"ioUringQueueDepth": 4096,
|
||||
"numaBufferPoolSize": 1024,
|
||||
"numaBufferSize": 262144
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 4. Performance Tuning Guide
|
||||
|
||||
### NUMA Tuning
|
||||
|
||||
1. **Determine NUMA Topology**:
|
||||
```bash
|
||||
numactl --hardware
|
||||
lscpu | grep NUMA
|
||||
```
|
||||
|
||||
2. **Align Network and Storage**:
|
||||
- Ensure network interfaces are on the same NUMA node as the iSCSI process
|
||||
- Place storage devices on the same NUMA node if possible
|
||||
|
||||
3. **Buffer Pool Sizing**:
|
||||
- `numaBufferPoolSize`: Number of buffers per node (default: 1024)
|
||||
- `numaBufferSize`: Size of each buffer (default: 256KB)
|
||||
- Size based on expected concurrent I/O and I/O size
|
||||
|
||||
### io_uring Tuning
|
||||
|
||||
1. **Queue Depth**:
|
||||
- Higher queue depth = better throughput, higher latency
|
||||
- Lower queue depth = lower latency, lower throughput
|
||||
- Typical values: 128-4096 depending on workload
|
||||
|
||||
2. **I/O Size**:
|
||||
- Match application I/O size for best efficiency
|
||||
- Use direct I/O (O_DIRECT) to bypass page cache if appropriate
|
||||
|
||||
3. **System Limits**:
|
||||
```bash
|
||||
# Check current limits
|
||||
ulimit -a
|
||||
|
||||
# Increase if needed (in /etc/security/limits.conf)
|
||||
* soft nofile 1048576
|
||||
* hard nofile 1048576
|
||||
```
|
||||
|
||||
## 5. Benchmarking
|
||||
|
||||
Use the following tools to benchmark performance:
|
||||
|
||||
1. **fio** (Flexible I/O Tester):
|
||||
```bash
|
||||
fio --name=iscsi-test --ioengine=libaio --iodepth=32 \
|
||||
--rw=randread --bs=4k --direct=1 --size=1G \
|
||||
--filename=/dev/sdX
|
||||
```
|
||||
|
||||
2. **iperf3** (for network bandwidth):
|
||||
```bash
|
||||
iperf3 -c <target-ip> -p 3260
|
||||
```
|
||||
|
||||
3. **iscsi-perf** (if available from libiscsi)
|
||||
|
||||
## 6. Troubleshooting
|
||||
|
||||
### NUMA Issues
|
||||
|
||||
- Check if NUMA is available: `numa.Available()`
|
||||
- Verify topology detection: Check logs for NUMA node count
|
||||
- Thread pinning failures: Ensure sufficient privileges (CAP_SYS_NICE)
|
||||
|
||||
### io_uring Issues
|
||||
|
||||
- Kernel version check: `uname -r` (must be 5.1+)
|
||||
- io_uring availability: Check if `/proc/sys/kernel/io_uring_disabled` exists
|
||||
- Permission issues: Ensure user has appropriate file permissions
|
||||
|
||||
## 7. Future Enhancements
|
||||
|
||||
Potential future optimizations:
|
||||
|
||||
1. **DPDK Support** - Kernel-bypass networking for iSCSI
|
||||
2. **SPDK Integration** - User-space NVMe driver support
|
||||
3. **CPU Affinity Configuration** - Fine-grained CPU pinning
|
||||
4. **Memory Interleaving** - Automatic memory interleaving policies
|
||||
5. **Adaptive Buffer Sizing** - Dynamic buffer pool sizing based on workload

|
||||
|
||||
### Recent Fixes
|
||||
|
||||
#### Bug Fix: SCSICDBBufXLength Function (2025-03-10)
|
||||
|
||||
Fixed incorrect Allocation Length calculation for 6-byte CDB commands:
|
||||
|
||||
1. **INQUIRY (0x12) and REQUEST_SENSE (0x03)**: Use bytes 3-4 for Allocation Length
|
||||
2. **Other Group 0 commands (READ_6, WRITE_6, etc.)**: Return `ok=false` since these commands don't have Allocation Length field in their CDB. This prevents incorrect truncation of sense data buffer.
|
||||
|
||||
#### Bug Fix: CDB Group ID Comparison (2025-03-10)
|
||||
|
||||
Fixed incorrect comparison between CDB length constants and group IDs:
|
||||
- Original: Used CDB length constants (6, 10, 12, 16) which were incorrect
|
||||
- Fixed: Use actual group IDs (0-7) for switch statement
|
||||
|
||||
#### Bug Fix: PERSISTENT_RESERVE_IN/OUT (0x5E/0x5F) (2025-03-10)
|
||||
|
||||
Fixed Allocation Length position for these commands:
|
||||
- Use bytes 6-7 instead of bytes 7-8
|
||||
- Added manual BigEndian conversion for correct byte order
|
||||
|
||||
## Notes
|
||||
|
||||
### Block Device Characteristics VPD Page (0xB1)
|
||||
|
||||
This VPD page is currently not supported. The INQUIRY command will return a CHECK CONDITION status with ILLEGAL_REQUEST sense key when this page is requested. This is expected behavior and does not affect normal operations.
|
||||
|
||||
### Persistent Reservations
|
||||
|
||||
- All standard reservation types are supported: Write Exclusive, Exclusive Access, and their variants with registrants only.
|
||||
- Reservation scopes: LU (Logical Unit) scope is supported.
|
||||
- Persistent reservation operations require proper key registration before use.
|
||||
|
||||
### Thin Provisioning
|
||||
|
||||
- UNMAP command is fully supported for thin-provisioned LUNs.
|
||||
- Logical Block Provisioning VPD page (0xB2) reports thin provisioning capabilities.
|
||||
|
||||
## Version Information
|
||||
|
||||
- SPC Version: SPC-3 (with some SPC-4 features)
|
||||
- SBC Version: SBC-2 (with some SBC-3 features)
|
||||
- iSCSI Protocol: RFC 3720 compliant
